Because planets are much fainter than their stars, fewer than have been imaged directly. These are good because each has the common good as its goal. In the 2nd century BC, Hipparchusaware of the extraordinary accuracy with which Babylonian astronomers could predict the planets' motions, insisted that Greek astronomers achieve similar levels of accuracy.

This is described in a separate article; here we shall focus on the original Greek civilization. Without wisdom, there is only a shadow or imitation of virtue, and such lives are still dominated by passion, desire, and emotions.

Thus, the unmoved mover causes the cosmos to move toward its own perfection.Many of the ancient Greeks' discoveries and inventions are still used today, although some of their ideas have been overturned.
