Speusippus (407 BC-339 BC)

For Speusippus, the first cause of all beings cannot be a being itself (principle of alien causality). He divides philosophy into Dialectics, Ethics and Physics and insists that producing a complete definition requires identifying the differences which draw an object apart from the rest (genera and species). Speusippus regards Man as able to reach happiness (untroubledness) by means of rational control over his desires.
