3. One of these opinions, revived, however, and introduced by
degenerate scholasticism, and in the Age of Chimeras, is vague indifference of choice, or real chance, assumed in our souls; as if nothing gave us any inclination unless we perceived it distinctly, and as if an effect could be without causes, when these causes are imperceptible. It is much as some have denied the existence of insensible corpuscles because they do not see them. Modern philosophers have improved upon the opinions of the Schoolmen by showing that, according to the laws of corporeal nature, a body can only be set in motion by the movement of another body propelling it. Even so we must believe that our souls (by virtue of the laws of spiritual nature) can only be moved by some reason of good or evil: and this even when no distinct knowledge can be extracted from our mental state, on account of a concourse of innumerable little perceptions which make us now joyful and now sad, or again of some other humour, and cause us to like one thing more than another without its being possible to say why. Plato, Aristotle and even Thomas Aquinas, Durand and other Schoolmen of the sounder sort reason on that question like the generality of men, and as unprejudiced people always have reasoned. They assume that freedom lies in the use of reason and the inclinations, which cause the choice or rejection of objects. But finally some rather too subtle philosophers have extracted from their alembic an inexplicable notion of choice independent of anything whatsoever, which is said to do wonders in solving all difficulties. But the notion is caught up at the outset in one of the greatest difficulties, by offending against the grand principle of reasoning which makes us always assume that nothing is done without some sufficient cause or reason. As the Schoolmen often forgot to apply this great principle, admitting certain prime occult qualities, one need not wonder if this fiction of vague indifference met with applause amongst them, and if even most worthy men have been imbued therewith. Our author, who is otherwise rid of many of the errors of the ordinary Schoolmen, is still deluded by this fiction: but he is without doubt one of the most skilful of those who have supported it.
Si Pergama dextra
Defendi possent, etiam hac defensa fuissent.
He gives it the best possible turn, and only shows it on its good side. He knows how to strip spontaneity and reason of their
advantages, transferring all these to vague indifference: only through this indifference is one active, resisting the passions, taking pleasure in one's choice, or being happy; it appears indeed that one would be miserable if some happy necessity should oblige us to choose aright. Our author had said admirable things on the origin and reasons of natural evils: he only had to apply the same principles to moral evil; indeed, he believes himself that moral evil becomes an evil through the physical evils that it causes or tends to cause. But somehow or other he thinks that it would be a degradation of God and men if they were to be made subject to reason; that thus they would all be rendered passive to it and would no longer be satisfied with themselves; in short that men would have nothing wherewith to oppose the misfortunes that come to them from without, if they had not within them this admirable privilege of rendering things good or tolerable by choosing them, and of changing all into gold by the touch of this wondrous faculty.
4. We will examine it in closer detail presently; but it will be well to profit beforehand by the excellent ideas of our author on the nature of things and on natural evils, particularly since there are some points in which we shall be able to go a little further: by this means also we shall gain a better understanding of the whole arrangement of his system. The first chapter contains the principles. The writer calls substance a being the idea of which does not involve the existence of another. I do not know if there are any such among created beings, by reason of the connexion existing between all things; and the example of a wax torch is not the example of a substance, any more than that of a swarm of bees would be. But one may take the terms in an extended sense. He observes aptly that after all the changes of matter and after all the qualities of which it may be divested, there remain extension, mobility, divisibility and resistance. He explains also the nature of notions, and leaves it to be understood that universals indicate only the resemblances which exist between individuals; that we understand by ideas only that which is known through an immediate sensation, and that the rest is known to us only through relations with these ideas. But when he admits that we have no idea of God, of spirit, of substance, he does not appear to have observed sufficiently that we have immediate apperception of substance and of spirit in our apperception of ourselves, and that
the idea of God is found in the idea of ourselves through a suppression of the limits of our perfections, as extension taken in an absolute sense is comprised in the idea of a globe. He is right also in asserting that our simple ideas at least are innate, and in rejecting the Tabula rasa of Aristotle and of Mr. Locke. But I cannot agree with him that our ideas have scarce any more relation to things than words uttered into the air or writings traced upon paper have to our ideas, and that the bearing of our sensations is arbitrary and ex instituto, like the signification of words. I have already indicated elsewhere why I am not in agreement with our Cartesians on that point.
5. For the purpose of advancing to the first Cause, the author seeks a criterion, a distinguishing mark of truth; and he finds it in the force whereby our inward assertions, when they are evident, compel the understanding to give them its consent. It is by such a process, he says, that we credit the senses. He points out that the distinguishing mark in the Cartesian scheme, to wit, a clear and distinct perception, has need of a new mark to indicate what is clear and distinct, and that the congruity or non-congruity of ideas (or rather of terms, as one spoke formerly) may still be deceptive, because there are congruities real and apparent. He appears to recognize even that the inward force which constrains us to give our assent is still a matter for caution, and may come from deep-rooted prejudices. That is why he confesses that he who should furnish another criterion would have found something very advantageous to the human race. I have endeavoured to explain this criterion in a little Discourse on Truth and Ideas, published in 1684; and although I do not boast of having given therein a new discovery I hope that I have expounded things which were only confusedly recognized. I distinguish between truths of fact and truths of reason. Truths of fact can only be verified by confronting them with truths of reason, and by tracing them back to immediate perceptions within us, such as St. Augustine and M. Descartes very promptly acknowledged to be indubitable; that is to say, we cannot doubt that we think, nor indeed that we think this thing or that. But in order to judge whether our inward notions have any reality in things, and to pass from thoughts to objects, my opinion is that it is necessary to consider whether our perceptions are firmly connected among themselves and with others that we have had, in such fashion as to manifest the rules of mathematics and
other truths of reason. In this case one must regard them as real; and I think that it is the only means of distinguishing them from imaginations, dreams and visions. Thus the truth of things outside us can be recognized only through the connexion of phenomena. The criterion of the truths of reason, or those which spring from conceptions, is found in an exact use of the rules of logic. As for ideas or notions, I call real all those the possibility of which is certain; and the definitions which do not mark this possibility are only nominal. Geometricians well versed in analysis are aware what difference there is in this respect between several properties by which some line or figure might be defined. Our gifted author has not gone so far, perhaps; one may see, however, from the account I have given of him already, and from what follows, that he is by no means lacking in profundity or reflexion.
