IN THE INTELLIGIBLE STABILITY DOES NOT IMPLY STILLNESS.
But why should we not regard the stability of intelligible things also as a negation of movement? Because stability is not the privation of movement; it does not begin to exist when movement ceases, and it does not hinder it from simultaneous existence with it. In intelligible being, stability does not imply the cessation of movement of that whose nature it is to move.[430] On the contrary, so far as intelligible being is contained in (or, expressed by) stability, it is stable; so far as it moves, it will ever move; it is therefore stable by stability, and movable by movement. The body, however, is no doubt moved by movement, but it rests only in the absence of movement, when it is deprived of the movement that it ought to have. Besides, what would stability be supposed to imply (if it were supposed to exist in sense-objects)? When somebody passes from sickness to health, he enters on convalescence. What kind of stillness shall we oppose to convalescence? Shall we oppose to it that condition from which that man had just issued? That state was sickness, and not stability. Shall we oppose to it the state in which that man has just entered? That state is health, which is not identical with stability. To say that sickness and health are each of them a sort of stability, is to consider sickness and health as species of stability, which is absurd. Further, if it were said that stability is an accident of health, it would result that before stability health would not be health. As to such arguments, let each reason according to his fancy!
