Philosophers
100 philosophers. People known mainly for work outside philosophy (science, writing, medicine, reform) who are widely recognised for how they reasoned, tested claims or exposed errors. Philosophers are people whose main work is philosophy itself, as studied in philosophy courses and the Stanford Encyclopedia of Philosophy. See the Great Critical Thinkers.
