Some of the best philosophers in the world gather in surprising places--preschools and playgrounds. They debate questions about metaphysics and morality, even though they've never heard the words and perhaps can't even tie their shoes. They're kids. And as Scott Hershovitz shows in this delightful debut, they're astoundingly good philosophers. Following an agenda set by his 2 young sons, Rex and Hank, Hershovitz takes us on a fun romp through classic and contemporary philosophy, powered by questions like, Does Hank have the right to drink soda? When is it okay to swear? and, Does the number six exist? Hershovitz and his boys take on more weighty issues too. They explore punishment, authority, sex, gender, race, the nature of truth and knowledge, and the existence of God. Along the way, they get help from professional philosophers, famous and obscure. And they show that all of us have a lot to learn from listening to kids--and thinking with them.
