The Tree of Knowledge as a Quantum-Mechanical Metaphor

To Mendel Almost three years ago, in December of 2019, I posted an essay, "The Tree of Knowledge as a Metaphor for Superposition of States and Heisenberg’s Uncertainty Principle." The manuscript of that essay contained an addendum with a short primer on the superposition of states in quantum mechanics and quantum-mechanical treatment of the primordial sin. It expressed the ideas of Maimonides about primordial sin in precise mathematical formulas proving the exact parallel between the fruit of the tree of knowledge of good and evil and a quantum eraser. Realizing that only people familiar with the formalism of quantum mechanics would understand that part of the essay and fearing losing my readers, I decided to omit the addendum entirely. However, the addendum is arguably the most interesting part of the essay, because it [...]

Curses, Blessings, and Semiconductors

Ki Tavo And it shall come to pass, when the Lord thy God shall bring thee into the land whither thou goest to possess it, that thou shalt set the blessing upon mount Gerizim, and the curse upon mount Ebal. (Deuteronomy 11:29)These shall stand upon mount Gerizim to bless the people, when ye are passed over the Jordan: Simeon, and Levi, and Judah, and Issachar, and Joseph, and Benjamin; and these shall stand upon mount Ebal for the curse: Reuben, Gad, and Asher, and Zebulun, Dan, and Naphtali. And the Levites shall speak, and say unto all the men of Israel with a loud voice: Cursed be the man that maketh a graven or molten image, an abomination unto the LORD, the work of the hands of the craftsman, and setteth it up [...]

The Temple as a Model of a Cell

Introduction Today, on Tisha B’Av—the ninth day of Av, this year commemorated on the tenth day of Av because the ninth is Shabbat, when mourning is forbidden—we mourn the destruction of the Holy Temple—Bet HaMikdash. This day commemorates the destruction of the First and Second Temples in Jerusalem. The First Temple was destroyed by the Babylonian king Nebuchadnezzar II, and Second Temple was destroyed by the Romans. Aside from its historical significance, why is the destruction of both Temples so tragic that it is mourned even today? What is the significance of the Temple in Jerusalem? The Temple was a building where kohanim-priests offered sacrifices. The sages state that the Temple was a source of life for the Jewish people.[1] This can be seen easily if we examine the parallels between the Temple and [...]

The Soul – Part IV. The Whole vs. the Parts

This is the fourth installment in the series of essays on the nature of the soul. The first three installments can be found here: What Is a Soul? I. The Spiritual vs. the Materia What Is a Soul? II. Anatomy of the Soul What is a Soul? III. The Many Souls of Man At the dawn of classical philosophy, there were two leading schools of thought: holism and atomism. Holism holds that a system (e.g., physical, chemical, biological, social) should be viewed as a whole rather than a collection of parts. Atomism, in contrast, holds the reductionist view that every system is a collection of parts, and the system can be known only by studying its parts. Holism[1] essentially stands for the proposition that the whole is greater than the sum of its [...]

What is a Soul? III. The Many Souls of Man

  …[H]e who tries to cure the soul, wishing to improve the moral qualities, must have a knowledge of the soul in its totality and its parts…Maimonides[1] Maimonides opens his introduction to The Ethics of the Fathers with this statement: Know that the human soul is one, but that it has many diversified activities. Some of these activities have, indeed, been called souls, which has given rise to the opinion that man has many souls, as was the belief of the physicians, with the result that the most distinguished of them states in the introduction of his book that there are three souls, the physical, the vital, and the psychical.[2] While Maimonides lists three souls—the physical (tiv’it), the vital (chiyunit), and the psychical (nefoshit)—he believes them to be aspects of one soul—“Know that [...]

Fill the Earth

And G‑d created man in His own image, in the image of G‑d created He him; male and female created He them. And G‑d blessed them; and G‑d said unto them: “Be fruitful, and multiply, and replenish the earth, and subdue it . . . .Genesis 1:28 G‑d created man, male and female, and commanded them to be fruitful and multiply, fill the earth, and subdue or conquer it. While the literal meaning of this verse is apparent—fill the earth with your progeny by procreating[1]—it begs a question. Specifically, the phrase “fill the earth” seems superfluous—wasn’t it enough to say “Be fruitful and multiply”? Indeed, the Hebrew word milupim[2] (“to multiply”) is etymologically related to the word mil’u[3] (“to fill”).[4] If humans were to multiply, as commanded by G‑d, they would naturally fill the earth. It seems [...]

The Cosmological Problem of Initial Conditions and the Universe of Tohu

Now the earth was unformed and void.Genesis 1:2 We have a big problem in cosmology: the problem of the initial conditions of the universe at the time of the Big Bang.[1] Before we can explain this problem, however, we need to review some basic concepts of thermodynamics. Thermodynamics developed by Boltzmann and others[2] described the behavior of gases and liquids and the transfer of heat. A key concept in thermodynamics is entropy. Entropy is a measure of disorder, of chaos. The second law of thermodynamics states that in an isolated system, entropy always increases with time. The second law of thermodynamics explains universal decay. And entropy is the measure of that decay.[3] Shining stars produce entropy. Stars collapsing into black holes produce entropy. Evaporating black holes produce entropy.[4] Entropy is increasing in the universe.[5] Let us [...]

A Wheel Within a Wheel

Now as I beheld the Chayot [living creatures], behold one Ophan [wheel] at the bottom hard by the living creatures, at the four faces thereof. The appearance of the Ophanim [wheels] and their work was like unto the colour of a beryl; and they four had one likeness; and their appearance and their work was as it were a wheel within a wheel. . . . As for their rings, they were high and they were dreadful; and they four had their rings full of eyes round about. Ezekiel 1:15–18 One of the most difficult theological questions is how Eternal G‑d relates to the world created by Him, the world that is always in flux. Indeed, the prophet Malachi says in the name of G‑d: For I the Eternal change not.Malachi 3:6 G‑d does [...]

Egyptian Exile as a Metaphor for Compactification in String Theory

And they made their lives bitter with hard service, in mortar and in brick…Exodus 1:14 On a literal level, the Egyptian exile (Galut Mitzrayim) is a story of the Jewish people’s enslavement in ancient Egypt, where they were forced to do hard labor making mortar and bricks, and building cities for the Pharaoh. On a deeper level, it is axiomatic in Jewish mysticism that suffering is usually a means to purify and rectify a sinner’s soul in this or past incarnation. It is also axiomatic that any sin damages the sinner’s soul and some supernal spiritual levels that obstruct the flow of the divine benefice into the world, impeding the blessing and, therefore, causing suffering to the sinner. Technically, it works as follows. When a sin committed below causes damage above, the resulting [...]
