The American Philosophical Association (or APA for short) is a group of people who are interested in learning and talking about philosophy. Philosophy is all about trying to understand the world around us and answer questions like "What is truth?" and "How should we live?"
The American Philosophical Association meets regularly and publishes books, journals and newsletters about what they learn. These meetings are a way for different people with different views to get together, talk, and learn from one another. They also offer awards and scholarships to people who have made important contributions to the field of philosophy.
