However, this assent is notional, because we generalize a consistent, methodical form of Divine Unity and Personality with Its attributes, from particular experiences of the religious instinct, which are themselves, only intensivè, not extensivè, and in the imagination, not intellectually, notices of Its Presence; though at the same time that assent may become real of course, as may the assent to the external world, viz. when we apply our general knowledge to a particular instance of that knowledge, as, according to a former remark, the general [pg 064] “varium et mutabile” was realized in Dido. And in thus treating the origin of these great notions, I am not forgetting the aid which from our earliest years we receive from teachers, nor am I denying the influence of certain original forms of thinking or formative ideas, connatural with our minds, without which we could not reason at all. I am only contemplating the mind as it moves in fact, by whatever hidden mechanism; as a locomotive engine could not move without steam, but still, under whatever number of forces, it certainly does start from Birmingham and does arrive in London.
4. And so again, as regards the first principles expressed in such propositions as “There is a right and a wrong,” “a true and a false,” “a just and an unjust,” “a beautiful and a deformed;” they are abstractions to which we give a notional assent in consequence of our particular experiences of qualities in the concrete, to which we give a real assent. As we form our notion of whiteness from the actual sight of snow, milk, a lily, or a cloud, so, after experiencing the sentiment of approbation which arises in us on the sight of certain acts one by one, we go on to assign to that sentiment a cause, and to those acts a quality, and we give to this notional cause or quality the name of virtue, which is an abstraction, not a thing. And in like manner, when we have been affected by a certain specific admiring pleasure at the sight of this or that concrete object, we proceed by an arbitrary act of the mind to give a name to the hypothetical cause or quality in the abstract, which excites it. We speak of it as beautifulness, and henceforth, when we call a thing beautiful, we [pg 065] mean by the word nothing else than a certain quality of things which creates in us this special sensation.
These so-called first principles, I say, are really conclusions or abstractions from particular experiences; and an assent to their existence is not an assent to things or their images, but to notions, real assent being confined to the propositions directly embodying those experiences. Such notions indeed are an evidence of the reality of the special sentiments in particular instances, without which they would not have been formed; but in themselves they are abstractions from facts, not elementary truths prior to reasoning.
I am not of course dreaming of denying the objective existence of the Moral Law, nor our instinctive recognition of the immutable difference in the moral quality of acts, as elicited in us by one instance of them. Even one act of cruelty, ingratitude, generosity, or justice reveals to us at once intensivè the immutable distinction between those qualities and their contraries; that is, in that particular instance and pro hac vice. From such experience—an experience which is ever recurring—we proceed to abstract and generalize; and thus the abstract proposition “There is a right and a wrong,” as representing an act of inference, is received by the mind with a notional, not a real assent. However, in proportion as we obey the particular dictates which are its tokens, so are we led on more and more to view it in the association of those particulars, which are real, and virtually to change our notion of it into the image of that objective fact, which in each particular case it undeniably is.
5. Another of these presumptions is the belief in [pg 066] causation. It is to me a perplexity that grave authors seem to enunciate as an intuitive truth, that every thing must have a cause. If this were so, the voice of nature would tell false; for why in that case stop short at One, who is Himself without cause? The assent which we give to the proposition, as a first principle, that nothing happens without a cause, is derived, in the first instance, from what we know of ourselves; and we argue analogically from what is within us to what is external to us. One of the first experiences of an infant is that of his willing and doing; and, as time goes on, one of the first temptations of the boy is to bring home to himself the fact of his sovereign arbitrary power, though it be at the price of waywardness, mischievousness, and disobedience. And when his parents, as antagonists of this wilfulness, begin to restrain him, and to bring his mind and conduct into shape, then he has a second series of experiences of cause and effect, and that upon a principle or rule. Thus the notion of causation is one of the first lessons which he learns 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
