Full Idea

Intellect can abstract mathematical species from sensible matter, both individual and common. Yet it cannot abstract such species from common intelligible matter, but only from individual intelligible matter.

Gist of Idea

Mathematics can be abstracted from sensible matter, and from individual intelligible matter


Thomas Aquinas (Summa Theologicae [1265], Q85 Ad2)
