Berkeley's theory of vision: Optical origins and ontological consequences George Berkeley. Giovanni Battista. Grandi , University of Windsor. In the present work Berkeley's theory of vision is considered in its historical origins, in its relation to Berkeley's general philosophical conceptions, and in its early reception. Berkeley's theory replaces an account of vision according to which distance and other spatial properties are deduced from elementary data through an unconscious geometric inference.

This account of vision in terms of "natural geometry" was first introduced by Descartes and Malebranche. Among Berkeley's immediate sources of knowledge of the geometric theory of perception, a key role was played by the treatise of dioptrics of William Molyneux, Dioptrica Nova. Berkeley's understanding of "natural geometry" relies closely on Molyneux's description of the mechanism of vision which avoids the complexities of the accounts of Descartes and Malebranche.

In the first chapter Berkeley's theory is presented by way of contrast with Molyneux's theory. In the second chapter I consider the relation between the theory of vision and immaterialism. In the final chapter I examine one of the first criticisms of Berkeley's theory, that which is found in William Porterfield's Treatise on the Eye.
