How can school education best bring about moral improvement? Socrates believed that the unexamined life was not worth living and that the philosophical examination of life required a collaborative inquiry. Today, our society relegates responsibility for values to the personal sphere rather than the social one. I will argue that, overall, we need to give more emphasis to collaboration and inquiry rather than pitting students against each other and focusing too much attention on "teaching that" instead of "teaching how". I will argue that we need to include philosophy in the curriculum throughout the school years, and teach it through a collaborative inquiry which enables children to participate in an open society subject to reason. Such collaborative inquiry integrates personal responsibility with social values more effectively than sectarian and didactic religious education.
