On the Holy Trinity

^3. Wherefore in all cases the love of a studious mind, that is, of one that wishes to know what it does not know, is not the love of that thing which it does not know, but of that which it knows; on account of which it wishes to know what it does not know. Or if it is so inquisitive as to be carried away, not for any other cause known to it, but by the mere love of knowing things unknown; then such an inquisitive person is, doubtless distinguishable from an ordinary student, yet does not, any more than he, love things he does not know; nay, on the contrary, he is more fitly said to hate things he knows not, of which he wishes that there should be none, in wishing to know everything. But lest any one should lay before us a more difficult question, by declaring that it is just as impossible for any one to hate what he does not know, as to love what he does not know, we will not withstand what is true; but it must be understood that it is not the same thing to say he loves to know things unknown, as to say he loves things unknown. For it is possible that a man may love to know things unknown; but it is not possible that he should love things unknown. For the word to know is not placed there without meaning; since he who loves to know things unknown, does not love the unknown things themselves, but the knowing of them. And unless he knew what knowing means, no one could say confidently, either that he knew or that he did not know. For not only he who says I know, and says so truly, must needs know what knowing is; but he also who says, I do not know, and says so confidently and truly, and knows that he says so truly, certainly knows what knowing is; for he both distinguishes him who does not know from him who knows, when he looks into himself and says truly I do not know; and whereas he knows that he says this truly, whence should he know it, if he did not know what knowing is?
