 benefit enemies, and to injure friends, are contrary to benefiting friends, and similarly to each of the others, there will appear two contraries, to those who consider them after the same manner, nevertheless, whichever contrary is useful to the thesis should be assumed.

Also whether such a thing has been predicated of any, which existing, contraries must necessarily be inherent; thus if any one said that ideas are in us, for it will happen that they will both be moved and be at rest; also be both sensible and intelligible. For ideas, to those who admit their existence, appear to rest, and to be intelligible; but if they are in us, they cannot be immovable, for since we are moved, it is necessary that all things in us should be moved together with us, it is also clear that they are sensible if they are in us, for through the sense of sight we know the form which is in every thing.
