The Periodic Table of the Human Elements

Every AI speaks to you from an idea of what you are. In most systems that idea was never chosen — it accumulated, from training data, product decisions, and engagement metrics, into something thin: a user, a set of preferences, a source of prompts, a problem to be optimized. It works. It is also wrong, and you can feel it in the answers.

This table is the alternative: the words that define a human being, defined carefully, in the classical philosophical tradition — Aristotle, Boethius, Aquinas — by reason, in plain language, for anyone who wants to check the reasoning. That includes the oldest claim of all — that a human being is a creature, created by God — which Aquinas argues philosophically, as creation: the emanation of all being from the universal cause, God (Summa Theologiae I, qq. 44–45).

These definitions stand or fall by reason; none asks to be believed on authority. But they are not traditionless. In their selection and synthesis, they reflect the Judeo-Christian understanding of the human being, in conversation with classical philosophy: a creature endowed with inviolable dignity and ordered toward truth, goodness, and love.

The Greeks used one word, stoicheion, for both an element and a letter of the alphabet — letters were, quite literally, the elements from which everything written is built. These words — the elements of the human being — work the same way. They are the elements from which an understanding of a person is built.

God, the Creator. One thing stands behind the whole table and is not in it: God, the Creator. A human being is not self-made; every element below describes someone whose existence is received.

Reading

How to read the table

Each element has a number, and the number is a promise: no word is used before it has been defined. The number is an address in two parts: the hundreds name the column — the 100s are Foundations, the 500s the Powers — and the rest gives the element's place within it. The gaps are deliberate: a new element takes the next free number at the foot of its column, and nothing already numbered ever moves. The columns are families: each column groups elements of a similar kind — foundations, constitution, finitude, transcendentals, powers, relationship, action, ends. Read down a column, then move to the next. An element may build on anything above it in its own column, and on anything in the columns to its left — never on what comes below or to the right. So person — element 200, an individual substance of a rational nature — rests on the foundations at its left; dignity follows from person; and freedom — element 502 — follows from Aquinas's “dominion over his own actions,” a clause planted in person (200) and harvested there. After Constitution stands Finitude — limit, need, vulnerability, and mortality: the bounded shape of a creature, within which every power is exercised. Between Constitution and Powers stands a column of a different kind — the Transcendentals: truth, goodness, and beauty are not parts of a person or powers of a person, but the horizons every power aims at. Reason aims at truth, freedom and desire at goodness, and the heart is awakened by beauty. The Relationship column runs its full course within itself: relationship (600) — the fact that no person is complete alone — its act in love (601), willing the good of the other, and its fruit in communion (602), where love that endures becomes a shared life.

The table grows downwards: as new elements are defined, they take their place at the foot of their family column. Read in order, the table is one argument. Read any cell on its own, and it still stands — but check its number and its column, and you will know exactly which earlier words it rests on.

Caution

A necessary caution

A person is not a compound.

Nobody is assembled from these elements and nobody can be taken apart into them — the last element in the table is mystery, and it is there on purpose. These are the simplest terms from which understanding of a human being is built. The human being always exceeds the table.
