“[Abraham] then brought some curds and milk and the calf that had been prepared, and set these before them. While they ate, he stood near them under a tree.”
– Genesis 18:8
Consider the miracle and mystery of cheese. You take milk. You combine it with the sloughed-off lining of the stomach of a calf called rennet. Store it away and in a few days or weeks and voila! We got cheese!
Neolithic tribes worshiped cheese. Since then, cheese has been intimately entwined with civilization. But for Jews, cheese poses a special problem. The Torah forbids Jews to cook the meat of the kid with the milk of the mother, possibly because of its intrinsic cruelty. In the mystical tradition, milk represents mother’s nurturing and it comes from sheep and cows and goats, animals we domesticate and nurture. Meat requires spilling blood. It is predatory and reminds us of our bestial natures. Milk, then, needs to be protected from meat. They should never touch, and when they have to interact, Jews erect barriers in time and space to separate them. Over the centuries, this has evolved into an elaborate system of kosher rules separating all meat foods from anything that has touched milk. So while serving our body’s need for sustenance by eating milk and meat, kosher laws remind us of the sources of our food. We discipline our cognizance and actions in eating them at separate times off of separate dishes and cooking them in separate pots. Kosher eating is mindful eating.
With all this invested in the barrier between the two realms, then how is it possible that cheese, made with lining from a cow’s stomach, somehow gets an exemption? The sages of the Talmud give us what seems like a technical reason, but as Aeschylus said, “Wrong should not get by on a technicality.” If we look closely though, we’ll see that the technicality anticipates discoveries only recently made by science. The details of their apparent foreknowledge suggests that the Torah is a channel for knowing things that are only slowly revealed over the millenia by science. To put it more simply, though as a rational modern I resist this conclusion, it seems science is catching up to wisdom revealed thousands of years ago to the Jews. To see that this is more than just a coincidence and the Talmud’s technicalities reveal a true understanding of the science of cheese, we’ll have to dip into we’ve learned more recently about the science behind the magic of cheese.

’כהיומ הזה’ – “…even like today” – Chanukah prayer
This is dedicated to my son, Avraham Benyamin (Ben) Porush, whose birthday is the first day of Chanukah and bris the last.
Why does the Talmud warn against teaching Greek to Jewish children?
The last pages of the Talmud volume Sotah portrays the decline of Jewish spirit after the destruction of the Temple. It marches through a long, dispiriting list of the horrible things that happen as Jews have to abandon customs that could only be kept alive when there was a spiritual center in Jerusalem and they lived as a nation inside their own borders.
In the middle of this lamentation (called Yeridas HaDoros – “decline of the generations”), the Talmud warns somewhat mysteriously that fathers shouldn’t teach Greek to their sons.What did the Sages have in mind? They can’t have meant Greek language, because the Rabbis were conversant with Greek and spoke it in the streets of Jerusalem. By the first century CE, and almost certainly earlier, it had displaced Hebrew as the lingua franca. And in various places in the Talmud, Greek is praised as the only language into which the Torah can be elegantly translated. Indeed, Sotah itself recounts a lament of Shimon ben Gamliel, the great Sage (50 CE) that shows how much the rabbis thought of Greek:
Why does the Talmud warn us against teaching our children Greek?
Chanukah is sometimes thought of as a more minor holiday in the traditional Jewish calendar. Yet it gives us a way to understand a challenge Jews continue to face as they to try to thrive in the modern world: the seductions of “Greek” philosophy.

Why does the Talmud forbid teaching Greek?
The last page of the Talmud tractate Sotah brings to a climax the apocalyptic portrait of the decline of Jewish generations, spirit, learning and virtue after the destruction of the Temple. It marches through a long, dispiriting list of the horrible things that happen as the generations decline and have to abandon customs that could only be kept alive when there was a spiritual center in Jerusalem. In the middle of this lamentation (called the Yeridas HaDoros – “descent of the generations”), the Talmud warns somewhat mysteriously that fathers shouldn’t teach Greek to their sons.
DURING THE WAR OF TITUS [Chorban 67-70 CE] THEY [the Sages] DECREED AGAINST THE USE OF CROWNS WORN BY BRIDES AND THAT NOBODY SHOULD TEACH HIS SON GREEK. …….
What did the Sages have in mind? They can’t have meant Greek language, because the Rabbis were conversant with Greek, spoke it in the streets of Jerusalem, and it had displaced Hebrew as the lingua franca among the educated classes. In various places in the Talmud, Greek is praised as the only language into which the Torah can be elegantly translated, as Akiva asked Onkelos to do (the Targum). In the commentary, we read the lament of Shimon ben Gamliel, the great Sage (50 CE), who boasts of the Greek wisdom in his father’s yeshiva:
There were a thousand pupils in my father’s house; five hundred studied Torah and five hundred studied Greek wisdom.
Chanukah: Greek vs. Hebrew Part I
The events we celebrate on Chanukah happened following Jerusalem’s conquest by the Greeks in 332 BCE. Around 167-165 BCE, the Greek king Antiochus II, as part of his general purging of the Greek empire of foreign influence, outlaws Judaism and defiles the Temple. Matisyahu, Judah the Maccabee, recaptures and purifies it. He lights the lamp of the Temple, and miraculously one night’s worth of oil stays lit for eight nights. Chanukah miracle of lights because it is an eternal reminder of the re-assertion of Jewish holiness over Greek idolatry and materialism.
In 76-67 BCE – Hyrcanus and Aristobulus great-grandnephews of Judah HaMaccabee, split the kingdom between the Seleucid [Greek] faction, seeking to accommodate Hellenism, and the Pharisees, separatists who wanted to protect the purity of Jewish ritual and the Temple from these modern influences. Aristobulus seizes Jerusalem and the Temple. Hyrcanus besieges him. The Talmud tells the aggadah (story) of an old man inside the walls of Jerusalem who communicated via secret code, Greek, who betrayed the defenders of Jerusalem to their Greek besiegers:
AND THAT NOBODY SHOULD TEACH HIS SON GREEK. Our Rabbis taught: When the kings of the Hasmonean house fought one another, Hyrcanus (Seleucid) was outside of Jerusalem and Aristobulus (Pharisees) was on the inside. Each day those within the city would let down dinarim [coins] in a pouch over the city wall and Jews of the Hyrkanos faction would in return send up for them lambs for the daily communal sacrifice. There was within Jerusalem a certain old man who was familiar with Greek wisdom, and he communicated surreptitiously with the besiegers in the language of Greek wisdom saying to them, “As long as those within the Jerusalem walls engage in the sacrificial service, they will not be delivered into your hands.” On the morrow, they lowered the dinarim in a pouch, but the besiegers following the advice of the old man and, seeking to prevent the service, sent them up a swine. When the swine reached midway along the wall and stuck out its hooves into the wall, Israel quaked over an area of four hundred parsahs [1600 square miles]. At that time, they declared, “Cursed be the man who shall raise pigs and cursed be the man who shall teach his sons Greek wisdom.”
Sotah 49b [This aggadah [story] is repeated in Bava Kamma 82B and Menachot 64b]
What is the deeper meaning of this story? The placement of this prohibition against Greek wisdom in the dramatic end of Sotah, the selection of this story of the traitor who betray Judaism from within Jerusalem by means of secret Greek wisdom, the quaking of all of Eretz Yisroel, draw our attention to deeper currents. What are the Rabbis warning us against? What is the historical context? What do they mean by “Greek wisdom”?
Rashi [1040-1105 CE] explains that “Greek wisdom” refers to a set of cryptic expressions of gestures understood only by the paladin (palace dwellers), not by common people. But what was this secret code? The answer lies in the parallel track of philosophy preserved by Christianity that they inherited from the Greeks: Pythagoreanism.
Pythagoras and the Neo-Pythagorean revival in the Talmudic Era
Pythagoras is the father of Greek philosophy. His influence over all of Western thought, even into our twenty-first century, has remained strong in a way I will explain in a moment. But first, who was Pythagoras beyond the inventor of the Pythagorean Theorem we learned in middle school?
Pythagoras (570-490 BCE) was the son of Greek nobility. Around 550 he travels around the Middle East and Mediterranean for twelve years. He travels to Egypt. On his way back, he stops at Mt. Carmel to visit Elijah’s cave for several weeks. He then journeys to Babylon at a time that would have coincided with the Jewish exile. Inspired the wisdom and mysticism of these other cultures, he returns to Greece and founds a mystic-scientific-communal brotherhood preaching asceticism, mystical number theory, the “divine” tetractys, and the transmigration of souls.
Reality is ONLY that which can be measured and understood, delved by rational numbers. Our mastery of their secrets enable humans to become “gods.”
He invents word “philosophy” – that is, lover of knowledge.
He inspires Plato’s distinction between being and becoming: the notion that the universe is fixed and constant beneath its constant state of flux.
In turn, he inspires Aristotle’s rational, orderly vision of cosmology: the universe can be arranged and ordered into a complete, coherent, unified system. It is governed by logic. Reason is the highest attribute of human nature. To be rational is also to be ethical and therefore, divine.
Cosmology: The universe is ruled by rational numbers and their manipulation (mathematics).
The sign of the cult is the mystical Tetractys…
…seems to be an idea of numbers Pythagoras melds with the Jewish Tetragrammaton, the Four Divine Letters of God’s Name, that he might have picked up on his journey through ancient Israel.
Pythagoras instituted a dominant theory or discipline of Arithmetika theologomena, virtually equivalent to the Jewish gematria, the system of calculating Hebrew letters as numbers to discover further meaning, God’s intention, in the Torah. The entwinement of the two concepts is intimate; maybe Pythagoras imported it from his contact with Judaic mysteries in Israel and Babylon. It should also be noted, though, that the word gematria has a Greek origin: it is a cognate of ‘gamma + tria’ and bears etymological relationship to geometry and grammar
He believed in the Transmigration of souls – a Jewish concept of gilgulim. The soul is to be freed from the “muddy vesture of decay” of the body by ascetic practices and secret wisdom. Matter is evil.
Contemplation of the universe from reason – rational thought – is the highest human activity.
Pythagoreans also communicated via a system of secret signs, numerical codes, and hand gestures which they used while enforcing their famous discipline of ascetic silence. One of these signs, in fact the only one we know of for sure that survives to today, is the same as the split-fingered gesture of the Kohanim which Pythagoreans used for “salut,” a deep concept for them signifying cleanliness, purity, ethical truth, and blessing or greeting. Maybe this is precisely the secret code the traitorous old man used to betray Jerusalem to the Greek sympathizers.
So we can see what the Talmud is concerned about. Pythagoreanism was a seductive and powerful philosophy, a form of secular/pagan theology that would have been, and was, attractive to Jews, with their love of learning and wisdom and esoteric knowledge. Indeed, between the second century BCE and second century CE, as the Talmud begins, Pythagoreanism enjoys a huge revival in Roman culture, what we now call neo-Pythagoreanism. Cicero, the famous Roman senator, and his good friend in the Senate, Nigidius Figulus, lead the revival around 50 BCE. Nigidius writes a 27-volume treatise of mathematics, grammar, astronomy and magic that becomes a classic, along with Cicero’s work, for centuries.
In the first century CE, the sect of neo-Pythagoreans construct a Pythagorean Temple underground, at Porto Maggiore in Rome. It combines elements of paganism and Christianity. It is the site of secret sacrificial rites, necromancy, and is filled with images of the Greek gods. At the same time, it has an apse and nave, a new architectural form built with the Pythagorean ‘golden mean’ but is meant to represent the cross, the same architecture we see in the great cathedrals of the Christian Europe and even in the humblest wooden Baptist churches today.
But the connection is more than architectural. With its notion of the perfectability of man, the notion that matter is evil and corrupt from which reason needs to be freed, you can see that this Pythagorean Greek wisdom lays the groundwork for the flowering of Christian theology soon thereafter.
At the same time, the allure for Jews must have been great. Here for instance, is a vow pledged by the Roman Neo-Pythagoreans which echoes the Tetragrammaton (the four Hebrew letters of God’s Name):
A Neo-Pythagorean Oath from the 1st c CE: “By that pure, holy, four lettered name on high/nature’s eternal fountain and supply/the parent of all souls that living be/by him, with faith find oath, I swear to thee.”
The essence of neo-Pythagoreanism is a way of thinking that we would find very comfortable as 21st century moderns:
The universe is ruled by rational numbers and logic.
All that is known is only that which can be touched and measured and calculated and observed.
Humans can become divine by application of reason.
Because there are so many similarities to Jewish concepts, one could see how the Seleucid Jews would find assimilation so attractive, and why Jewish thinkers and students could be seduced, even from within the walls of Jerusalem itself. Indeed, the Rambam, in Guide for the Perplexed, calls Aristotle “half a prophet.” But which half? Why half? Rambam says Aristotle fell short because he equated human nature with rationality alone. Aristotle’s ‘thinking being’ strives to rule the world through subjugation and calculation; Maimonides “praying being” can be king of the world by elevating it. “When there’s nothing higher than intellect, intellect has no guiding light.”
Greek wisdom, the secret Pythagorean code, represented the hoof of the swine touching Jerusalem’s walls in the fight between traditionalists and Greek modernists, and the betrayal and defeat by the latter of the former, the Pharisee’s tradition that would later become rabbinic (Talmudic) Judaism. The smallest contamination shakes the entire foundation of Israel itself.
Perpetual Chanukah in the West: From Pythagoras to the Holocaust
All this would be just an interesting historical exercise showing the historical entwinement between Greek and Talmudic thought if it weren’t for the fact that, in clear purity of form, Pythagoreanism still holds sway today.
Pythagoreanism is the fundamental constant across the history of Western culture. It connects the Hellenic culture of 5th c BCE of Plato, Socrates and Aristotle with Roman culture. It connects Roman philosophy that dominated in the time of the destruction of the Second Temple with Christianity in the centuries soon to follow. Pythagoreanism represents a continuous tradition of the perfectability of humans and the basis of the universe and everything in it as reducible to rational, deterministic, unified laws.
Greek philosophy institutes a vision of the deities who created a clockwork universe of perfection, instituting immutable, static laws of physics and nature. The gods set it motion and let it run. This is a scientific cosmology that still holds sway today in the common mind. It keeps us from awakening from the great cybernetic delusion of our last century, that we can create an artificial intelligence, mind, or neshama through the application of computer codes and algorithms. It still governs most of what we’re taught in school and our still Newtonian-Pythagorean concept of the universe. But this conception has nuanced, though absolutely critical, differences from Jewish metaphysics.
Contrast Greek philosophy to our Jewish cosmology of an unfolding universe. God, whose Face is always receding and hidden, creates the cosmos. In the Christian concept, the Word – Logos – becomes flesh and utterly knowable and personal, an idea developed by the neo-Pythagoreans in the first century. The Divine Attention of HaKodesh Borechu continuously sustains an unfolding universe. Even the method of Jewish hermeneutics – how we argue and discourse to arrive at the truth – contrasts sharply with the Greek. You need only compare a page of any conventional Western book with any page of the Talmud to get the idea. One signifies a simple, clear stream of letters marching in lines across the page as the story proceeds in orderly fashion from beginning to middle to end. Open the Talmud, however, and you are plunged into a hypertextual jumble: a noisy symposium capturing voices and commentaries and commentaries on commentaries separated by centuries and hundreds of miles and cultures. The choppy sea of Talmud exemplifies what Plato scorned as chaotic, subjective “aesthetika” and “rhetorika” as opposed to his orderly “logos.”
If we trace the history of this contrast between Greek and Hebrew, between Seleucids and Pharisees, between Pythagoreanism and the Talmud even until today, we see there is ongoing violence in the hyphen that the sages of the Talmud anticipated. Indeed, this story of the betrayal of Jerusalem by Greek wisdom and the prohibition against teaching it is prophetic. The story of the Temple sacrifice befouled by a swine, the story of the shaking of the walls of Jerusalem, are warnings that reach back to original Chanukah – already a couple of centuries old when the Talmud story is told – and forward to all of Western philosophy, including postmodernism today. The subtle but fundamental incompatibility between these two philosophies leads to what I call “philosophical violence in the Judaeo-Christian hyphen.” With the burning of the Talmud throughout Europe and the many trials Jews have suffered under the rule of Christianity, including the Holocaust, this violence is not just philosophical.
The twentieth century begins with work by Alfred North Whitehead and Bertrand Russell, Principia Mathematica, “showing” that all thought can be reduced to mathematically rigorous logic. Russell later wrote that “the European tradition … consists of a series of footnotes to Plato.” [Process and Reality: An Essay in Cosmology (1929)]. Even later, in his History of Western Philosophy (1945), Russell declares Pythagoras the greatest of all philosophers. Interestingly, Russell’s last act, literally, in his life, is meant to shake the whole land of Israel. Though a pre-State supporter of Zion, his final political statement, read the day after his death in 1970 in Cairo, condemns Israel’s aggression against Egypt in 1967 and demands retreat to pre-1967 borders.
In the 1920s, Martin Heidegger reinserts Pythagoreanism, an updating of the Greco-Christian Being vs. Becoming duality, into the heart of philosophy. Without going into his extraordinary influence over the twentieth century, including the postmodernism and deconstruction, suffice it to say that virtually every thinker and theorist since has to grapple with Heidegger and has been influenced by him.
However, two recent works of scholarship suggest the prescience of the Talmud’s warning in Sotah. Victor Farias, in Heidegger and Nazism (1987) and Emanuel Faye in Heidegger: The Introduction of Nazism into Philosophy (2005) show how Heidegger, who was an unapologetic and avowed Nazi, introduced Nazi violence into the scene of contemporary Western philosophy. In the 1980s, his chief heir and leader of the Yale school of deconstruction, Paul DeMan, was exposed as having been a Nazi collaborator and writer during WWII. The monumental French thinker Jacques Derrida, himself an Algerian Jew, rose to DeMan’s defense in a shameful chapter in the history of postmodern thought.
Reconciliation through “Jewish Physics”: Quantum Cosmology
But let me end on a note of reconciliation. Realizing there is violence in the hyphen paves the road to recognizing the inert nature of Pythagorean philosophy. The recent works by Farias and Faye expose the link between Nazism and empty philosophies of materialism, constructivism, deconstruction and moral relativism that have lain at the core of Western thinking itself, philosophies that lead to mechanization and disregard for the sanctity of all human existence. It is the same Greek chochma [wisdom] that lay in the heart of the traitor of Jerusalem and is that tempts ongoing Jewish assimilation to Western culture.
In our newfound skepticism about the darkness at the heart of postmodernism, there is hope for a new deepening. This is especially true because the philosophical turn has been accompanied by a revolution in our scientific concept of how the universe works. Together, the two revolutions hold promise for how Jewish thinking may influence the future of Western civilization.
For a century, our scientific understanding of the fundamental principle of the universe has been grappling with what we can call “Jewish Physics.” In calling it this, I am echoing the notorious propaganda of Nazis in the 1930s, who called it “Jew Physics.” (See Klaus Hentschel and Ann Hentschel, Physics and National Socialism. Springer, 2011). This revolution has been led by Jews, starting with Einstein at the Institute for Advanced Studies at Princeton in the 1920s, and includes Niels Bohr, Eugene Wigner, James Franck, Otto Stern, I.I. Rabi, Wolfgang Pauli, Robert Hofstadter, Richard Feynmann, Murray Gell-Mann, Sheldon Glashow, Steven Weisenberg, Jerome Friedman, Martin Lewis Perl, Frederick Reines, David Gross, Adam Riess, Saul Perlmutter, Serge Haroche, and Francois Englert. These are just half of the Jewish winners of the Nobel Prize for Physics in the last century, and a mere fraction of the Jews who are busy in the field of quantum mechanics and theoretical physics. Many of them fled Nazism to seek refuge – and freedom of inquiry – in America
Quantum mechanics has introduced a cosmological question that shakes our understanding of the universe itself as merely deterministic and rational. Put simply, it brings us to a crossroads of our understanding. Either the universe splits into an infinite chaos of uncertain and inaccessible universes every time there is a quantum event, and all sub-atomic events are connected by unproven superstrings of 11 or some other number of dimensions;
There is a Universal Intelligence that turns His face to every event in the cosmos and by His Attention, creates the reality we inhabit. This subject is obviously too broad and deep and abstruse to do justice to here today, but let me gesture at just one small tear in the veil between Western science and Jewish religion: the confirmation of the existence of the Higgs Boson – the so-called “God Particle” – and its measurement at the Large Hadron Collider at CERN (France). Suffice it to say for now, science is confronted with the introduction of metaphysics back into physics, this time ushering in an era of what I hope and pray will be the reassertion of Jewish metaphysics into Western cosmology.

1987, 2005 – Victor Farias, Heidegger and Nazism and Emanuel Faye, Heidegger: The Introduction of Nazism into Philosophy
In recent years, matzah seems tastier to me. I don’t know whether it’s because I’ve got so many good associations with the other tastes of the holiday, including brisket, matzah brie, gefilte fish, and macaroons. Or maybe the shmurah (super-orthodox watched-while-it’s-baked) matzah we now get is better than Manischevitz of yore. But I’m probably fooling myself. Matzah really is the bread of affliction. It’s dusty, dry, brittle, tasteless, mean fare. Every year, I ask the ancient theological questions plaguing the Jews, “Does matzah ever go stale? Would anyone know? Why would such a dispiriting food be so central to the most delightful, and perhaps the most important, Jewish holiday? Why is matzah so important that even the Torah calls Passover The Holiday of Matzahs?“
Matzah is itself and an invitation to interpretation
Like many things in Jewish ritual, matzah is both itself and symbolic of many other things all at once. When we eat matzah, we collapse the 3330 years between us and our slave ancestors by reliving the sensation of the Children of Israel, who ate matzah on the night before the Exodus. They then ate it a second time when they didn’t have time to let the bread rise before we exited Egypt. We can taste what it’s like to be slaves who cannot choose the bread they eat. Matzah means itself.
For something so flat, matzah also has so many layers of meaning that it seems to be a paradox about layering. It is flat but infinitely deep. During the seder, we focus on the difference between bread and matzah and bring out the symbolism that makes it the centerpiece of Passover. This is one of the beauties of the seder: along with teaching children the central story of our people, it also teaches them a way of thinking. The matzah and the other objects on the seder plate multiply meanings, which we somehow hold in parallel in our minds like a symphonic theme weaving in and out of different instruments and keys through the course of a performance. Somehow, the meanings don’t clash. They magically harmonize and make each other grander. Even more amazingly, after all the sermons, the things in front of us, the egg, greens, bitter herbs, matzah, charoset and wine remain fully themselves. In the end, though, we still get to eat them, to ingest the sermon.
Even at my grandfather’s home, where he blazed through the seder in Hebrew (he was born in Jerusalem in 1899), Passover seemed like deliverance from the slavery of school. Compared to the arguments of the seder, school was all rote learning and dull algebra, a race to get the one right answer. In school, the signifier meant one thing only, a simple tune played on a three-penny pipe. The seder was a tutorial about the promised land of full-throated, orchestral argument, where even children are urged to join in. The other grand traditions of our seder – the red-faced shouting about politics and the cutthroat 25 cent pinochle game at the end – all seemed to flow from the sages in Bnei Brak who tried to one-up each other over the number of plagues. Such disagreements, as Rav Kook said, are a noisy route to universal peace.
That’s why this year I was so childishly excited to discover a new sermon in matzah that harmonized with all the others. By looking at the most literal physics of its nature, this is what I saw:
Matzah is a sermon on God’s absence. By noting matzah is not bread, we open a door, inviting Him to enter the home during the seder. It is the secret twin of Elijah’s Cup, asking the same question left by the untouched wine in Elijah’s cup: Where is He?
The Matzah Sermons
The Matzah Sermon has many versions.
We forego bread because the difference between bread and matzah is inflation, the chewy fullness that grants satisfaction. We should beware our own puffed-up egos and liberate ourselves from enslavement to the things that make us too swollen with pride and arrogance.
The difference between bread and matzah is our taste for sensuality, so beware enslavement to material things that give us sensuous pleasure. As the Zohar says, the Hebrew word for “taste” – tam – also means “reason.” Don’t let temptations of the body blind you to the truths that come from your higher intellect.
The difference between bread and matzah is time: if you let even flour and cold water sit for eighteen minutes, it will begin to ferment. Matzah was hurried because the Israelites had to stay small in the night. So they ate humble bread while the terrible tenth plague, the slaying of the first born, passed over. Then they had to hurry because the next morning they were rushing out of Egypt. They made and ate matzah a second time. Rush towards redemption. Yearn for freedom.
The difference between bread and matzah is we eat bread three times a day through the year, but “on this night, only matzah.” Beware enslavement to routine habits or desires.
Matzah is bread without spirit, its golem. Beware idolatries, worshiping things that are mere flat objects, empty of true dimension or inner meaning, else you will become like matzah, flat and de-spirited.
Many hosts answer the invitation to interpret by writing fashionable causes du jour into their Haggadah. Fifty years ago, the spirit of Passover helped fuel the civil rights movement. Now, almost every homegrown haggadah now includes passages about Martin Luther King, or genocide and slavery in other regions of the world, or calls for equality for transgender people and an end to the oppression of animals by us Pesach carnivores, or analogies between an unpopular president and pharaoh, or even, chas v’chalilah, insanely misguided pleas for Israel to end its so-called apartheid.
For that reason, the sermons that move me the most are not political but ones that drive to mystical implications. Matzah reminds us that God himself intervened in nature and time to free us. Because in Egypt we had only flattened slave-perception, we, and the world, had to witness His miracles firsthand to be convinced. At other times, He works only through nature, quietly if ubiquitously. In the kabbalistic tradition, matzah represents the absence of this true knowledge and understanding of God.
Metaphysics in the physics of matzah
It was my idolatrous love of sushi that drove me to look at the physics of matzah.
This year, I thought we would fulfill the theme of liberation by “going Sephardi”: giving ourselves permission to eat rice on Passover. Since Talmudic time, all Jews who follow strict practices have agreed to avoid the five grains that expand when cooked – oats, barley, spelt, wheat and rye. But a schism arose in the last five centuries between the Ashkenazi, Jews of Europe and the Sephardi, Jews descended from exiles from the Spanish Inquisition (and then most Arab countries in Northern Africa and the East). Maybe because they lived where the weather made them grumpier, Ashkenazi Jews constructed the anti-inflation rule strictly and also forbad lentils, beans, corn, and rice. The Sephardi continue to enjoy them. I voted for rice, largely because I had a fantasy about kosher for Passover sushi.
I lost. But to defend my unpopular position, I was driven to science to try to find out what exactly caused the dread “inflation.” What I discovered didn’t help me win my case, but it opened up an incredible vista about the difference between bread and matzah incarnated in the biophysics of yeast.
Matzah and bread both are essentially wheat flour and water. Outside the seder, on Passover we can add eggs and salt for flavor, and some matzahs that are KLP (kosher for Passover) even include oil, honey, juice, or even wine, as long as they don’t make the dough rise. But during the seder proper, we are supposed to eat only “poor matzah”: flour and water. To make bread, you need yeast.
Humans recognized and harnessed the magical properties of yeast even before they could write. Yeast makes flour and water into bread. It also makes grapes into wine. It seems to add life to inert foodstuffs, transforming them magically into something else alive. Grape juice is just a soft drink. But wine is literally a spirit. A cracker is a good delivery platform for dip, but bread is the staff of life itself. By ingesting wine and bread, we take some of that magic into us. Bread sates. Wine leavens our spirit. It’s no wonder bread and wine were worshiped by the ancients and are central to many religious rituals.
Though the technology of yeast has been perfected, the science of yeast still holds mysteries and surprises. To put it another way, we know the mechanics of how yeast work down to the molecular level, but we’re not completely sure how it performs its magic.
The quantum physics of yeast
Yeast is a single-celled living creature. When we let these critters feed on their favorite food, sugar or anything that contains sugar or carbohydrates, they digest it into sugar’s components: energy, alcohol, carbon dioxide, and some residue molecules that add flavors. The process the ancients observed was bubbling, rising fermentation. When we bake bread, the heat evaporates alcohol produced by the yeast into gas bubbles that expand and burst, contained by the sticky dough. This gives bread its texture. In the cooler processing of wine (and beer), the alcohol is completely contained in the liquid for our pleasure.
All this you probably learned in high school chemistry as an example of enzymatic activity. But what they didn’t teach us, because chemistry isn’t etymology, is that “enzyme” is just the Greek for “in yeast.” And what you didn’t learn, because chemistry didn’t know, is how yeast, or enzymes, are the gateway between the living and the inert, literally life and death.
The new science of quantum biology has started to answer the question of how yeast performs this magic.
Yeast is the ur-type of all enzymes. Enzymes are present in all living things, in every living cell, and in every process that sustains life: digestion, neural action, making new cells and repairing old ones (growth and healing), reproduction, and so on. There is an eternal philosophical battle between materialists and vitalists. Materialists believe the universe and everything in it, including humans and human consciousness, is a vast machine. It is made up only of physical things and the physical processes or forces between them. Vitalists argue that there is a meta-physical force in the universe that animates all life, a force that cannot be reduced to mechanical explanations. Human consciousness particularly illustrates the problem and limitation of materialism. Fundamentalist materialists argue that everything can be explained ultimately, by self-consistent systems of reason, like logic or mathematics. Religious vitalists argue that the metaphysical force is divine.
Although yeast is a living thing, enzymes have until recently seemed to be purely chemical machines. In the debate between materialists and vitalists, enzymes have been the best proof for the materialist view of life. They seem to explain how life is introduced into inert matter without resort to non-mechanistic explanations. Until now.
It turns out that enzymes require quantum effects to do their work, and quantum mechanics defies the materialist view of the cosmos. At its best, quantum mechanics defies logic, though we’ve learned to use them in MRIs and computer chips. At its worst, every quantum process requires an aware being to watch it work in order for it to be real.
I know to most of you unfamiliar with it this claim for quantum mechanics seems just weird. There’s no way to explain any quantum process without over-simplifying it or resorting to analogies which dangerously distort its actual, full-on weirdness. Many have tried and some have succeeded. (See a very spare reading list at the end of this blog of some I think do the best job.) Let’s just say the quantum is profoundly counter-intuitive. But here are a few of the weird facts that you will need to know as we continue with our discussion of matzah. I leave it to you to discover whether you buy any of it yourself:
Sub-atomic entities behave like both waves of energy and particles at the same time.
A sub-atomic entity isn’t in any one specific place until you observe it. Then it seems to settle on one. (Uncertainty)
A single sub-atomic particle can be in two places at once. But if you affect one, its other self will react, even if they are separated by millions of miles. (Superposition)
They can pass through otherwise impassible-seeming barriers (quantum tunneling) and “travel” faster than the speed of light.
When a subatomic particle is observed or measured, it “collapses” from its various possible quantum states into one state. Ie, it stops behaving quantumly and starts behaving classically. (Measurement)
To understand the quantum theology of matzah, the last aspect is the most important. Until now, biologists have been fairly content to leave the weirdness of the quantum world among physicists. They assumed there was an unbreachable barrier between the sub-atomic world of quantum weirdness and the macroscopic world of biology obedient to classical laws of physics. Thankfully (they believed) micro monkey business collapsed when it poked its head up into an organism because the complexity of the organism automatically “measured” (observed) it (though no one specified how). They now seem to be really wrong. It’s uncomfortable.
Resurrected by water, living yeast seems to make the inert come alive. Yeast works enzymatically to ferment the sugars in flour. It explodes the flat mound of dough and makes it rise as little bubbles of alcohol explode inside. It adds tastes by creating new molecules. But what was once thought to be a classical, if incompletely understood, mechanical process (catalysis) we now know requires quantum tunneling.
Quantum tunneling in yeast
Here’s the technical explanation: an enzyme in yeast takes a positively charged sub-atomic particle, the proton from the alcohol it has created, and transfers it to another molecule. This new molecule, with the addition of its extra proton, now has a positive charge. Like a magnet, it now attracts molecules carrying a negatively charged particle, the electron. So the new molecule the yeast created (called nicotinamide alcohol dehydrase or NADH) becomes a very effective carrier and releasor of electrons. With NADH, the ingredients can now perform their actions very quickly and efficiently. It’s like the brew now has an electric current running through it, with electrons able to hitch a ride and jump off when a chemical reaction needs an extra jolt of energy to make it happen.
So far so good. This is all safe, mechanical chemistry.
As it turns out, though, the speed at which electrons get transferred from alcohol to NAD+ to make NADH cannot be explained by classical chemistry. On the other hand, quantum tunneling, number three on our list of weird quantum effects above, can. Again, at the risk of over-simplifying, a subatomic particle can help an electron travel across barriers instantaneously by using its superpower of quantum tunneling. As this effect occurs among millions of molecules in the dough, it speeds up the process enough for biologists to say it must be involved. 
This neat explanation of the quantum role in enzymatic action leaves one huge mystery, though: In order for the transport of the electron to occur, it can’t be just a probability, and in order for it to be more than a probability, it has to be observed or measured. The probabilistic quantum behavior – the electron can be here or there and therefore nowhere at all, really – has to become classical behavior. I see it now. Until now, biologists, scientists and other materialists have maintained that the macroscopic bulk of the organism in which the quantum action occurs collapses any quantum craziness. I.e., the fact of the organism itself performs the “observing.” But that argument no longer holds water and even seems like a tautology, fabulous circular reasoning, because enzymes involve quantum action. Enzymes, and the quantum, is ubiquitous in every process of every cell in an organism. In fact, it seems to be the essence of life itself.
“Enzymes have made and unmade every living cell that lives or has ever lived. Enzymes are as close as anything to the vital factors of life. …. [T]he discovery that enzymes work by promoting the dematerialization of particles from one point in space and their instantaneous materialization in another provides us with a novel insight into the mystery of life.”
– Johnjoe McFadden, Jim Al-Khalili, Life on the Edge: The Coming of Age of Quantum Biology (Broadway Books, Jul 26, 2016) p. 97
There’s simply too much quantum funny business going on everywhere in a living being to say one part of the organism is classical and collapses the other part that’s quantum.
Another way materialists banish the quantum: the Many Worlds Hypothesis
Scientists have resolved the measurement problem another way. They hypothesize that instead of collapsing the quantum into the classical through observation, every time a quantum event collapses into a classical one, other universes are spawned. All the other probabilities that didn’t occur here does occur there, in these new universes.
This hypothesis is mathematically satisfying and sidesteps any suggestion of metaphysics. But there are a virtually infinite set of quantum events occurring everywhere at every instant everywhere in an organism, let alone the whole universe. Each of them would create an incalculable set of alternate universes. You do the dizzying math. Or alternatively, ask yourself: Which is the more ridiculous vision of the cosmos? This vision creates an even crazier and more incomprehensible cosmos than the one we have.
But who knows? That’s what they said about quantum theory in the twentieth century. And that’s what most well-educated, modern, rational sophisticated people say about God.
Quantum theology of matzah
Quantum theology is a term used by a few but growing number of theologians and mystics. Many of their essays and speculations are plagued by vagueness, weak understanding of science, and an over-heated, optimistic leap into the irrational analogies between quantum science and mysticism to prove God’s existence. Their “proofs” often require taking analogous-sounding mysteries as equivalents. Quantum theology is largely the provenance of well-educated fundamentalists.
The case of yeast is different. In this dance between the material and the vital, between science and faith, the science leads us to conclude something mystical is happening in bread that doesn’t occur in matzah. That matzah has been promising something like this is lurking in its layers of meaning is a deligthful coincidence. Even on its own terms, though, the new science of quantum biology shows quite specifically how the process of life itself depends on quantum action. In every possible process where life is created or sustained, enzymatic action is involved. And with quantum action comes the requirement that someone or something is observing the process. The nose of the quantum camel has entered the tent of biology, but it was summoned by the biology. In fact, the tent is the camel. Something or someone has to be observing omnipresent quantum events in enzymes to make them operative in life. Someone or something has to be operating life. Omnisciently.
Couple the biophysics with the metaphysics of the matzah and we get a powerful sermon. Matzah is bread without attention, perhaps without the attention of a Cosmic Consciousness. It represents enslavement to inert material. It is both literally the bread of affliction, the food of slaves, and symbolically life without redemption from our inner Egypt, the body without a soul. Matzah invokes a God who redeemed the Children of Israel from slavery more than three thousand years ago and Who continues to operate the universe today by attending to its every quantum event. He is an incomprehensibly vast God Who observes every infinitesimal event, all the infinite infinitesimal events that occur every instant to sustain each living cell of each living organism. This is a God that watches everything actively. This God expands and unfolds His Cognizance as much as the universe imagined by the Many Worlds Hypothesis multiplies infinitely bubbling alternatives, only this God gives it life and an elegant unity. I like this God and this idea of Him.
One of the sermons on matzah is a kabbalistic one. Isaac Luria, the 16th century mystic of Safed, explains that the three matzahs on the seder plate represent Knowledge, Understanding, and Wisdom. Matzah invites us to stretch our scientific wisdom to its fullest extent beyond enslavement to our preconceptions. Matzah also contains a sermon about the liberation of science from its prejudices.
 Prof. Judith Klinman of UC Berkeley first suggested that quantum processes were involved in the enzymatic action in 1987. She has more recently found experimental evidence for it. See, for instance,Judith P. Klinman and Amnon Kohen, “Hydrogen Tunneling Links Protein Dynamics to Enzyme Catalysis,”Annual Rev Biochem. 2013; 82: 471-496.
So a Jewish carpenter gets stranded on a desert island for 20 years. He is finally rescued, but before he’s taken off the island, he insists on taking the captain on a tour of his handiwork. He’s built a whole town by hand, you see: homes, a butcher, a baker, a tailor. The captain is amazed, and then he sees two magnificent structures on the hill overlooking the town,
“What are those two buildings?” he asks .
“Oh, those?” the carpenter says dismissively. “They’re two synagogues.”
“Two synagogues?” asks the captain in amazement. “Why’d you build two synagogues?”
“See the one on the right? That’s the one I won’t go to.”
Does science invoke God?
If you’ve ever been a member of a congregation that is about to split over irreconcilable differences of theological opinion, you know how true the joke feels. But I tell it to mock the division between two faiths, science and religion. As the rift between the two has calcified, it’s looking more ridiculous and dispensable, like two old enemies who need to conjure each other in order to keep some militant vitality alive in their feud, Big Endians and Little Endians.
If we wouldn’t get excommunicated either from the Church of Science or the Academy of Belief, would we ask, “Is science a proper way to worship God?” If we wouldn’t be declared a heretic, would our church permit us to grant truth to all of science’s glory?
In the twenty-first century, an alert and dispassionate science should be able to admit that physics requires a metaphysical assumption about the way the universe works. Logic is a faith in its own, and believing in a universe that can be completely explained by logic requires a spiritual leap and even a certain blindness, especially after Kurt Gödel proved the limits of logic. On the other side of the limitations of reason lies the inexplicably unreasonable efficacy of mathematics in explaining the world (as Eugene Wigner noted in 1960), the crazy serendipity of, for instance, Planck’s Constant.
At the same time, to just say science explains what it can and let God be responsible for the rest – let God take the hindmost – is a losing gambit. It protects apparently shrinking territory.
I propose here that God has positive explanatory power in both science and religion. Quantum mechanics as we increasingly understand it almost demands the invention of some God-like Consciousness. And a vital faith, especially an organized and systematic monotheistic faith in God, should embrace our evolving, unfolding, scientific knowledge of the universe as Divine.
Muslims and Jews further possess mystical customs — Islamic Sufism and Jewish Kabbalah — that are so close to one another that the presumption of mutual influence is inescapable. Yet the transmission of these spiritual doctrines and practices between them is still historically mysterious.
The moral of the story is that anyone who is tempted to see support for theological constructions of the universe in quantum physics should tread carefully. That hasn’t stopped speculations by amateur physicists but professional mystics, and professional physicists but amateur theologians, to leap to the hope that quantum cosmology proves there is a God. Fritjof Capra’s The Tao of Physics (1984), Atoms, Snowflakes and God: The Convergence of Science and Religion(J.L. Hitchcock, 1982), The Science of God (G. Schroeder, 1998) are just three of many. There’s even an ideological rant with the title Quantum Theology (Diarmuid O’Murchu, 1987).
The God I mean isn’t a Christian God. He isn’t a Newtonian God. He isn’t a Cartesian God. He’s not the Great Clockmaker in the sky. The cartoon Western concept of God as static, perfectly rational, immutable, unitary, immortally consistent and knowable is inherited from overly-idealistic Greeks, from Plato and before him Pythagoras. They had a brilliant fetish for order and a gift for making sense. This Platonic ideal has had its splendid multi-millenial run. It gave us mathematics in all its elegance and the beautiful, aspirational dream of a rational universe that was smooth and simple and explicable and could be reduced to a Unified Answer.
Postmodern science, by contrast, calls for the non-Sense God of the Hebrews that Moses saw in the Non-burning Bush, the Dynamic Essence, forever unknowable, sometimes contradictory, receding, transcendental, yet mutable. Not One and Done, but always Becoming, involved in every aspect of the universe all the time. The grand project of our minds, the systematic quest for truth, is an expression of Divinity. A God needing interpretation as best we can by sixty-three volumes and centuries of commentary in the Talmud and the billions of words He has invited in the 1500 years since. The God that can be worshiped through science is an inconceivable God of Infinite Complexity, Abstraction, and Attentiveness Whom we can only strive to but never quite comprehend fully. This is the God who gave us the primitive alphabet for language in all its untranslatable ambiguity, not a reductive idolatrous god who gave us algebra and geometry and golden triangles and code as if the dazzling universe could be disambiguated in a cubicle. This God left clues as to the inter-connected nature of everything in everything waiting for us to enliven them with our gaze and imagination. In short, this is the God of Language, of a Holy Tongue, not Binary Code, an Author, not a programmer.
Metaphysics of the church of physics
Woody Allen said, “Love may be the answer. But while you’re waiting for the answer, sex poses some pretty good questions.” A Grand Unified Theory of Everything may be the answer, but while we’re waiting, quantum physics poses some pretty good questions, theological questions about the origin of life, the nature of mind, and the possibility that the universe collapses into this reality because Someone Impossibly Infinite to Imagine is observing every quantum event in the universe. The alternative is an equally inconceivable explanation: that every time a quantum probability wave collapses into reality, another universe is created, the so-called Multiverse Hypothesis.
There is now a serious discussion about the way quantum mechanics may be implicated with the biology of consciousness as well with the fabric of the universe. For instance, in an otherwise brilliant and lucid book, Life on the Edge: The Coming of Age of Quantum Biology (2014) Johnjoe McFadden and Jim Al-Khalidi show that quantum physics drives the biochemistry of photosynthesis, genetics, enzymes, smell, and perhaps even consciousness. This is transcendence, requiring the collapse of epistemological boundaries between macroscopic biology and sub-atomic quantum events. Yet, when the authors consider the possible role of quantum biology in how the mind arises from the brain or life from inorganic matter, they are quick to protest their orthodoxy by bracketing out any whiff of theology:
Can our new understanding of life [as having its source in quantum mechanics] replace the soul with a quantum vital spark? Many will regard the very posing of this question as suspect, pushing the bounds of conventional science beyond respectability and into the realms of pseudoscience and spirituality. That is not what we’re proposing here. Instead, we want to offer what we hope is an idea that might replace mystical and metaphyscial speculations with at least the grain of a scientific theory.” (p. 310)
It never occurs to these authors to consider the middle they have excluded, that the very “grain of a scientific theory” they are exploring in quantum biology is the essence of the mysticism they loathe. Of course, they can’t. They’d be excommunicated. Or at least, denied tenure. But let’s linger on this excluded middle. At the slippery, frothing interface between mind and matter, serious physicists who are quick to disavow any theology in their science end up sounding defensive, but not convincing. If we wouldn’t get kicked out of Church of Science, would we pose that pretty good theological question: Is life, the soul, a quantum process?
(1) Philip Clayton writes, “In this brief sketch of the history of Western metaphysics, we have seen that the problem of matter remains an unsolved conundrum. Although the problem was continually reformulated and redefined, every attempt to understand matter ends up focusing on the active principle of the intellect– that which makes understanding possible – rather than what was supposed to be understood, which was matter as qua [exactly that which is] non-mental. Again it is as if matter continually recedes from our grasp. One even wonders: could it be that matter is in essence that which cannot be understood, that which inevitably recedes from us as we approach it? Here one thinks of the notion of the transcendental signified” in the work of the influential French philosopher, Jacques Derrida. [1995b, 1998]. If the parallel indeed holds, matter is another name for what Derrida called la differánce, that which is always different from our formulations and which is always deferred into the future whenever we seek to understand it.” P. Clayton,”Unsolved Dilemmas,” in Information and the Nature of Reality: From Physics to Metaphysics. ed by Paul Davies and Niels Henrik Gregerson (Cambridge UP, 2010: pp. 50-51).
Of course, I believe that Derrida was an anti-theological Jewish mystic and prophet, who erected an entire philosophical system, preserved Jewish ways of knowing and discoursing, and even in part Jewish ethics, by substituting a very Jewish understanding of God with the idea of differánce, but that is another long story.
(2) Thomas Pynchon, that great epistemological jokester, quipped, “…excluded middles, they’re bad shit.” (The Crying of Lot 49). Oedipa Maas is hung up between the poles of deterministic logic and transcendence: “She had heard all about excluded middles; they were bad shit, to be avoided; and how had it ever happened here, with the chances once so good for diversity? For it was now like walking among matrices of a great digital computer, the zeroes and ones twinned above, hanging like balanced mobiles right and left, ahead, thick, maybe endless. Behind the hieroglyphic streets there would either be a transcendent meaning, or only the earth.”
