LOCKE, as well as all those who have adopted his system, which is so demonstrable,--or to the axiom of ARISTOTLE, which is so clear, ought to have concluded from it that all those wonderful things with which metaphysicians have amused themselves, are mere chimeras; mere wanderings of the imagination; that an immaterial spirit or substance, without extent, without parts, is, in fact, nothing more than an absence of ideas; in short, they ought to have felt that the ineffable intelligence which they have supposed to preside at the helm of the world, is after all nothing more than a being of their own imagination, on which man has never been in accord, whom he has pictured under all the variety of forms, to which he has at different periods, in different climes, ascribed every kind of attribute, good or bad; but of which it is impossible his senses can ever prove either the existence or the qualities.
For the same reason, moral philosophers ought to have concluded, that what is called moral sentiment, _moral instinct_, that is, innate ideas of virtue, anterior to all experience of the good or bad effects resulting from its practice, are mere chimerical notions, which, like a great many others, have for their guarantee and base only metaphysical speculation. Before man can judge, he must feel; before he can distinguish good from evil, he must compare. _Morals_, is a science of facts: to found them, therefore, on an hypothesis inaccessible to his senses, of which he has no means of proving the reality, is to render them uncertain; it is to cast the log of discord into his lap, to cause him unceasingly to dispute upon that which he can never understand. To assert that the ideas of morals are _innate_, or the effect of _instinct_, is to pretend that man knows how to read before he has learned the letters of the alphabet; that he is acquainted with the laws of society before they are either made or promulgated.
To undeceive him, with respect to innate ideas or modifications, imprinted on his soul, at the moment of his birth, it is simply requisite to recur to their source; he will then see that those with which he is familiar, which have, as it were, identified themselves with his existence, have all come to him through the medium of some of his senses; that they are sometimes engraven on his brain with great difficulty,--that they have never been permanent,--that they have perpetually varied in him: he will see that these pretended inherent ideas of his soul, are the effect of education, of example, above all, of habit, which by reiterated motion has taught his brain to associate his ideas either in a confused or a perspicuous manner; to familiarize itself with systems either rational or absurd. In short, he takes those for innate ideas of which he has forgotten the origin; he no longer recals to himself, either the precise epoch, or the successive circumstances when these ideas were first consigned to his brain: arrived at a certain age he believes he has always had the same notions; his memory, crowded with experience, loaded with a multitude of facts, is no longer able to distinguish the particular circumstances which have contributed to give his brain its present modifications; its instantaneous mode of thinking; its actual opinions. For example, not one of his race, perhaps, recollects the first time the word God struck his ears--the first ideas that it formed in him--the first thoughts that it produced in him; nevertheless, it is certain that from thence he has searched for some being with whom to connect the idea which he has either formed to himself, or which has been suggested to him: accustomed to hear God continually spoken of, he has, when in other respects, the most enlightened, regarded this idea as if it were infused into him by Nature; whilst it is visibly to be attributed to those delineations of it, which his parents or his instructors have made to him; which he has, in consequence, modified according to his own particular organization, and the circumstances in which he has been placed; it is thus, that each individual forms to himself a God, of which he is himself the model, or which he modifies after his own fashion.
