Knowledge in perception and illusion - Richard Gregory

(For example, it was his letter that led Roosevelt to startthe Manhattan Project.)Among his many famous quotations is:"The search for truth is more precious than its possession."Einstein is most famous for his Special and General Theoriesof Relativity, but he should be considered the key pioneer ofQuantum Theory as well, drawing inferences from Planck's work thatno one else dared to draw.

For example, in a 1917 paper he anticipated the principle of the laser.

(Some even suspect that Descartes arranged the destructionof Pascal's lost .)And Descartes made numerous errors in his development ofphysics, perhaps even delaying science,with Huygens writing "in all of [Descartes'] physics,I find almost nothing to which I can subscribe as being correct."Even the historical importance of his mathematicsmay be somewhat exaggerated since others, e.g.

Richard L. Gregory was a British psychologist and Emeritus Professor of Neuropsychology at the University of Bristol. He was born in July 1923 in London, England and died in May of 2010 in Bristol. He believed that people use a process called Top-Down Processing to understand what we see. Top-Down processing is a process in which we use old knowledge to make sense of what we are perceiving. He believed that what we see is largely based on what we already know. Gregory argues that we create perceptual ideas when trying to recognise an object and that stored knowledge is used to fill in the missing pieces. However, using stored knowledge to make a perceptual hypothesis may not result in a correct hypothesis. The only problem with Gregory's theory is that some areas are left quite vague, like how we actually create these perceptual hypothesis or how we know when to accept that we have come to the right conclusion.
