The effects of destiny, which are a sign of the existence of truth, and there is no evidence more evident to a thing than itself. So truth was not known by anything other than itself, but rather it was known by itself and the relation of existence to these entities. We have said that this is the effect of destiny, so we know destiny by its effect and we know truth by its existence. This is because destiny is a special, unknown relation, and truth Existence, so it is valid to relate knowledge to truth, and it is not valid to attach knowledge to destiny, for our knowledge of the appearance of appearance in the eye is the same as our knowledge of truth, and destiny is arranged between the essence and truth in terms of its appearance, it is not known at all, and its ruling in appearances is the ruling of time in the world of bodies, so this is why most investigators call it intelligible times.
