De Principiis

⁵ Having refuted, then, as well as we could, every notion which might suggest that we were to think of God as in any degree corporeal, we go on to say that, according to strict truth, God is incomprehensible, and incapable of being measured. For whatever be the knowledge which we are able to obtain of God, either by perception or reflection, we must of necessity believe that He is by many degrees far better than what we perceive Him to be. For, as if we were to see any one unable to bear a spark of light, or the flame of a very small lamp, and were desirous to acquaint such a one, whose vision could not admit a greater degree of light than what we have stated, with the brightness and splendour of the sun, would it not be necessary to tell him that the splendour of the sun was unspeakably and incalculably better and more glorious than all this light which he saw? So our understanding, when shut in by the fetters of flesh and blood, and rendered, on account of its participation in such material substances, duller and more obtuse, although, in comparison with our bodily nature, it is esteemed to be far superior, yet, in its efforts to examine and behold incorporeal things, scarcely holds the place of a spark or lamp. But among all intelligent, that is, incorporeal beings, what is so superior to all others— so unspeakably and incalculably superior— as God, whose nature cannot be grasped or seen by the power of any human understanding, even the purest and brightest?

6. But it will not appear absurd if we employ another similitude to make the matter clearer. Our eyes frequently cannot look upon the nature of the light itself— that is, upon the substance of the sun; but when we behold his splendour or his rays pouring in, perhaps, through windows or some small openings to admit the light, we can reflect how great is the supply and source of the light of the body. So, in like manner. the works of Divine Providence and the plan of this whole world are a sort of rays, as it were, of the nature of God, in comparison with His real substance and being. As, therefore, our understanding is unable of itself to behold God Himself as He is, it knows the Father of the world from the beauty of His works and the comeliness of His creatures. God, therefore, is not to be thought of as being either a body or as existing in a body, but as an uncompounded intellectual nature, admitting within Himself no addition of any kind; so that He cannot be believed to have within him a greater and a less, but is such that He is in all parts Μονάς, and, so to speak, ῾Ενάς, and is the mind and source from which all intellectual nature or mind takes its beginning. But mind, for its movements or operations, needs no physical space, nor sensible magnitude, nor bodily shape, nor colour, nor any other of those adjuncts which are the properties of body or matter. Wherefore that simple and wholly intellectual nature can admit of no delay or hesitation in its movements or operations, lest the simplicity of the divine nature should appear to be circumscribed or in some degree hampered by such adjuncts, and lest that which is the beginning of all things should be found composite and differing, and that which ought to be free from all bodily intermixture, in virtue of being the one sole species of Deity, so to speak, should prove, instead of being one, to consist of many things. That mind, moreover, does not require space in order to carry on its movements agreeably to its nature, is certain from observation of our own mind. For if the mind abide within its own limits, and sustain no injury from any cause, it will never, from diversity of situation, be retarded in the discharge of its functions; nor, on the other hand, does it gain any addition or increase of mobility from the nature of particular places. And here, if any one were to object, for example, that among those who are at sea, and tossed by its waves the mind is considerably less vigorous than it is wont to be on land, we are to believe that it is in this state, not from diversity of situation, but from the commotion or disturbance of the body to which the mind is joined or attached. For it seems to be contrary to nature, as it were, for a human body to live at sea; and for that reason it appears, by a sort of inequality of its own, to enter upon its mental operations in a slovenly and irregular manner, and to perform the acts of the intellect with a duller sense, in as great degree as those who on land are prostrated with fever; with respect to whom it is certain, that if the mind do not discharge its functions as well as before, in consequence of the attack of disease, the blame is to be laid not upon the place, but upon the bodily malady, by which the body, being disturbed and disordered, renders to the mind its customary services under by no means the well-known and natural conditions: for we human beings are animals composed of a union of body and soul, and in this way (only) was it possible for us to live upon the earth. But God, who is the beginning of all things, is not to be regarded as a composite being, lest perchance there should be found to exist elements prior to the beginning itself, out of which everything is composed, whatever that be which is called composite. Neither does the mind require bodily magnitude in order to perform any act or movement; as when the eye by gazing upon bodies of larger size is dilated, but is compressed and contracted in order to see smaller objects. The mind, indeed, requires magnitude of an intellectual kind, because it grows, not after the fashion of a body, but after that of intelligence. For the mind is not enlarged, together with the body, by means of corporal additions, up to the twentieth or thirtieth year of life; but the intellect is sharpened by exercises of learning, and the powers implanted within it for intelligent purposes are called forth; and it is rendered capable of greater intellectual efforts, not being increased by bodily additions, but carefully polished by learned exercises. But these it cannot receive immediately from boyhood, or from birth, because the framework of limbs which the mind employs as organs for exercising itself is weak and feeble; and it is unable to bear the weight of its own operations, or to exhibit a capacity for receiving training.
