Perception is the foundation of knowledge and the source of everything we know. Epistemology is the branch of philosophy that studies the nature, acquisition, and validation of knowledge. To make the connection between perception and the rest of our knowledge—for example, to form concepts—we need a set of guidelines to understand the nature of this integration. The epistemology of perception fills this gap. Recorded in June 1985
In Part 1 of this talk Dr. David Kelley tackles the questions that skeptics have used to challenge the reliability of the senses—such as illusions and other specific phenomena—by distinguishing between what we perceive and how we perceive, between the object and the form in which we are aware of the object.
Part 2 takes up another important distinction in epistemology, the distinction between sensation and perception.

David Kelley is the founder of The Atlas Society. A professional philosopher, teacher, and best-selling author, he has been a leading proponent of Objectivism for more than 25 years.
David Kelley founded The Atlas Society (TAS) in 1990 and served as Executive Director through 2016. In addition, as Chief Intellectual Officer, he was responsible for overseeing the content produced by the organization: articles, videos, talks at conferences, etc.. Retired from TAS in 2018, he remains active in TAS projects and continues to serve on the Board of Trustees.
Kelley is a professional philosopher, teacher, and writer. After earning a Ph.D. in philosophy from Princeton University in 1975, he joined the philosophy department of Vassar College, where he taught a wide variety of courses at all levels. He has also taught philosophy at Brandeis University and lectured frequently on other campuses.
Kelley's philosophical writings include original works in ethics, epistemology, and politics, many of them developing Objectivist ideas in new depth and new directions. He is the author of The Evidence of the Senses, a treatise in epistemology; Truth and Toleration in Objectivism, on issues in the Objectivist movement; Unrugged Individualism: The Selfish Basis of Benevolence; and The Art of Reasoning, a widely used textbook for introductory logic, now in its 5th edition.
Kelley has lectured and published on a wide range of political and cultural topics. His articles on social issues and public policy have appeared in Harpers, The Sciences, Reason, Harvard Business Review, The Freeman, On Principle, and elsewhere. During the 1980s, he wrote frequently for Barrons Financial and Business Magazine on such issues as egalitarianism, immigration, minimum wage laws, and Social Security.
His book A Life of One’s Own: Individual Rights and the Welfare State is a critique of the moral premises of the welfare state and defense of private alternatives that preserve individual autonomy, responsibility, and dignity. His appearance on John Stossel’s ABC/TV special "Greed" in 1998 stirred a national debate on the ethics of capitalism.
An internationally-recognized expert on Objectivism, he has lectured widely on Ayn Rand, her ideas, and her works. He was a consultant to the film adaptation of Atlas Shrugged, and editor of Atlas Shrugged: The Novel, the Films, the Philosophy.
