This is a website compiled by Jim Walker. He lists a number of individuals that he considers free thinkers because they have they rejected a dangerous commonly held belief (or several of them) in favor of rational thinking at some time or other. He dedicates the site to those freethinkers, which represent his favorites (during their periods of freethinking), not all freethinkers (for example, he didn’t include Voltaire or Ayn Rand). He does provide an extended list of freethinkers at the end of the site.
