There are many theories about the human consciousness, leading some to conclude that the mind is one's soul, spirit, or brain. A psychologist might say that the mind is the portion of the brain in which it performs as the conscious and subconscious. Consciousness manifests as feelings, perceptions, thoughts, will, reasoning, memory, and imagination. The mind includes or relies on the parts of the brain in which we process the input of our senses. Here it is that we pay attention, apply knowledge and creativity, form opinions, make decisions, and direct behaviors. In it dwell and are processed concepts, meanings, ambiguities, fantasies, inspirations, mysteries, and motivations.Quote: "I certainly consider a great appreciation of painting to be the best indication of a most perfect mind." Leon Battista Alberti (1404-1472), Italian architect. See appreciation, painting, and Renaissance. "The mind has exactly the same power as the hands; not merely to grasp the world, but to change it." Colin Wilson (1922-), English author. "The mind is like a parachute. It works best when it is open." Anonymous. "[Neo:] 'If you're killed in the Matrix, do you die here?' [Morpheus:] 'The body cannot live without the mind.'"
