2. This truth, though it always exists, men do not understand, as well before they hear it as when they hear it for the first time. For although all things happen in accordance with this truth, men seem unskilled indeed when they make trial of words and matters such as I am setting forth, in my effort to discriminate each thing according to its nature, and to tell what its state is. But other men fail to notice what they do when awake, in the same manner that they forget what they do when asleep.

Hippolytos quotes this passage with reference to a universal all-pervading reason.
