18 2. The only other relative terms applicable to simple sensations and ideas, are those which denote them as Antecedent and Consequent.
19 I have sensation red, sensation green. Why I mark them red, and green, or as “different,” has already been seen. What happens in marking them 20 as “antecedent” and “consequent” comes next to be considered.
A sensation, the moment it ceases, is gone for ever. When I have two sensations, therefore, A, and B, one first, the other following, sensation A is gone, before sensation B exists. But though sensation A is gone, its idea is not gone. Its idea, called up by association, exists along with sensation B, or the idea of sensation B. My knowing that the idea of sensation A is the idea of sensation A, is my having the idea. Having it, and knowing it, are not two things, but one and the same thing. Having the idea of sensation A, that is, having the idea of the immediate antecedent of sensation B, seems, also, to be the same thing with knowing it as the idea of that antecedent. Having sensation A, and after it sensation B, is mere sensation; and having the idea of sensation A, the immediate antecedent, called up by sensation B, the immediate consequent, is knowing it for that antecedent. The links of the train are three; 1, sensation A; 2, sensation B; 3, the idea of sensation A, in a certain order with B, called up by sensation B; and after this, NAMING.
The case appears mysterious, solely, from the want of words to express it clearly; and our confirmed habit of inattention to the process. Suppose, that 21 instead of two sensations, A and B, we have three, A, B, and C, in immediate succession. I recognise A, as the antecedent of B; B, as the antecedent of C. What is the process? The idea of sensation A, is associated with sensation B; and the idea of sensation B, is associated with sensation C. But sensation C, is not associated with the idea of sensation B solely, it is associated also with the idea of sensation A. It is associated, however, differently with the one and the other. It is associated with B immediately; it is associated with A, only through the medium of B; it calls up the idea of B, by its own associating power, and the idea of B, calls up the idea of A. This second state of consciousness is different from the first. The first is that in consequence of which B receives the name “Antecedent,” and C the name “Consequent.” When two sensations in a train are such, that, if one exists, it has the idea of the other along with it, by its immediate exciting power, and not through any intermediate idea; the sensation, the idea of which is thus excited, is called the antecedent, the sensation which thus excites that idea, is called the consequent.
It is evident that the terms, “antecedent,” and “consequent,” are not applied in consequence of sensation merely, but in consequence of sensation joined with ideas. The antecedent sensation, which is past, must be revived by the consequent sensation, which is present. It is the peculiarity of this revival which procures it the name. If revived by any other sensation, it would not have that name.
The Clock strikes three. My feelings are, three sensations of hearing, in succession. How do I know 22 them to be three successive sensations? The process in this instance does not seem to be very difficult to trace. The clock strikes one; this is pure sensation. It strikes two; this is a sensation, joined with the idea of the preceding sensation, and the idea of the feeling (also sensation), called change of sensation, or passage from one sensation to another. After two, the clock strikes three; there is, here, sensation, and a double association; the third stroke is sensation; that is associated immediately with the idea of the second, and through the idea of the second, with the idea of the first. It is observable, that these successive associations soon cease to afford distinct ideas; they hardly do so beyond the second stage. When the clock strikes, we may have distinct ideas of the strokes, as far as three, hardly farther; we must then have recourse to NAMING, and call the strokes, four, five, six, and so on: otherwise we should be wholly unable to tell how often the clock had struck.
In the preceding pairs of relative terms, we have found only one name for each pair. Thus, when we say of A and B, that A is similar to B, we say also, that B is similar to A. We have now an instance of a pair of relative terms, consisting not of the same, but of different names. If we call A antecedent, we call B consequent. The first class were called by the ancient logicians, synonymous, the second heteronymous; we may call them more intelligibly, single-worded, and double-worded, relatives.[7]
[7] The next relation which the author examines is that of succession, or Antecedent and Consequent. And here again we have one of the universal conditions to which all our feelings or states of consciousness are subject. Whenever we have more feelings than one, we must have them either simultaneously or in succession; and when we are conscious of having them in succession, we cannot in any way separate or isolate the succession from the feelings themselves. The author attempts to carry the analysis somewhat farther. He says that when we have two sensations in the order of antecedent and consequent, the consequent calls up the idea of the antecedent; and that this fact, that a sensation calls up the idea of another sensation directly, and not through an intermediate idea, constitutes that other sensation the antecedent of the sensation which reminds us of it—is not a consequence of the one sensation’s having preceded the other, but is literally all we mean by the one sensation’s having preceded the other. There seem to be grave objections to this doctrine. In the first place, there is no law of association by which a consequent calls up the idea of its antecedent. The law of successive association is that the antecedent calls up the idea of the consequent, but not conversely; as is seen in the difficulty of repeating backwards even a form of words with which we are very familiar. We get round from the consequent to the antecedent by an indirect process, through the medium of other ideas; or by going back, at each step, to the beginning of the train, and repeating it downwards until we reach that particular link. When a consequent directly recalls its antecedent, it is by synchronous association, when the antecedent happens to have been so prolonged as to coexist with, instead of merely preceding, the consequent.
The next difficulty is, that although the direct recalling of the idea of a past sensation by a present, without any intermediate link, does not take place from consequent to antecedent, it does take place from like to like: a sensation recalls the idea of a past sensation resembling itself, without the intervention of any other idea. The author, however, says, that “when two sensations in a train are such that if one exists, it has the idea of the other along with it by its immediate exciting power, and not through any intermediate idea; the sensation, the idea of which is thus excited, is called the antecedent, the sensation which thus excites that idea is called the consequent.” If this therefore were correct, we should give the names of antecedent and consequent not to the sensations which really are so, but to those which recall one another by resemblance.
Thirdly and lastly, to explain antecedence, i.e. the succession between two feelings, by saying that one of the two calls up the idea of the other, that is to say, is followed by it, is to explain succession by succession, and antecedence by antecedence. Every explanation of anything by states of our consciousness, includes as part of the explanation a succession between those states; and it is useless attempting to analyse that which comes out as an element in every analysis we are able to make. Antecedence and consequence, as well as likeness and unlikeness, must be postulated as universal conditions of Nature, inherent in all our feelings whether of external or of internal consciousness.—Ed.
