 evil, be (the contrary), for that is also true, and these may exist at the same time, wherefore (the opinion) of what is not good, that it is good, remains as a contrary to the opinion of what is not good, that it is not good, and this will be false, so that the opinion of good that it is not good, will be the contrary to that of what is good, that it is good. That there will be no difference though we should propose universal affirmation is evident, for universal negation will be the contrary; as for instance, to the opinion which supposes every thing good to be good, that nothing of good things is good (will be the contrary opinion), for the opinion of good that it is good, if good be universal, is the same with that which opines that whatever is good is good, and this differs in no respect from the opinion that every thing which is good is good, and the like takes place as to that which is not good. So that if this be the case in opinion, and affirmations and negations in the voice are symbols of (conceptions) in the soul, it is clear that the universal negation which is about the same thing, is contrary to affirmation. For instance, to "every thing good is good," or that "every man is good," (the negation is contrary,) that "nothing or no man is good;" but this, that "not every thing, or not every man," (is good, is opposed) contradictorily. It is however evident, that true opinion can neither possibly be contrary to true opinion, nor true negation (to true negation), for those are contraries which subsist about opposites; but about the same things the same may be verified, but contraries cannot possibly be inherent in the same thing, at one and the same time.
