Meaning

Trigōnon is a triangle. The philosophical example distinguishes a particular triangle from triangle itself and from properties necessarily belonging to the figure.

Use in the book

The classification of cognition assigns images or participating instances to opinion, necessary geometrical properties to knowledge, and forms themselves to intellect. Triangle illustrates the sequence. The point is not merely that the same drawing can be looked at in several ways, but that different kinds of object are being distinguished.

Places to read

  1. I.48.6.7Particular triangle, necessary properties, and triangle itself illustrate kinds of cognition.

Translation in this edition
