Socrates

Socrates Socrates was a philosopher in the classical era, who was born in 469B.C, and once speculated that no one knew anything, including him, but by knowing that he knew nothing, he knew something. Socrates, among other things, was a champion doubter, perhaps of all time. He doubted everything, he doubted that anyone actually knew anything, he doubted himself and others, and he even doubted democracy! One of Socrates greatest achievements was having Plato as a student, who became one of the greatest ancient mathematicians of all time. Socrates was executed for impiety (not believing in the gods of the state) in 399 B.C.
