As a human, you have four basic processes, all indispensable to your survival and happiness: 1. You perceive or sense -- see, taste, smell, feel, hear. 2. You feel or emote -- love, hate, fear, feel guilty or depressed. 3. You move or act -- walk, eat, swim, climb, and so forth. 4. You reason or think -- remember, imagine, hypothesize, conclude, solve problems. Ordinarily, you experience none of these four basic processes in isolation.
