David Kelley (born June 23, 1949) is an American philosopher. He is a professed Objectivist, though his position that Objectivism can be revised and influenced by other schools of thought has prompted disagreements with other Objectivists. Kelley is also an author of several books on philosophy and the founder of The Atlas Society, an institution he established in 1990 after permanently dissociating with Leonard Peikoff and the Ayn Rand Institute.
