One of the largest philosophical mystery of the science of sensation and perception begins with the idea of “qualia.” Qualia is defined as the qualities of a conscious experience. When you see a striking painting, you may notice its vibrant colors, its beautiful brush strokes, or even the smell of aging canvas. These are all qualia. In the following video, Dr. V.S. Ramachandra delves into the idea of qualia and how it relates to consciousness.
The mystery arises when you consider the mechanism of sensation and perception. Do we need an ineffable, subjective experience to sense and to perceive a film, a song, or a painting? If not, why do we have qualia? And even more puzzling, where does it come from? As your grade school teacher might have once said, “there are no right answers.” But as is the nature of science, perhaps the proper adage is “there are no right answers yet.”
