Chiliagon
In
geometry, a
chiliagon (pronounced ) is a
polygon with
1000 sides. The measure of each
angle in a regular chiliagon is 179.64°.
René Descartes uses the chiliagon as an example in his
Sixth meditation to demonstrate the difference between pure intellection and imagination. He says that, on imagining a chiliagon, the image produced is not as clear and distinct as that which occurs on imagining a triangle, for example. It is also no different from that of a
myriagon. However, he does understand what a chiliagon is, just as he understands what a triangle is. Therefore, the imagination must in some way different from the mind, Descartes claims.
