Abstract

In this paper I discuss Berkeley’s theories about vision, perception of distance, and the foundations of Geometry. I start with Locke’s answer to Molineaux’s problem and the criticisms Berkeley addressed to it. I explain the fundamentais of Berkeley’s theory about our cognitive shaping of the visual field and the type of connections that visual data establishes with data from the haptic field. I show how interesting are Berkeley’s conceptions for a phenomenology of perception, and, eventually, I carried some phenomenological evidence against Berkeley’s too much strict location of the idea of distance in the haptic field alone.
