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 [141] 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...
