Watch and my passion, Every source of movement in the world, whether a person, a thing, or a thought, is a “powered engine”. Thus, the plow moves the earth, the hand moves the plow, the brain moves the hand, the desire for food moves the brain, the instinct of life moves the desire of food, and so on. In other words, the cause of all movement is the result of any other movement, the master of every slave is the slave of some other master. THE The tyrant himself is a slave to his ambition. God, however, cannot be the result of any action. He cannot be a slave to any master. He is the source of all action, the master of all Amos, the instigator of all thought, the "unmoved engine of the world." Aristotle
