The forgotten Idea is an Idea associated, as cause, with the end to be obtained by it, as its effect. The same is the case with the ideas which the composer of a discourse selects out of the multitudes, which the continual suggestions of the interesting Idea by which he is actuated, that of his end, bring before him. The greater number are not associated with the idea of his end as cause and effect. Some among them are. These immediately suggest the use to be made of them; and thence, by the regular chains of association, the operations take place.
It is from these explanations, also, easy to see what constitutes the difference between the man who composes a coherent, and the man who composes a rambling discourse. In the man who composes the coherent discourse, the main Idea, that of the end in view, predominates, and controls the association, in every part of the process. It is not only the grand suggesting principle, which sets trains of the ideas connected with itself in motion; but it is the grand selecting principle. As ideas rise in the train, this interesting and predominating idea stands ready to be associated as effect with every idea in the train which can operate as cause; it so associates itself with no other; and therefore no wrong selection is made. 372 If, however, it does not thus predominate in the mind of the composer of the discourse, as his exclusive end; if it gives way at every turn to some other end; as the idea of applause from some lively jest, from some gaudy description, from some florid thought, the selection is made so far upon other principles, and the object of the discourse is forgotten.[66]
[66] The account here given of Attention, though full of instructive matter, I cannot consider to be at all adequate. When it is said that a sensation, by reason of its highly pleasurable or painful character, engrosses the mind, more is meant than merely that it is a highly pleasurable or painful sensation. The expression means, first, that when a sensation is highly pleasurable or painful, it tends, more or less strongly, to exclude from consciousness all other sensations less pleasurable or painful than itself, and to prevent the rising up of any ideas but those which itself recals by its associations. This portion of the facts of the case is noticed by the author, though not sufficiently prominent in his theory. But there is another portion, altogether untouched by him. Through this power which the sensation has, of excluding other sensations and ideas, it tends to prolong its own existence; to make us continue conscious of it, from the absence of other feelings which if they were present would either prevent us from feeling it, or would make us feel it less intensely; which is called diverting our attention from it. This is what we mean when we say that a pleasurable or painful idea tends to fix the attention. We mean, that it is not easy to have, simultaneously with it, any other sensation or idea; except the ideas called up by itself, and which in turn recal it by association, and so keep it present to the mind. Becoming thus a nearly exclusive object of consciousness, it is both felt with greater intensity, and acquires greater power of calling up, by association, other ideas. There is an increase both in the multitude, the intensity, and the distinctness of the ideas it suggests; as is always the case when the suggesting sensation or idea is increased in intensity. In this manner a sensation which gets possession of our consciousness because it is already intense, becomes, by the fact of having taken possession, still more intense, and obtains still greater control over the subsequent train of our thoughts. And these also are precisely the effects which take place when, the sensation not being so pleasurable or painful as to produce them of itself, or in other words to fix the attention, we fix it voluntarily. All this is as true of Ideas as of Sensations. If a thought is highly painful, or pleasurable, it tends to exclude all thoughts which have no connexion with it, and which if aroused would tend to expel it—to make us (as we say) forget the pain or the pleasure. By thus obtaining exclusive possession of the mind, the pleasurable or painful thought is made more intense, more painful or pleasurable; and, as is the nature of pains and pleasures, acquires, in consequence, a greater power of calling up whatever ideas are associated with it. All this is expressed by saying that it fixes the attention. And ideas which are not of themselves so painful or pleasurable as to fix the attention, may have it fixed on them by a voluntary act. In other words, the will has power over the attention.
But how is this act of will excited, and in what does it consist? On this point the author’s analysis is conclusive, and admirable. The act, like other voluntary acts, is excited by a motive; by the desire of some end, that is, of something pleasurable; (including in the word pleasurable, as the author does, exemption from pain). What happens is, that, the idea on which we are said to fix our attention not being of itself sufficiently pleasurable to fix it spontaneously, we form an association between it and another pleasurable idea, and the result then is that the attention is fixed. This is the true account of all that we do when we fix our attention voluntarily; there is no other possible means of fixing it. It thus appears, that the fixing of attention by an act of will depends on the same law, as the fixing it by the natural pleasantness or painfulness of the idea. Of itself the idea is not pleasant or painful, or not sufficiently so to fix the attention; but if it were considerably more pleasant or painful than it is, it would do so. It becomes considerably more pleasurable by being associated with the motive—that is, by a fresh association of pleasure with it—and the attention is fixed. This explanation seems complete.
It may be said, however, by an objector, that this accounts only for the case in which the voluntary attention flows easy and unimpeded, almost as if it were spontaneous; when the mere perception that the idea is connected with our purpose—with the pleasurable end which suggested the train of thought, at once and without difficulty produces that exclusive occupation of the mind with it, which is called fixing the attention. But it often happens that the mere perception of its connexion with our purpose is not sufficient: the mind still wanders from the thought: and there is then required a supplementary force of will, in aid of association; an effort, which expends energy, and is often both painful and exhausting.
Let us examine, then, what takes place in this case. The association of the thought with the pleasurable end in view, is sufficient to influence the attention, but not sufficient to command it. The will, therefore, has to be called in, to heighten the effect. But in this case, as in every case, the will is called into action by a motive. The motive, like all other motives, is a desire. The desire must be either the same desire which was already felt, but made more effectual than before, or another desire superadded to the first. The former case presupposes the latter: for the desire which was not sufficient to fix the attention firmly on that which is the means to its fulfilment, cannot be sufficient to call forth the voluntary effort necessary for fixing it: some other desire must come to its assistance. What, then, is this other desire? The question is not difficult. The present is one of the complex cases, in which we desire a different state of our own desires. By supposition, we do not care enough for the immediate end, that is the idea of it is not sufficiently pleasurable, or the idea of its frustration sufficiently painful, to exert the force of association required. But we are dissatisfied with this infirmity of our desires: we wish that we cared more for the end; we think that it would be better for us if either this particular end, or our ends generally, had greater command over our thoughts and actions than they have. There is thus called up, by our sense of the insufficiency of our attention in the particular case, the idea of another desirable end—greater vigour and certainty in our mental operations. That idea superadds itself to the idea of the immediate end, and this reinforcement of the associating power at last suffices to fix the attention. Or (which is the same thing in effect) the painful idea is called up, of being unable to fix our attention, and being in consequence thwarted generally in our designs; and this pain operates, in the same manner as a pleasure, in fixing our attention upon the thought which, if duly attended to, will relieve us from the oppressive consciousness.
It will be asked, whence come the sense of laborious effort, and the subsequent feeling of fatigue, which are experienced when the attention does not fix itself spontaneously, but is fixed with more or less difficulty by a voluntary act? I conceive them to be consequences of the prolongation of the state designated by the author, in the text, as a state of unsatisfied desire. That state, whatever view the psychologist takes of it, is a condition of the brain and nerves, having physiological consequences of great importance, and drawing largely on that stock of what we call nervous energy, any unusual expenditure or deficiency of which produces the feeling of exhaustion. The waste of energy, and the subsequent exhaustion, are greatest when the desire seems continually on the point of obtaining its gratification, but the gratification constantly eludes it. And this is what actually happens in the case supposed. The attention continually fastens on the idea which we desire to attend to, but, from the insufficient strength of the pleasurable or painful association, again deserts it; and the incessant alternation of hope and disappointment produces, as in other cases, the nervous disturbance which we call the sense of effort, and which is physiologically followed by the sensations of nervous exhaustion. It is probable that whatever is not muscular in the feeling which we call a sense of effort, is the physical effect produced by a more than usual expenditure of nervous force: which, reduced to its elements, means a more than usually rapid disintegration and waste of nervous substance.
Let me here remark, that the recognition, by the author of the Analysis, of a peculiar state of consciousness called a state of unsatisfied desire, conflicts with his doctrine that desire is nothing but the idea of the desired pleasure as future. In what sense is it possible to speak of an unsatisfied idea? If even we insert the omitted element of Belief, and resolve desire not into the mere idea, but into the expectation of a pleasure; though we might rationally speak of an unsatisfied expectation, it would only mean an expectation not fulfilled, in other words, an expectation of pleasure not followed by the pleasure; an expectation followed by a mere negation. How a pleasant idea, followed, not by a pain, but by nothing at all, is converted into a pain, the pain of unsatisfied desire, remains to be explained: and the author has not pointed out any associations which account for it. If it be said that the expectation is perpetually renewed and perpetually disappointed, this is true, but does not account for more than a continual alternation between a pleasant idea and no idea at all. That an element of pain should enter into unsatisfied desire, is a fact not explained by the author’s theory; and it stands as evidence that there is in a desire something inherently distinct from either an idea or an expectation.—Ed.
373 I cannot deem it necessary, after the training which we now have had, to give these expositions in more 374 minute detail. But it seems to be proper to notice, in a few words, the explanation which they afford of 375 the phenomena which are usually named the power or want of power over the train of the ideas—in a still 376 more important instance than the composition of a discourse, that of the conduct of life. Some men are distinguished for a steady direction of their actions, through the course of their lives, to some general end, or ends. One man attaches himself to the cultivation of his mind; another, to the accumulation of wealth; another, to the acquisition of fame. There are other men whose lives appear to be a perpetual fluctuation. They either shift from one great end to another perpetually; or, in their trains, the great ends appear to have no ascendancy over the little. There are men who seem to have a different end of their actions, every day they rise from their beds. The men, in whose minds the great purposes of life seem to have no greater ascendancy than the minor objects, are called frivolous men. It sometimes happens, that a 377 man who chooses a frivolous end is steady in the pursuit of it. The common case, however, is that no one frivolous end acquires a steady ascendancy; and the man is in a state of perpetual fluctuation.
The solution of these phenomena is obvious. When the idea of any of the great purposes of life exists habitually in controlling strength, it performs the same function in regard to the selection of actions, which the Idea of the end or purpose of the Discourse performs in regard to ideas, in the case of the man who is composing it. Out of the whole number of ideas, which present themselves to him, the idea of his End associates itself with those which can operate as causes of its attainment; and this association is followed by all the other associations which produce the employment of the Ideas. In like manner, when 378 the great purposes of life are established into predominating ideas, they associate themselves strongly with the ideas of those actions which contribute to their attainment; and those associations are followed by all the other associations, which produce their adoption.
