One work by this thinker 
One work by this thinker contains the section "On Slavery" and argues that that freedom from absolute, arbitrary power is necessary for a man's preservation. This philosopher used the inability of people to justly reconcile differing faiths as a justification for tolerance in one of his works, which amusingly excepts atheism. In a better known work, this author of (*) A Letter Concerning Toleration argued that people come to own property by mixing their labor with natural resources and also submitted that people have the right to revolt against a government that denies them the basic rights of "life, liberty, and property." For 10 points, name this philosopher who wrote Two Treatises on Government as well as An Essay Concerning Human Understanding.
