СКАЧАТЬ from experience, that experience limiting it to agents possessed of intelligence and will. It is the notion of power combined with a purpose and an end. Physical phenomena, as such, are without sense; and experience teaches us nothing about physical phenomena as causes. Accordingly, wherever the world is young, the movements and changes of physical nature have been and are spontaneously ascribed by its people to the presence and will of hidden agents, who haunt every part of it, the woods, the mountains and the streams, the air and the stars, for good or for evil;—just as children again, by beating the ground after falling, [pg 067] imply that what has bruised them has intelligence;—nor is there anything illogical in such a belief. It rests on the argument from analogy.

      As time goes on, and society is formed, and the idea of science is mastered, a different aspect of the physical universe presents itself to the mind. Since causation implies a sequence of acts in our own case, and our doing is always posterior, never contemporaneous or prior, to our willing, therefore, when we witness invariable antecedents and consequents, we call the former the cause of the latter, though intelligence is absent, from the analogy of external appearances. At length we go on to confuse causation with order; and, because we happen to have made a successful analysis of some complicated assemblage of phenomena, which experience has brought before us in the visible scene of things, and have reduced them to a tolerable dependence on each other, we call the ultimate points of this analysis, and the hypothetical facts in which the whole mass of phenomena is gathered up, by the name of causes, whereas they are really only the formula under which those phenomena are conveniently represented. Thus the constitutional formula, “The king can do no wrong,” is not a fact, or a cause of the Constitution, but a happy mode of bringing out its genius, of determining the correlations of its elements, and of grouping or regulating political rules and proceedings in a particular direction and in a particular form. And in like manner, that all the particles of matter throughout the universe are attracted to each other with a force varying inversely with the square of their respective distances, is a profound [pg 068] idea, harmonizing the physical works of the Creator; but even could it be proved to be a universal fact, and also to be the actual cause of the movements of all bodies in the universe, still it would not be an experience, any more than is the mythological doctrine of the presence of innumerable spirits in physical phenomena.

      Of these two senses of the word “cause,” viz. that which brings a thing to be, and that on which a thing under given circumstances follows, the former is that of which our experience is the earlier and more intimate, being suggested to us by our consciousness of willing and doing. The latter of the two requires a discrimination and exactness of thought for its apprehension, which implies special mental training; else, how do we learn to call food the cause of refreshment, but day never the cause of night, though night follows day more surely than refreshment follows food? Starting, then, from experience, I consider a cause to be an effective will; and, by the doctrine of causation, I mean the notion, or first principle, that all things come of effective will; and the reception or presumption of this notion is a notional assent.

      6. As to causation in the second sense (viz. an ordinary succession of antecedents and consequents, or what is called the Order of Nature), when so explained, it falls under the doctrine of general laws; and of this I proceed to make mention, as another first principle or notion, derived by us from experience, and accepted with what I have called a presumption. By natural law I mean the fact that things happen uniformly according to certain circumstances, and not without them and at random: [pg 069] that is, that they happen in an order; and, as all things in the universe are unit and individual, order implies a certain repetition, whether of things or like things, or of their affections and relations. Thus we have experience, for instance, of the regularity of our physical functions, such as the beating of the pulse and the heaving of the breath; of the recurring sensations of hunger and thirst; of the alternation of waking and sleeping, and the succession of youth and age. In like manner we have experience of the great recurring phenomena of the heavens and earth, of day and night, summer and winter. Also, we have experience of a like uniform succession in the instance of fire burning, water choking, stones falling down and not up, iron moving towards a magnet, friction followed by sparks and crackling, an oar looking bent in the stream, and compressed steam bursting its vessel. Also, by scientific analysis, we are led to the conclusion that phenomena, which seem very different from each other, admit of being grouped together as modes of the operation of one hypothetical law, acting under varied circumstances. For instance, the motion of a stone falling freely, of a projectile, and of a planet, may be generalized as one and the same property, in each of them, of the particles of matter; and this generalization loses its character of hypothesis, and becomes a probability, in proportion as we have reason for thinking on other grounds that the particles of all matter really move and act towards each other in one certain way in relation to space and time, and not in half a dozen ways; that is, that nature acts by uniform laws. And thus we advance to the general [pg 070] notion or first principle of the sovereignty of law throughout the universe.

      There are philosophers who go farther, and teach, not only a general, but an invariable, and inviolable, and necessary uniformity in the action of the laws of nature, holding that every thing is the result of some law or laws, and that exceptions are impossible; but I do not see on what ground of experience or reason they take up this position. Our experience rather is adverse to such a doctrine, for what concrete fact or phenomenon exactly repeats itself? Some abstract conception of it, more perfect than the recurrent phenomenon itself, is necessary, before we are able to say that it has happened even twice, and the variations which accompany the repetition are of the nature of exceptions. The earth, for instance, never moves exactly in the same orbit year by year, but is in perpetual vacillation. It will, indeed, be replied that this arises from the interaction of one law with another, of which the actual orbit is only the accidental issue, that the earth is under the influence of a variety of attractions from cosmical bodies, and that, if it is subject to continual aberrations in its course, these are accounted for accurately or sufficiently by the presence of those extraordinary and variable attractions:—science, then, by its analytical processes sets right the primâ facie confusion. Of course; still let us not by our words imply that we are appealing to experience, when really we are only accounting, and that by hypothesis, for the absence of experience. The confusion is a fact, the reasoning processes are not facts. The extraordinary attractions assigned to account [pg 071] for our experience of that confusion are not themselves experienced phenomenal facts, but more or less probable hypotheses, argued out by means of an assumed analogy between the cosmical bodies to which those attractions are referred and falling bodies on the earth. I say “assumed,” because that analogy (in other words, the unfailing uniformity of nature) is the very point which has to be proved. It is true, that we can make experiment of the law of attraction in the case of bodies on the earth; but, I repeat, to assume from analogy that, as stones do fall to the earth, so Jupiter, if let alone, would fall upon the earth and the earth upon Jupiter, and with certain peculiarities of velocity on either side, is to have recourse to an explanation which is not necessarily valid, unless nature is necessarily uniform. Nor, indeed, has it yet been proved, nor ought it to be assumed, even that the law of velocity of falling bodies on the earth is invariable in its operation; for that again is only an instance of the general proposition, which is the very thesis in debate. It seems safer then to hold that the order of nature is not necessary, but general in its manifestations.

      But, it may be urged, if a thing happens once, it must happen always; for what is to hinder it? Nay, on the contrary, why, because one particle of matter has a certain property, should all particles have the same? Why, because particles have instanced the property a thousand times, should the thousand and first instance it also? It is primâ facie unaccountable that an accident should happen twice, not to speak of its happening always. If we expect a thing to happen twice, it is because we think [pg 072] it is not an accident, but has a cause. What has brought about a thing once, may bring it about twice. What is to hinder its happening? rather, What is to make it happen? Here we are thrown back from the question of Order to that of Causation. A law is not a cause, but a fact; but when we come to the question of cause, then, as I have said, we have no experience of any cause but Will. If, then, I must answer the question, What is to alter the order of nature? I reply, That which willed it;—That which СКАЧАТЬ
