How Substances Can Be Good In Virtue of Their Existence Without Being Absolute Goods

Overview

The question this short tractate answers is a genuine puzzle, and Boethius poses it exactly: how can created things be good simply by existing, when goodness itself is God, and they plainly are not God? To answer it he does something unusual for a theological piece — he begins by laying down a set of axioms, common notions he asks the reader to grant as one grants them in geometry, and reasons from them step by step. The resolution turns on a distinction he draws sharply: the first good is good through its own being, while everything else is good by participation, good because its very existence flows from that first good and would be nothing without it. The method — theology conducted as a chain of proofs from stated axioms — mattered as much as the conclusion. Thomas Aquinas thought the tractate worth a full commentary of his own, taking up its problem seven centuries later and pushing the analysis further.

Key concepts

What puzzle does this tractate set out to solve?

How created things can be good simply by existing, when goodness itself is God and they are not God. If a thing is good just by being, and to be good is to be God, then each thing would seem to be God, which is absurd. Boethius poses the problem sharply and devotes the piece to resolving it without either denying creatures their goodness or making them divine.

What is the difference between the first good and other goods?

The first good, God, is good through its own being; its goodness and its existence are one. Everything else is good by participation: a created thing is good because its very existence derives from that first good and would be nothing apart from it. So creatures are genuinely good, but their goodness is received and dependent, never their own in the way God's is.

Why does Boethius argue from axioms like a geometer?

He opens by laying down common notions, self-evident principles he asks the reader to grant just as one grants axioms in geometry, and then reasons from them step by step to his conclusion. It is an unusual method for a theological work, and the point is rigour: a demonstration built from stated first principles rather than from scripture or authority. The method proved as influential as the conclusion.

Why is this tractate important despite its brevity?

It is the most purely philosophical of Boethius's theological pieces, arguing from reason alone rather than revelation, and its account of goodness by participation fed directly into medieval metaphysics. Its importance is measured by its readers: Thomas Aquinas took up its problem seven centuries later and wrote a full commentary on it, pushing the analysis of participation and being further still.

Boethius poses the puzzle sharply: if a thing is good merely by existing, and goodness itself is God, each existing thing would seem to be God, which is absurd. Unusually for a theological piece, he lays down common notions, axioms he asks the reader to grant as in geometry, and reasons step by step. The resolution turns on a distinction. The first good is good through its own being; everything else is good by participation, good because its existence flows from that first good, and nothing without it. The method mattered as much as the answer, and Aquinas thought it worth a full commentary of his own.
