summaryVisual processing is usually thought to proceed from low level analysis (edges and lines) to high level analysis (shapes and objects) in a hierarchical and feedforward manner. This view is also at the very heart of many philosophical and computational theories captured, for example, by the computer metaphor of the brain. To the contrary, I will show, first, how shape perception and good Gestalt determine low level vision. Second, I will show how the mind constitutes itself through perceptual learning by mental imagery and other top-down factors such as attention. Third, I will show that visual processing is ill-posed and, for this reason, necessitates the involvement top-down factors. Finally, I will discuss implications for epistemology and theories of truth.
