[Footnote 1: Malebranche's refutation of the emanation hypothesis of the Peripatetics is acute and still worthy of attention. If bodies transmitted to the sense-organs forms like themselves, these copies, which would evidently be corporeal, must, by their departure, diminish the mass of the body from which they came away, and also, because of their impenetrability, obstruct and interfere with one another, thus destroying the possibility of clear impressions. A further point against the image theory is furnished by the increase in the size of an object, when approached. And, above all, it can never be made conceivable how motion can be transformed into sensations or ideas.] As the knowledge of truth has been found to consist in seeing things as God sees them, so morality consists in man's loving things as God loves them, or, what amounts to the same thing, in loving them to that degree which is their due in view of their greater or less perfection. If, in the last analysis, all cognition is knowledge of God, so all volition is loving God; there is implanted in every creature a direction toward the Creator. God is not only the primordial, unlimited being, he is also the highest good, the final end of all striving. As the ideas of things are imperfect participations in, or determinations of universal being, the absolute perfection of God, so the particular desires, directed toward individual objects, are limitations of the universal will toward the good. How does it happen that the human will, so variously mistaking its fundamental direction toward God, attaches itself to perishable goods, and prefers worthless objects to those which have value, and earthly to heavenly pleasure? The soul is, on the one hand, united to God, on the other, united to the body. The possibility of error and sin rests on its union with the body, since with the ideas (as representations of the pure understanding) are associated sensuous images, which mingle with and becloud them, and passions with the inclinations (or the will of the soul, in so far as it is pure spirit). This gives, however, merely the possibility of the immoral, sensuous, God-estranged disposition, which becomes actual only through man's free act, when he fails to stand the test. For sin does not consist in having passions, but in consenting to them. The passion is not caused by the corporeal movement of which it is the sequel, but only occasioned by it; and the same is true of the movement of the limbs and the decision of the will. The one true cause of all that happens is God. It is he who produces affections in the soul, and motion in the material world. For the body possesses only the capacity of being moved; and the soul cannot be the cause of the movement, since it would then have to know how it produces the latter. In fact those who lack a medical training have no idea of the muscular and nervous processes involved. Without God we cannot even move the tongue.
