The Refutation of All Heresies

And people affirm that Plato says, that some things are without a mean, that others have a mean, that others are a mean. (For example, that) waking and sleep, and such like, are conditions without an intermediate state; but that there are things that had means, for instance virtue and vice; and there are means (between extremes), for instance grey between white and black, or some other colour. And they say, that he affirms that the things pertaining to the soul are absolutely alone good, but that the things pertaining to the body, and those external (to it), are not any longer absolutely good, but reputed blessings.

And that frequently he names these means also, for that it is possible to use them both well and ill. Some virtues, therefore, he says, are extremes in regard of intrinsic worth, but in regard of their essential nature means, for nothing is more estimable than virtue. But whatever excels or falls short of these terminates in vice. For instance, he says that there are four virtues— prudence, temperance, justice, fortitude— and that on each of these is attendant two vices, according to excess and defect: for example, on prudence, recklessness according to defect, and knavery according to excess; and on temperance, licentiousness according to defect, stupidity according to excess; and on justice, foregoing a claim according to defect, unduly pressing it according to excess; and on fortitude, cowardice according to defect, foolhardiness according to excess.

And that these virtues, when inherent in a man, render him perfect, and afford him happiness. And happiness, he says, is assimilation to the Deity, as far as this is possible; and that assimilation to God takes place when any one combines holiness and justice with prudence. For this he supposes the end of supreme wisdom and virtue. And he affirms that the virtues follow one another in turn, and are uniform, and are never antagonistic to each other; whereas that vices are multiform, and sometimes follow one the other, and sometimes are antagonistic to each other.

He asserts that fate exists; not, to be sure, that all things are produced according to fate, but that there is even something in our power, as in the passages where he says, “The fault is his who chooses, God is blameless;”and “the following law of Adrasteia.” And thus some (contend for his upholding) a system of fate, whereas others one of free-will. He asserts, however, that sins are involuntary. For into what is most glorious of the things in our power, which is the soul, no one would (deliberately) admit what is vicious, that is, transgression, but that from ignorance and an erroneous conception of virtue, supposing that they were achieving something honourable, they pass into vice.

And his doctrine on this point is most clear in The Republic, where he says, “But, again, you presume to assert that vice is disgraceful and abhorred of God; how then, I may ask, would one choose such an evil thing? He, you reply, (would do so) who is worsted by pleasures. Therefore this also is involuntary, if to gain a victory be voluntary; so that, in every point of view, the committing an act of turpitude, reason proves to be involuntary.” Some one, however, in opposition to this (Plato), advances the contrary statement, “Why then are men punished if they sin involuntary?”But he replies, that he himself also, as soon as possible, may be emancipated from vice, and undergo punishment.

For that the undergoing punishment is not an evil, but a good thing, if it is likely to prove a purification of evils; and that the rest of mankind, hearing of it, may not transgress, but guard against such an error. (Plato, however, maintains) that the nature of evil is neither created by the Deity, nor possesses subsistence of itself, but that it derives existence from contrariety to what is good, and from attendance upon it, either by excess and defect, as we have previously affirmed concerning the virtues. Plato unquestionably then, as we have already stated, collecting together the three departments of universal philosophy, in this manner formed his speculative system.
