The sixth position:

Whatever exists together and in an ordered arrangement must be finite, as in the case of causes and bodies: causes have a natural order, while bodies have a positional order, and all exist at a single instant.

As for things that have no order—such as souls—or that have an order but occur successively—such as motions—there is nothing to preclude an infinite number of them. This is Ibn Sīnā’s position, which they attribute to Aristotle and his followers. Ibn Rushd, however, stated that no philosopher other than Ibn Sīnā held this position.

As for the existence of infinitely many causes and effects, no rational person has considered this possible.

With this understood, we may discuss the argument based on the unequal numbers of infinite revolutions. The sun completes one circuit of the celestial sphere each year, while the moon completes twelve; this is observable. Jupiter completes one circuit every twelve years, and Saturn one every thirty years. Thus, the moon’s revolutions are 360 times as numerous as Saturn’s, and the sun’s are thirty times as numerous as Saturn’s. The revolutions of one are therefore many times those of the other, yet both are infinite according to those who hold this view. Whatever is less than the infinite is finite, and whatever exceeds the finite is finite. It has already been established that the counterargument based on number is invalid.
