This site aims to gather in one place links to all the most useful critical thinking resources on the web. Links are added to the site on a regular basis, as additional resources come to my attention.
Some links appear on multiple pages.
My general strategy has been to let the resources describe themselves, by quoting some relevant part of the linked page. This is a lot less effort than drafting an informative annotation of my own, if sometimes less useful. The site is biased towards university or college-level critical thinking, and also towards informal reasoning, since these are my own starting points. However I've tried to be ecumenical and to include anything of value, including resources relevant to K-12 education. This site started out as a resource for students in my own informal reasoning classes, but I am making it available to the world at large as a kind of public service.
