32. This consideration will serve also to satisfy some modern philosophers who go so far as to say that God is the only agent. It is true that God is the only one whose action is pure and without admixture of what is termed 'to suffer': but that does not preclude the creature's participation in actions, since the action of the creature is a modification of the substance, flowing naturally from it and containing a variation not only in the perfections that God has communicated to the creature, but also in the limitations that the creature, being what it is, brings with it. Thus we see that there is an actual distinction between the substance and its modification or accidents, contrary to the opinion of some moderns and in particular of the late Duke of Buckingham, who spoke of that in a little Discourse on Religion recently reprinted. Evil is therefore like darkness, and not only ignorance but also error and malice consist formally in a certain kind of privation. Here is an example of error which we have already employed. I see a tower which from a distance appears round although it is square. The thought that the tower is what it appears to be flows naturally from that which I see; and when I dwell on this thought it is an affirmation, it is a false judgement; but if I pursue the examination, if some reflexion causes me to perceive that appearances deceive me, lo and behold, I abandon my error. To abide in a certain place, or not to go further, not to espy some landmark, these are privations.
33. It is the same in respect of malice or ill will. The will tends towards good in general, it must strive after the perfection that befits us, and the supreme perfection is in God. All pleasures have within themselves some feeling of perfection. But when one is limited to the pleasures of the senses, or to other pleasures to the detriment of greater good, as of health, of virtue, of union with God, of felicity, it is in this privation of a further aspiration that the defect consists. In general perfection is positive, it is an absolute reality; defect is privative, it comes from limitation and tends towards new privations. This saying is therefore as true as it is ancient: bonum ex causa integra, malum ex quolibet defectu; as also that
which states: malum causam habet non efficientem, sed deficientem. And I hope that the meaning of these axioms will be better apprehended after what I have just said.
34. The physical co-operation of God and of creatures with the will contributes also to the difficulties existing in regard to freedom. I am of opinion that our will is exempt not only from constraint but also from necessity. Aristotle has already observed that there are two things in freedom, to wit, spontaneity and choice, and therein lies our mastery over our actions. When we act freely we are not being forced, as would happen if we were pushed on to a precipice and thrown from top to bottom; and we are not prevented from having the mind free when we deliberate, as would happen if we were given a draught to deprive us of discernment. There is contingency in a thousand actions of Nature; but when there is no judgement in him who acts there is no freedom. And if we had judgement not accompanied by any inclination to act, our soul would be an understanding without will.
35. It is not to be imagined, however, that our freedom consists in an indetermination or an indifference of equipoise, as if one must needs be inclined equally to the side of yes and of no and in the direction of different courses, when there are several of them to take. This equipoise in all directions is impossible: for if we were equally inclined towards the courses A, B and C, we could not be equally inclined towards A and towards not A. This equipoise is also absolutely contrary to experience, and in scrutinizing oneself one will find that there has always been some cause or reason inclining us towards the course taken, although very often we be not aware of that which prompts us: just in the same way one is hardly aware why, on issuing from a door, one has placed the right foot before the left or the left before the right.
36. But let us pass to the difficulties. Philosophers agree to-day that the truth of contingent futurities is determinate, that is to say that contingent futurities are future, or that they will be, that they will happen: for it is as sure that the future will be, as it is sure that the past has been. It was true already a hundred years ago that I should write to-day, as it will be true after a hundred years that I have written. Thus the contingent is not, because it is future, any the less contingent; and determination, which would be called certainty if it were known, is not incompatible with contingency. Often the certain and the determinate are taken as one thing,
because a determinate truth is capable of being known: thus it may be said that determination is an objective certainty.
37. This determination comes from the very nature of truth, and cannot injure freedom: but there are other determinations taken from elsewhere, and in the first place from the foreknowledge of God, which many have held to be contrary to freedom. They say that what is foreseen cannot fail to exist, and they say so truly; but it follows not that what is foreseen is necessary, for necessary truth is that whereof the contrary is impossible or implies contradiction. Now this truth which states that I shall write tomorrow is not of that nature, it is not necessary. Yet supposing that God foresees it, it is necessary that it come to pass; that is, the consequence is necessary, namely, that it exist, since it has been foreseen; for God is infallible. This is what is termed a hypothetical necessity. But our concern is not this necessity: it is an absolute necessity that is required, to be able to say that an action is necessary, that it is not contingent, that it is not the effect of a free choice. Besides it is very easily seen that foreknowledge in itself adds nothing to the determination of the truth of contingent futurities, save that this determination is known: and this does not augment the determination or the 'futurition' (as it is termed) of these events, that whereon we agreed at the outset.
38. This answer is doubtless very correct. It is agreed that foreknowledge in itself does not make truth more determinate; truth is foreseen because it is determinate, because it is true; but it is not true because it is foreseen: and therein the knowledge of the future has nothing that is not also in the knowledge of the past or of the present. But here is what an opponent will be able to say: I grant you that foreknowledge in itself does not make truth more determinate, but it is the cause of the foreknowledge that makes it so. For it needs must be that the foreknowledge of God have its foundation in the nature of things, and this foundation, making the truth predeterminate, will prevent it from being contingent and free.
39. It is this difficulty that has caused two parties to spring up, one of the predeterminators, the other of the supporters of mediate knowledge. The Dominicans and the Augustinians are for predetermination, the Franciscans and the modern Jesuits on the other hand are for mediate knowledge. These two parties appeared towards the middle of the sixteenth century and a little later.
