‘The orator will present three several pictures to the imagination of his supposed hearer: in the first he will represent a just king, who condemns and gives orders for the execution of a criminal; in the second, will be seen the good king, who opens the doors of his dungeon, and strikes off the chains of the same criminal; in the third picture, the criminal himself will be the principal figure, who, armed with a poniard, on his escape from his cell hastens to assassinate fifty of his fellow-citizens. But who is there that at the sight of these three pictures will not instantly perceive that justice which, by the death of a single individual, saves the lives of fifty persons, is preferable to mercy? Nevertheless, this judgment is really nothing but a sensation. In fact, if from the habit of connecting certain ideas with certain words, the sound of these words may, as experience demonstrates, excite in us almost the same sensations which we should feel from the actual presence of the objects, it is evident that from the contemplation of these three pictures, to judge that in a king justice is preferable to mercy, is to feel and see that in the first picture a single citizen is sacrificed, while in the third fifty are massacred; whence I conclude that every act of the judgment is only a sensation.’—Helvetius on the Mind, p. 12.
On this statement I may be permitted to remark that as the author affirms that sensation is the same thing as judgment, so he seems to conceive that the assertion of any proposition is the same thing as the proof of it. He supposes three several pictures to be presented to a man of understanding, and that from an attentive contemplation and comparison of the different objects and events contained in them, he comes to a judgment or conclusion, viz. That justice is preferable to mercy. ‘Nevertheless,’ he says, ‘this judgment is really nothing but a sensation.’ This is all the proof he brings; and perhaps, considering the language and country in which this celebrated author wrote, it is reasoning good enough. Do I say this with any view to throw contempt on that lively, ingenious, gay, social, and polished people? No; but philosophy is not their forte: they are not in earnest in these remote speculations. In order duly to appreciate their writings, we must consider them not as the dictates of the understanding, but as the effects of constitution. Otherwise we shall do them great injustice. They pursue truth, like all other things, as far as it is agreeable; they reason for their amusement; they engage in abstruse questions to vary the topics of conversation. Whatever does not answer this purpose is banished out of books and society as a morose and cynical philosophy. To obtrude the dark and difficult parts of a question, or to enter into an elaborate investigation of them, is considered as a piece of ill-manners. Those writers, therefore, have been the most popular among the French who have supplied their readers with the greatest number of dazzling conclusions founded on the most slight and superficial evidence, whose reasonings could be applied to every thing, because they explained nothing, and who most effectually kept out of sight every thing true or profound or interesting in a question. Who would ever think of plunging into abstruse, metaphysical inquiries concerning the nature of the understanding, when he may with entire ease to himself and satisfaction to others solve all the phenomena of the mind by repeating in three words, Juger est sentir. As it was the object of the school-philosophy, by a jargon of technical distinctions, to sharpen the eagerness of debate and give birth to endless verbal controversies, so the modern system, transferring philosophy from the cloistered hall to the toilette and the drawing-room, is calculated, by a set of portable phrases, as familiar and as current as the forms of salutation, to silence every difference of opinion, and to produce an euthanasia of all thought. I have made these remarks not to prejudice the question, but to prevent the prejudice arising on the other side, from seeing the writers of a whole nation, not deficient in natural talents or in acquired advantages, agree in delivering the most puerile absurdities as profound and oracular truths.
The train of thought into which the author has fallen in the passage above cited is pretty obvious. Having undertaken to prove that the ideas of justice and mercy are mere sensations, and that the conclusion that justice is preferable to mercy is also a mere sensation, in order to shew the possibility of this he conjures up the ideas of a good and a bad king, of a criminal, a prison, chains, a dagger, and fifty citizens massacred before the eyes of the spectator, which form the subject of three imaginary pictures, and which are in general considered as so many sensible objects. All these sensible objects he supposes to be implied in, and to be the materials out of which we frame the judgment or conclusion, that justice is better than mercy; and therefore he infers that there is nothing else implied in or necessary to that judgment, and that consequently it is nothing but a sensation. Having succeeded in resolving the compound and general ideas of justice and mercy, good and evil, into a number of sensible appearances, his imagination is entirely occupied with the novelty of the objects before him, and he drops altogether the consideration, whether the combination and comparison of these several objects or sensations which is absolutely necessary to their forming the moral ideas or inference spoken of, is not the act of some other faculty. In short, the principle that a judgment is nothing but a sensation, is not only a perfectly gratuitous assertion, but an assertion either without meaning, or a palpable contradiction. For the single objects presented in the foregoing metaphysical pictures, and which are supposed to constitute the judgment, are not one sensation, but many. Now if it be meant that these single objects, as they are perceived separately, or successively, one by one, without the intervention of any reflex act of the mind combining and comparing them together, constitute of themselves the judgment, ‘that justice is preferable to mercy,’ this is to say, in so many words, that the mind forms a comparison between things without comparing them, and judges of their relations without perceiving them. On the other hand, if it be meant to include the acts of the mind in comparing, judging, inferring, &c. in the term sensation, then the proposition that judgment or sensation are the same, will be nothing but an idle and insignificant abuse of words, and will only prove that if to the sensation, or perception of particular objects we add the faculty of comparing and judging, nothing farther will be necessary for it to compare and judge. I shall therefore dismiss this well known maxim as no better than a misnomer, as an attempt to shorten the labour of thought by the interposition of an unmeaning phrase, and to confound all the distinctions of the understanding by an equivoque.
It will not be amiss in this place to transcribe a passage from the Logic of the Abbé Condillac (a work which may be regarded as the quintessence of slender thought, and of the art of substituting words for things) to show how far the doctrine of the origin of all our ideas from sensation may be carried, and what an imbecility it produces in the mind, and deadness to any but external objects. The design of the passage is to prove that morality is a visible thing. This however is a work of supererogation, even on the principle supposed: for it is not necessary to refer morality to any thing visible or audible, or to any other of the senses, but the sense of pleasure and pain; our feelings of this kind being allowed to come from, and make a part of our original sensations. But this system is not an improvement on reason, but a progression in superficiality and absurdity, a vast vacuity, where ‘fluttering its pennons vain, the mind drops down ten thousand fathoms deep.’
‘Moral ideas,’ says my author, ‘seem to elude the senses: they at least elude the senses of those philosophers who deny that our knowledge proceeds from sensation. They would gladly know of what colour virtue is, or of what colour vice is. I answer that virtue consists in the habitual performance of good actions, as vice consists in the habitual performance of bad ones. Now these habits and these actions are visible.
‘What, then, is the morality of actions a thing which falls under the cognizance of the senses! Wherefore should it not? Morality depends solely on the conformity between our actions and the laws; but these actions are visible, and the laws are so equally, since they are certain conventions made by men.
‘But it will be said, if the laws are only things of convention, they must be altogether arbitrary. They may indeed be sometimes arbitrary; there are but too many such laws; but those which determine whether our actions are good or bad, are not so, nor can they be so. They are the work of man, it is true, because they are conventions which we have made; nevertheless, we alone have not made them: nature made them as well as we, she dictated them to us, and it was not in our power to make others. The wants and the faculties of man being given, the laws which are to regulate his conduct must necessarily follow: and though we enacted them, God who has created us with such wants and such faculties, is in truth our sole legislator. In obeying the laws which are conformable to our nature, we render obedience to him who is the author of our nature; and this is that which perfects the morality of actions.’—Page 56.
For a work entitled Logic, there are a pleasant number of contradictions in this passage. To pass over many of them, if the laws here spoken of are such merely in consequence of their being visible, then all visible objects are laws, and all laws are equally moral. But no! there are some arbitrary laws. Now if the goodness of the law depends on their conformity to our wants and faculties, neither of these are visible, any more than God who is said to be our only lawgiver. So that ‘the latter end of this system of law and divinity forgets the beginning.’ That those actions are moral which are conformable to a moral law, and that those laws are moral, which are agreeable to our nature and wants, may be readily admitted: but I cannot myself think that this conformity is an object of the senses, or that the true features of morality can ever be discerned but by the eye of the understanding. The friends of morality, it seems, according to our author, are not to despair, or to suppose that the distinctions of right and wrong are banished entirely out of the material system. They only become more clear and legible than ever; we are still right in asserting virtue to have a real existence, namely, on paper, and in supposing that we have some idea of it, as consisting of the letters of the alphabet. Almost in the same manner, Mr. Horne Tooke very gravely defines the essence of law and just, from the etymology of these words, to consist in their being something laid down, and something ordered (jussum); and when pressed by the difficulty that there are many things laid down and ordered which are neither laws nor just, he makes answer that their obligation depends on a higher species of law and justice, to wit, a law which is no where laid down, and a justice which is no where ordered, except indeed by the nature of things, on which the etymology of these two words does not seem to throw any light.
On all the other points of the modern metaphysical system, such as the nature of abstraction, judgment and reasoning, the materiality of the soul, free-will, the association of ideas, &c. Mr. Locke either halts between two opinions, or else takes the common-place side of the question. The motion of the system, which bears his name and which by this very delay gained all that it wanted to become popular, was retrograde in him, not progressive. The extracts I am about to give from his work will I think establish this point. They will at the same time show him to be a man of strong practical sense, of much serious thought and inquiry, and considerable freedom of opinion, and a real lover of truth, though not so bold and systematic a reasoner, or so great a dealer in paradoxes as some others. Moderation, caution, a wish to examine every side of a question, and an unwillingness to decide till after the most mature and circumspect investigation, and then only according to the clearness of the evidence, seem to have been the characteristics of his mind, none of which denote the daring innovator, or maker of a system. What there is of system in his work is Hobbes’s, as I have already shown: the deviations from its common sense and general observation are his own. There is throughout his reasoning the same contempt for the schoolmen, and the same preference of native, rustic reason to learned authority: the same notion of the necessity for reforming the system of philosophy, and of the possibility of doing this by a more exact use of words: there is the same dissatisfaction with the prevailing system, but he at the same time entertained doubts of his own. What he wanted was confidence and decision. The prolixity and ambiguity of his style seem to have arisen from this source: for he is never weary of examining and re-examining the same objection, and he states his arguments with so many limitations and with such a variety of expression to prevent misapprehension, that it is often difficult to guess at his real meaning. There is it must be confessed a sort of heaviness about him, a want of clearness and connection, which in spite of all his pains, and the real plodding strength of his mind he was never able to overcome. To return to his account of complex ideas: the beginning of his observations on this subject is as follows:
‘We have hitherto considered those ideas, in the reception whereof the mind is only passive, which are those simple ones received from sensation and reflection before mentioned, whereof the mind cannot make one to itself, nor have any idea which does not consist wholly of them. But as the mind is wholly passive in the reception of all its simple ideas, so it exerts several acts of its own, whereby out of its simple ideas, as the materials and foundations of the rest, the other are framed. The acts of the mind wherein it exerts its power over its simple ideas, are chiefly these three.
