Answer to Eunomius' Second Book
Such are the clever discoveries of Eunomius against the truth. For what need is there to go through all his argument with trifling prolixity? For in every instance you may see an attempt to establish the same futility. For instance, by an implication such as that above, what is true and what is just will be found opposed to each other; for there is a difference in meaning between truth and justice. So that by a parity of reasoning Eunomius will say about these also, that truth is not injustice, and that justice is absent from truth; and it will happen that, when in respect of God we think of His being alien to injustice, the Divine Being will be shown to be at once just and untrue, while if we regard His being alien to untruth, we prove Him to be at once true and unjust. So, too, of His being invisible and formless. For according to a wise reasoning similar to that which we have adduced, it will not be permissible to say either that the invisible exists in that which is formless, or to say that that which is formless exists in that which is invisible; but he will comprise form in that which is invisible, and so again, conversely, he will prove that that which is formless is visible, using the same language in respect of these as he devised in respect to that which is imperishable and unbeginning, to the effect that when we regard the incomposite nature of the Divine Life, we confess that it is formless, yet not invisible; and that when we reflect that we cannot see God with our bodily eyes, while thus admitting His invisibility, we cannot admit His being formless. Now if these instances seem ridiculous and foolish, much more will every sensible man condemn the absurdity of the statements, starting from which his argument has logically brought him to such a pitch of absurdity. Yet he carps at the Master's words, as wrong in seeing that which is imperishable in that which is unending, and that which is unending in that which is imperishable. Well, then, let us also have our sport, in a manner something like this cleverness of Eunomius. Let us examine his opinion about these two names aforesaid, and see what it is.
Either, he says, that which is endless is distinct in meaning from that which is imperishable, or else the two must make one. But if he call both one, he will be supporting our argument. But if he say that the meaning of the imperishable is one thing, and that that of being unending is another, then of necessity, in the case of things differing from each other, the force of the one cannot be equivalent to the force of the other. If, then, the idea of the imperishable is one, and that of being endless is another, and each of these is what the other is not, neither will he grant that the imperishable is unending, nor that the unending is imperishable, but the unending will be perishable, and the imperishable will be terminable. But I must beg my readers not to turn a ridiculous method of condemnation against us. We have been compelled to adopt such a sportive vein against the mockeries of our opponent, that we might thereby break through the puerile toil of his sophistries. But if it would not be too wearisome to my readers, it would not be out of place again to set forth what Eunomius says in his own words. “If,” says he, “God is imperishable only by reason of the unending in His Life, and ungenerate only by reason of the unbeginning, then wherein He is not imperishable He is perishable, and wherein He is not ungenerate He is generated.” Then returning to the charge, he repeats, “He will then be, as unbeginning, at once ungenerate and perishable: and, as unending, at once imperishable and generated;” for I pass over the superfluous and unseasonable remarks which he has interspersed here, as in no way contributing to the proving of his point. Now I think it is easy for any one to see, by his own words, that the drift of our argument has no connection whatever with the accusation which he lays against us. “For we call the God of the universe imperishable and ungenerate,” says the Master, “using these words with different applications.” “His transcending,” he continues, “every limit of the ages, and every distance in temporal extension, whether we consider the previous or the subsequent, this absence of limit or circumscription on either hand in the Eternal Life we mark in the one case with the name of imperishability, and in the other case with the name of ungeneracy.” But Eunomius would make out that we say that the being without beginning is His essence, and again that the being without end is His essence, as though we brought forward two contradictory segments of essence; and in this way he establishes an absurdity, and while laying down, and then fighting against, positions of his own, and reducing notions of his own concoction to an absurdity, he lays no hold on our argument in any single point. For that God is imperishable only wherein His Life is unending, is his statement, not ours. In like manner, that the imperishable is not without beginning, is an invention of that same subtle cleverness which would constitute a negative attribute an essence; whereas we do not define any such negative attribute as an essence. Now it is a negative attribute of God, that neither does the Life cease in dissolution, nor did It have a commencement in generation; and this we express by these two words, imperishability and ungeneracy. But Eunomius, mixing up his own folly with our teaching, does not seem to understand that he is publishing his own disgrace by his calumnious accusations. For, in defining ungeneracy as an essence, he will logically arrive at the same pitch of absurdity which he ascribes to our teaching. For as beginning means one thing, and end means another, by virtue of an intervening extension, if any one allow the privation of the first of these to be essence, he must suppose His Life to be only half subsisting in this being without beginning, and not to extend further, by virtue of His nature, to the being without end, if ungeneracy be regarded as itself His nature. But if any one insist that both are essence, then, according to the definition put forward by Eunomius, each of these terms must necessarily, by virtue of its inherent meaning, be counted as essence, being just as much as, and no more than, is indicated by the meaning of the term; and thus the argument of Eunomius will not be without force, inasmuch as that which is without beginning does not involve the notion of being without end, and vice versa, since according to his account each of the things mentioned is an essence, and there is no confusion between the two in their relation to each other, the notion of beginning being different to that of ending, while the words which express privation of these also differ in their significations.
