XII. (40) “And he brought her to Adam. And Adam said, This is now bone of my bone, and flesh of my flesh.” God leads the external sense, existing according to energy, to the mind; knowing that its motion and apprehension must turn back to the mind. But the mind, perceiving the power which it previously had (and which, while it was existing according to habit was in a state of tranquillity), now have to become a complete operation and energy, and to be in a state of motion, marvels at it, and utters an exclamation, saying that it is not unconnected with it, but very closely akin to it. (41) For Adam says, “This now is bone of my bone;” that is to say, This is power of my power; for bone is here to be understood as a symbol of strength and power. And it is, he adds, suffering of my sufferings; that is, it is flesh of my flesh. For every thing which the external sense suffers, it endures not without the support of the mind; for the mind is its fountain, and the foundation on which it is supported. (42) It is also worth while to consider why Adam added the word “now,” for he says, “This now is bone of my bone.” The explanation is, external sensation exists now, having its existence solely with reference to the present moment. For the mind touches three separate points of time; for it perceives present circumstances, and it remembers past events, and it anticipates the future. (43) But the external sensations have neither any anticipation of future events, nor are they subject to any feeling resembling expectation or hope, nor have they any recollection of past circumstances; but are by nature capable only of being affected by that which moves them at the moment, and is actually present. As, for example, the eye is made white by a white appearance presented to it at the moment, but it is not affected in any manner by that which is not present to it. But the mind is agitated also by that which is not actually present, but which may be past; in which cast it is affected by its recollection of it; or it may be future, in which case it is, indeed, the influence of hope and expectation.
