[102] The theory maintained so powerfully and with such high intellectual resources by the author, that Belief is but an inseparable association, will be examined at length in a [note] at the end of the chapter. Meanwhile let it be remarked, that the case of supposed inseparable association given in this passage, requires to be qualified in the statement. We cannot, indeed, think of a stone let go in the air, without having the idea of its falling; but this association is not so strictly inseparable as to disable us from having the contrary idea. There are analogies in our experience which enable us without difficulty to form the imagination of a stone suspended in the air. The case appears to be one in which we can conceive both opposites, falling and not falling; the incompatible images not, of course, combining, but alternating in the mind. Which of the two carries belief with it, depends on what is termed Evidence.—Ed.

Where the sequence of two events is merely casual, it passes speedily away from the mind; because it is not associated with the idea of any thing in which we are interested. The things in which we are interested, are the immediate antecedents of our pleasures and pains, and the ideas of them are all inseparably associated with constant conjunctions. The association of the ideas of a constant antecedent and consequent, therefore, has both causes of strength, the interesting nature of the ideas, and the frequency of conjunction, both at their greatest height. It follows, that it should be the most potent and inseparable of all the combinations in the mind of man.

As we are thus incessantly, and thus intensely, occupied with cases of constant conjunction, while cases of casual conjunction pass slightly over the mind, and 365 quickly vanish from our consciousness, every event calls up the idea of a constant antecedent. The association is so strong, that the combination is necessary and irresistible. It often enough, indeed, happens, that we do not know the constant antecedent of an event. But never does it fail to call up the idea of such an antecedent; and so inseparably, that we can as little have and not have the idea of an event, as we can have the idea of it, and not have the idea of an inseparable antecedent along with it.—Ignorant, sometimes, of the constant antecedents of such and such events, we find them out by subsequent inquiry. Those cases of successful investigation still further strengthen the association. All that we call good, and all that we call evil, depend so entirely upon those constant conjunctions, that we are necessarily under the strongest stimulus to find them out, and to trace them with greater and greater accuracy. Thus we very often find a constancy of sequence, in which we acquiesce for a while; but after a time discover, that though constant, indeed, it is not immediate; for, that between the event and supposed antecedent, several antecedents intervene. At first we regard the ignition of the gunpowder, as the immediate antecedent of the motion of the ball. Better instructed, we find that a curious process intervenes. The constancy of the sequence is always more certain, the more nearly immediate the antecedent is. And so frequent is our detection of antecedents, more immediate than those which we have just observed, that an association is formed between the idea of every antecedent, and that of another antecedent, as yet unknown, intermediate between it and the consequent which we 366 know. In no sequence do we ever feel satisfied that we have discovered all. We see a spark ignite the gunpowder, we see one billiard-ball impel another. Though we consider these as constant antecedents and consequents, the idea of something intermediate is irresistibly conjoined. To this, though wholly unknown, we annex a name, that we may be able to speak of it. The name we have invented for this purpose is POWER. Thus, we conceive that it is not the spark which ignites the gunpowder, but the power of the spark; it is not one billiard-ball that moves the other, but the power of the ball. The Power, in this case, is a supposed consequent of the moving ball, and antecedent of the moved; and so in all other cases.

But the idea of an event does not call up the idea of its constant antecedent in closer and more intense association, than it calls up that of its consequent or consequents. I cannot have the idea of water, without the idea of its mobility, its weight, and other obvious properties. I cannot have the idea of rhubarb, without the idea of its nauseous taste, and other familiar properties. I cannot have the idea of the stroke of a sword upon the head of a man, without the idea of a wound inflicted on his head. I cannot have the idea of my falling from a ship into the middle of the sea, without the idea of my being drowned. I cannot have the idea of my falling from the top of a high tower, without having the idea of my being killed by the fall. If I have the first idea, the second forces itself upon me. The union has in it all that I mark by the word necessity; a sequence, constant, immediate, and inevitable.

This great law of our nature shews to us 367 immediately in what manner our idea of the future is generated. Night has regularly been followed by morning. The idea of night is followed by that of morning; the idea of morning is followed by that of the events of the morning, the gradual increase of light, the occupations of men, the movements of animals and objects, and all their several successions from morning till night. This is the idea of to-morrow; to this succeeds another to-morrow; and an indefinite number of these to-morrows makes up the complex idea of futurity.

But I am told, that we have not only the idea of to-morrow, but the belief of to-morrow; and I am asked what that belief is. I answer, that you have not only the idea of to-morrow, but have it inseparably. It will also appear, that wherever the name belief is applied, there is a case of the indissoluble association of ideas. It will further appear, that, in instances without number, the name belief is applied to a mere case of indissoluble association; and no instance can be adduced in which any thing besides an indissoluble association can be shewn in belief.[103] It would seem 368 to follow from this, with abundant evidence, that the whole of my notion of to-morrow, belief included, is nothing but a case of the inevitable sequence of ideas.

[103] The case that is most thoroughly opposed to the theory of indissoluble association is our belief in the Uniformity of Nature. Our overweening tendency to anticipate the future from the past is shown prior to all association; the first effect of experience is to abridge and modify a strong primitive urgency. There is, no doubt, a certain stage when association co-operates to justify the believing state. After our headlong instinct has, by a series of reverses, been humbled and toned down, and after we have discovered that the uniformity, at first imposed by the mind upon everything, applies to some things and not to others, we are confirmed by our experience in the cases where the uniformity prevails; and the intellectual growth of association counts for a small part of the believing impetus. Still, the efficacy of experience is perhaps negative rather than positive; it saves, in certain cases, the primitive force of anticipation from the attacks made upon it in the other cases where it is contradicted by the facts. It does not make belief, it conserves a pre-existing belief. (See [Note] at the end of the chapter.)—B.

This, however, is a part of our constitution, of so much importance, that it must be scrutinized with more than ordinary minuteness.

Our first assertion was, that in every instance of belief, there is indissoluble association of the ideas. We shall confine our examples, for the present, to that case of belief which is more immediately under our examination; belief in the future. I believe, that if I put my finger in the flame of the candle, I shall feel the pain of burning. I believe, that if a stone is dropped in the air, it will fall to the ground. It is evident that in these cases, the belief consists in uniting two events, the antecedent, and the consequent. There are in it, therefore, two ideas, that of the antecedent, and that of the consequent, and the union of those ideas. The previous illustrations have abundantly shewn us, in what manner the two ideas are united by association, and indissolubly united. These ingredients in the belief are all indisputable. That there is any other cannot be shewn.

369 Our second assertion was, that cases of indissoluble association, admitted by all men to be this, and nothing more, are acknowledged as Belief. The facts (which any one may call to recollection), in proof of this assertion, deserve the greatest attention; they shew the mode of investigating some of the most latent combinations of the human mind.
