If Light and Darkness had originally Freewill, why do not all things possess it? Does man alone come from a Mixing?

If the Darkness has Freewill -- for behold as they say, by its Will it made an Assault, and, again, if the Light has an independent nature -- if from two natures which have Freewill and Independence and Thought all creatures have come, [lxxxiv] how (?) is it that they all have not Life, and all have not Thought, as also they all have not independent Freewill? And here it is found that man alone is from these two Natures which have these (qualities), because he also has such (qualities) as these. Whence therefore came the rest of creatures and of beasts and plants which do not possess these (qualities), and are not from the two Natures from which man comes? Or let them be convinced that there is one Will which created everything from nothing, as was useful for Freewill and for [P. 111.] our boldness (?) according to the reasoning which we wrote above.
