Descartes is perhaps best known for his statement, "Cogito, ergo sum," the cornerstone of his metaphysics. But he did not intend the metaphysics to stand apart from his scientific work, which included important investigations into physics, mathematics, and optics.

And what role might adopting a sceptical outlook play in leading an intellectually virtuous life?

All societies are violent and all individuals have the capacity for violence. However, not all societies and not all individuals are equally violent, and nor does violence exist with the same intensity across cultures.
