When we think of sensory perception, we assume it is simply a process by which we acquire knowledge of an objective external world. Evolution after all has primed us that way, right?
This means that this world consists of physical objects and events that exist independently of us and our acts of perceiving. Problems arise however when we reflect on the nature of this process and on how perceptual knowledge is thought to be acquired. How do we account for cases of optical illusion, or when half of the population deem a dress white and gold and the other half blue and black?
Offering philosophical arguments to make sense of perceptual experiences goes back to the ancients and it was refuelled during the scientific revolution when intellectual titans such as Galileo, Locke and Kant attempted to make sense of the relation between perceptual experience and the physical world.
Today research in psychophysics and the neurosciences brings further insights. Can we detract ourselves from our experiences of reality or is all perception theory-laden and conceptual in nature? These are the questions we investigate on this course.
