Free will in antiquity
In Plato's Gorgias (and in the Protagoras 345c4-e6), Socrates argues that no one does wrong willingly, one of the most famous doctrines to be associated with him. When framed in modern (Western) terms, the implication is that it is ignorance, rather that free individual agency, that is responsible for morally wrong actions.
The unexamined life is not worth living
Socrates believed that philosophy – "the love of wisdom" – was the most important pursuit above all else. For some, he exemplifies more than anyone else in history the pursuit of wisdom through questioning and logical argument, by examining and by thinking. His 'examination' of life in this way spilled out into the lives of others, such that they began their own 'examination' of life, but he knew they would all die one day, as saying that a life without philosophy – an 'unexamined' life – was not worth living.
