27. It is indeed beyond question that we must refrain from preventing the sin of others when we cannot prevent their sin without sinning ourselves. But someone will perhaps bring up the
objection that it is God himself who acts and who effects all that is real in the sin of the creature. This objection leads us to consider the physical co-operation of God with the creature, after we have examined the moral co-operation, which was the more perplexing. Some have believed, with the celebrated Durand de Saint-Pourçain and Cardinal Aureolus, the famous Schoolman, that the co-operation of God with the creature (I mean the physical cooperation) is only general and mediate, and that God creates substances and gives them the force they need; and that thereafter he leaves them to themselves, and does naught but conserve them, without aiding them in their actions. This opinion has been refuted by the greater number of Scholastic theologians, and it appears that in the past it met with disapproval in the writings of Pelagius. Nevertheless a Capuchin named Louis Pereir of Dole, about the year 1630, wrote a book expressly to revive it, at least in relation to free actions. Some moderns incline thereto, and M. Bernier supports it in a little book on freedom and freewill. But one cannot say in relation to God what 'to conserve' is, without reverting to the general opinion. Also it must be taken into account that the action of God in conserving should have some reference to that which is conserved, according to what it is and to the state wherein it is; thus his action cannot be general or indeterminate. These generalities are abstractions not to be found in the truth of individual things, and the conservation of a man standing is different from the conservation of a man seated. This would not be so if conservation consisted only in the act of preventing and warding off some foreign cause which could destroy that which one wishes to conserve; as often happens when men conserve something. But apart from the fact that we are obliged ourselves sometimes to maintain that which we conserve, we must bear in mind that conservation by God consists in the perpetual immediate influence which the dependence of creatures demands. This dependence attaches not only to the substance but also to the action, and one can perhaps not explain it better than by saying, with theologians and philosophers in general, that it is a continued creation.
28. The objection will be made that God therefore now creates man a sinner, he that in the beginning created him innocent. But here it must be said, with regard to the moral aspect, that God being supremely wise cannot fail to observe certain laws, and to
act according to the rules, as well physical as moral, that wisdom has made him choose. And the same reason that has made him create man innocent, but liable to fall, makes him re-create man when he falls; for God's knowledge causes the future to be for him as the present, and prevents him from rescinding the resolutions made.
29. As for physical co-operation, here one must consider the truth which has made already so much stir in the Schools since St. Augustine declared it, that evil is a privation of being, whereas the action of God tends to the positive. This answer is accounted a quibble, and even something chimerical in the minds of many people. But here is an instance somewhat similar, which will serve to disabuse them.
30. The celebrated Kepler and M. Descartes (in his letters) after him have spoken of the 'natural inertia of bodies'; and it is something which may be regarded as a perfect image and even as a sample of the original limitation of creatures, to show that privation constitutes the formal character of the imperfections and disadvantages that are in substance as well as in its actions. Let us suppose that the current of one and the same river carried along with it various boats, which differ among themselves only in the cargo, some being laden with wood, others with stone, and some more, the others less. That being so, it will come about that the boats most heavily laden will go more slowly than the others, provided it be assumed that the wind or the oar, or some other similar means, assist them not at all. It is not, properly speaking, weight which is the cause of this retardation, since the boats are going down and not upwards; but it is the same cause which also increases the weight in bodies that have greater density, which are, that is to say, less porous and more charged with matter that is proper to them: for the matter which passes through the pores, not receiving the same movement, must not be taken into account. It is therefore matter itself which originally is inclined to slowness or privation of speed; not indeed of itself to lessen this speed, having once received it, since that would be action, but to moderate by its receptivity the effect of the impression when it is to receive it. Consequently, since more matter is moved by the same force of the current when the boat is more laden, it is necessary that it go more slowly; and experiments on the impact of bodies, as well as reason, show that twice as much force must be
employed to give equal speed to a body of the same matter but of twice the size. But that indeed would not be necessary if the matter were absolutely indifferent to repose and to movement, and if it had not this natural inertia whereof we have just spoken to give it a kind of repugnance to being moved. Let us now compare the force which the current exercises on boats, and communicates to them, with the action of God, who produces and conserves whatever is positive in creatures, and gives them perfection, being and force: let us compare, I say, the inertia of matter with the natural imperfection of creatures, and the slowness of the laden boat with the defects to be found in the qualities and the action of the creature; and we shall find that there is nothing so just as this comparison. The current is the cause of the boat's movement, but not of its retardation; God is the cause of perfection in the nature and the actions of the creature, but the limitation of the receptivity of the creature is the cause of the defects there are in its action. Thus the Platonists, St. Augustine and the Schoolmen were right to say that God is the cause of the material element of evil which lies in the positive, and not of the formal element, which lies in privation. Even so one may say that the current is the cause of the material element of the retardation, but not of the formal: that is, it is the cause of the boat's speed without being the cause of the limits to this speed. And God is no more the cause of sin than the river's current is the cause of the retardation of the boat. Force also in relation to matter is as the spirit in relation to the flesh; the spirit is willing and the flesh is weak, and spirits act...
quantum non noxia corpora tardant.
31. There is, then, a wholly similar relation between such and such an action of God, and such and such a passion or reception of the creature, which in the ordinary course of things is perfected only in proportion to its 'receptivity', such is the term used. And when it is said that the creature depends upon God in so far as it exists and in so far as it acts, and even that conservation is a continual creation, this is true in that God gives ever to the creature and produces continually all that in it is positive, good and perfect, every perfect gift coming from the Father of lights. The imperfections, on the other hand, and the defects in operations spring from the original limitation that the creature could not but
receive with the first beginning of its being, through the ideal reasons which restrict it. For God could not give the creature all without making of it a God; therefore there must needs be different degrees in the perfection of things, and limitations also of every kind.
