Rebecca Goldstein says some of her best friends are “philosophy jeerers,” convinced that anything philosophers can do, scientists can do better. She begs to differ, and offers the grandaddy of Western philosophy as exhibit A. 21st-century America has a surprising amount in common with Athens c. 400 BCE, Rebecca says, and Plato still has a thing or two to teach us moderns. She shows how well the 2,400-year-old-man has aged by transporting him to our own times in her new book “Plato at the Googleplex: Why Philosophy Won't go Away.” Rebecca and I talked about the world of the ancient Greeks, the death of Socrates, the relevance of Plato and what philosophy is good for.
