Single Idea 20906

[filed under theme 8. Modes of Existence / D. Universals / 6. Platonic Forms / a. Platonic Forms ]

Full Idea

The Platonists, on the basis of purely logical arguments, posit the existence of an indivisible 'triangle in itself'.

Gist of Idea

Platonists argue for the indivisible triangle-in-itself

Source

report of Plato (works [c.375 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 316a15

Book Ref

Democritus: 'Early Greek Phil VII: Democritus', ed/tr. Laks,A/Most,G [Harvard Loeb 2016], p.103

A Reaction

A helpful confirmation that geometrical figures really are among the Forms (bearing in mind that numbers are not, because they contain one another). What shape is the Form of the triangle?
