Who is arcesilas of cyrene?

Answer 1

Within a century of Plato's death his school had been completely transformed by Arcesilas, its head in the middle of the third century B.C.; he imported into it the denial of the possibility of knowledge that had been set up as a philosophical system by the Sceptic Pyrrho two generations before. Arcesilas was regarded as having refounded the school, which was no called the Second or New Academy. Arcesilas's work was carried further a century later by Carnrades, who employed his acute logic in demolishing the natural theology of the Stoics.
