I found a wonderful website this week: The Galilean Library. The site is a resource for people interested in the sciences and humanities, and in particular philosophy, history, literature, and history and philosophy of science. It includes a library of essays and interviews aimed at all levels, along with a discussion forum on such subjects as free will and the nature of courage. The philosophy section has an ongoing series of essays about philosophy, beginning with the question of what philosophy is and what it means to do philosophy, and moving on to specific areas of philosophy. Great material here for high school classes!
