Andrew Chapman, a philosophy graduate student at University of Colorado, has started a website called 1000-Word Philosophy, a collection of introductory philosophy essays, each 1000 words or less. From the site’s about page:
Professional philosophy can seem abstract, esoteric, and hyper-specialized. But we all ask and try to answer philosophical questions myriad times daily—philosophy is the purview not just of the expert, but of all thoughtful people. Our goal in writing and sharing these essays is to provide high-quality introductions to great philosophical questions and debates. We hope that philosophers and non-philosophers alike will benefit from perusing these essays. Our authors generally provide references or sources for more information for readers whose interest is piqued by a particular topic or debate.
tl;dr – philosophy for a world in which tl;dr is a thing. (not necessarily a bad thing, btw.)
