More about the book
The twelve parts move from the good life and moral reasoning to freedom, faith, knowledge, and reality. We then turn to mind, language, and science before examining justice, social criticism, and art. You can follow the sequence or begin with a question that interests you.
The collection draws on several philosophical traditions, including ancient Greek, Indian, Chinese, Islamic, and modern European thought. It reflects the texts in this collection rather than attempting a complete history of philosophy. Difficult works have a place alongside more accessible starting points.
This book is in progress. Published chapters are free to read; the full table of contents also shows the chapters still being written. Four reading groups organize the larger project: Living Well, Belief and Reality, Mind, Meaning, and Science, and Society and Art.
