9. But when the human mind knows itself and loves itself, it does not know and love anything unchangeable: and each individual man declares his own particular mind by one manner of speech, when he considers what takes place in himself; but defines the human mind abstractly by special or general knowledge. And so, when he speaks to me of his own individual mind, as to whether he understands this or that, or does not understand it, or whether he wishes or does not wish this or that, I believe; but when he speaks the truth of the mind of man generally or specially, I recognize and approve. Whence it is manifest, that each sees a thing in himself, in such way that another person may believe what he says of it, yet may not see it; but another [sees a thing] in the truth itself, in such way that another person also can gaze upon it; of which the former undergoes changes at successive times, the latter consists in an unchangeable eternity. For we do not gather a generic or specific knowledge of the human mind by means of resemblance by seeing many minds with the eyes of the body: but we gaze upon indestructible truth, from which to define perfectly, as far as we can, not of what sort is the mind of any one particular man, but of what sort it ought to be upon the eternal plan.
