Characteristics of Forms
A general metaphysical and epistemological theory. Central to all of Plato’s thought, but nowhere systematically argued for. A theory of postulated abstract objects, deriving from the Socratic “What is X?” question, which presupposes that there is a single correct answer to the “What is X?” question.
1. The correct answer is not a matter of convention, of what we all (or most of us) think.
2. What makes such an answer correct: it is an accurate description of an independent entity, a Form.
3. Forms are thus mind-independent entities: their existence and nature is independent of our beliefs and judgments about them.
The Phaedo contains an extended description of the characteristics and functions of the forms:
Unchangeable
Eternal
Intelligible, not perceptible
Divine
Incorporeal (passim)
Causes of being (“The one over the many”)
Are unqualifiedly what their instances are only with qualification
Other dialogues fill out the picture: non-temporal; non-spatial; they do not become, they simply are.
Phaedo provides a good summary, listing all the attributes of Forms that souls also have: “divine, deathless, intelligible, uniform, indissoluble, always the same as itself.”
