Speusippus

From Wikipedia, the free encyclopedia

For the Christian saint, see Speusippus, Eleusippus, and Melapsippus.

Speusippus (407 BC-339 BC) was an ancient Greek philosopher. Speusippus was Plato's nephew by his sister Potone.

After Plato's death, Speusippus inherited the Academy and remained its head for the next eight years. However, following a stroke, he passed the chair to Xenocrates. Unlike Plato, Speusippus required his students pay for their education.

Speusippus was noted for his debauchery and extravagance. Plato attempted to curb him, but without effect. He died either of suicide or a wasting disease. Upon his death, Aristotle acquired his library.

Speusippus held that it was impossible to know everything, without being aware of all other knowledge besides, in opposition to scepticism. Though it is said that Speusippus adhered to Plato's doctrines, according to Diogenes Laertius, he rejected the Platonic theory of forms.
