"To understand Aristotle's conception of 'cause,' it helps to keep in mind that most of his explanations revolve around changes. Aristotle recognized four kinds of change: (1) motion, or change of place; (2) the coming to be or pasing away of a thing (these are sometimes called 'generation and corruption'), such as conception, death, the manufacture of a shore or of a staute; (3) growth or diminution, like inflating a balloon or putting on weight (and their opposites); and (4) alteration in quality, such as getting warm or changing colors. We could sum it up in Aristotelian terminology by saying that changes occur in the categories of place, substance, quantity and quality. [Robinson, p. 15.]
