Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

Summa Contra Gentiles

God's eternity vs created time. Aquinas defends the philosophical-theological compatibility of divine foreknowledge and human freedom developed at length in SCG I.66ff.

Space

Summa Contra Gentiles

Standard medieval cosmology. God omnipresent without being spatial; creatures finitely located.

Matter

Summa Contra Gentiles

Hylomorphic; created ex nihilo by God. SCG II is one of the most extensive discussions of creation in medieval philosophy.

Observer

Summa Contra Gentiles

The human person is body-soul composite, capable of natural knowledge of God through reason and supernatural knowledge through revelation. The beatific vision is the consummation of cognitive life.

Energy

Summa Contra Gentiles

Esse — the act of being — is the central energetic metaphysical category, sustained continuously by God.

Information

Summa Contra Gentiles

God's knowledge of creatures is the archetype; creatures participate in divine knowing. Personal information is conserved across death.

Internal Tensions

Where each work's argument pulls against itself.

Summa Contra Gentiles

The SCG's book IV depends on revelation, while books I–III claim philosophical autonomy. The relation between these two methods has been the central interpretive question — some Thomists (Gilson) read the natural-reason arguments as themselves theologically motivated; others (Maritain) defend their philosophical autonomy.
