Branch of philosophy that studies the nature of knowledge


Ayn Rand and Objectivism - Epistemology: The theory of knowledge, Full Context
Summarises the key concepts of objectivist epistemology, contrasting them with other philosophical views
"A handful of other philosophies besides Objectivism have defended perceptual realism, the theory that we directly perceive things in the external world. But Objectivism is the first philosophy to identify the connection between the primacy of consciousness and the various false theories of the relation between consciousness and existence, among them: representationalism, phenomenalism, idealism, the 'sense-data' theory, and others."

Ayn Rand on Aristotle, by George H. Smith, 4 Mar 2016
Examines Rand's appreciative view of Aristotle based on his epistemological theories while disregarding his comments on slavery, racism and coercive government laws
"Aristotle's 'moderate realism' (to use the conventional label) was essentially correct, according to Rand, so it follows that Aristotle's influence must have been good, whereas the irrational epistemology of Plato (and, later, Kant) must have been bad. As Rand wrote in a letter (17 April, 1948), 'the crucial difference between Plato and Aristotle lies in their respective Theories of Knowledge and in their views on the nature of reality. That is the root. Their ethics, politics, etc., are the consequences.'"
Epistemology and Politics: Ayn Rand's Cultural Commentary, by David Kelley, Navigator, Dec 2004
Discusses Rand's 1960 essay "Faith and Force: The Destroyers of the Modern World" and the continued currency of her writings
"... reason is an objective means of knowledge; it relies on observation and evidence, with observable reality as the ultimate point of reference. So, when people rely on reason they can interact and resolve conflicts by discussion, persuasion, and debate—that is, by voluntary means. ... If people derive their conclusions from ineffable intuitions or by methods that only they know how to apply, ... [t]hat leaves force as the only method of 'persuasion' ..."

Herbert Spencer's Theory of Causation [PDF], by George H. Smith, The Journal of Libertarian Studies, 1981
Discusses Spencer's epistemology, his views on causation and how it affects social interactions, concluding with his ethical theory and concept of justice
"Time and again Spencer appears to confuse epistemology with psychology. By showing what a person is compelled to believe psychologically, Spencer infers that such beliefs enjoy epistemological validity. This is no oversight or slip on Spencer's part; it is a deliberate method employed throughout his epistemology. ... Here we have the merger of epistemology and psychology. Spencer's ultimate criterion of certitude is a psychological test."
