Intelligence is finite in both directions: on the upper side, by reason of will, which is above it; on the lower, by reason of matter, which is outside of its essence. Hence, spiritual substances are finite with respect to matter, because they differ through it, and distinction is the cause of finitude; in respect to forms they are infinite on the lower side, because one form flows from another. And we must bear in mind that that part of matter which is above heaven, the more it ascends from it to the principle of creation, becomes the more spiritual in form, whereas that part which descends lower than the heaven toward quiet will be more corporeal in form. Matter, intelligence, and soul comprehend heaven, and heaven comprehends the elements. And just as, if you imagine your soul standing at the extreme height of heaven, and looking back upon the earth, the earth will seem but a point, in comparison with the heaven, so are corporeal and spiritual substance in comparison with the will. And first matter is stable in the knowledge of God, as the earth in the midst of heaven. And the form diffused through it is as the light diffused through the air.... We must bear in mind that the unity induced by the will (we might say, the will itself) binds matter to form. Hence that union is stable, firm, and perpetual from the beginning of its creation; and thus unity sustains all things. Matter is movable, in order that it may receive form, in conformity with its appetite for receiving goodness and delight through the reception of form. In like manner, everything that is, desires to move, in order that it may attain something of the goodness of the primal being; and the nearer anything is to the primal being, the more easily it reaches this, and the further off it is, the more slowly and with the longer motion and time it does so. And the motion of matter and other substances is nothing but appetite and love for the mover toward which it moves, as, for example, matter moves toward form, through desire for the primal being; for matter requires light from that which is in the essence of will, which compels matter to move toward will and to desire it: and herein will and matter are alike. And because matter is receptive of the form that has flowed down into it by the flux of violence and necessity, matter must necessarily move to receive form; and therefore things are constrained by will and obedience in turn. Hence by the light which it has from will, matter moves toward will and desires it; but when it receives form, it lacks nothing necessary for knowing and desiring it, and nothing remains for it to seek for. For example, in the morning the air has an imperfect splendor from the sun; but at noon it has a perfect splendor, and there remains nothing for it to demand of the sun. Hence the desire for the first motion is a likeness between all substances and the first Maker, because it is impressed upon all things to move toward the first; because particular
