Perception
In psychology and the cognitive sciences, perception is the process of acquiring, interpreting, selecting, and organizing sensory information. The word perception comes from the Latin perception-, percepio, , meaning “receiving, collecting, action of taking possession, apprehension with the mind or senses.” –OED.com. Methods of studying perception range from essentially biological or physiological approaches, through psychological approaches through the philosophy of mind and in empiricist epistemology, such as that of David Hume, John Locke, George Berkeley, or as in Merleau Ponty‘s affirmation of perception as the basis of all science and knowledge.
