Brown Book: Difference between revisions

{{BBB TS reference|Ts-310,13}} a) Someone says, “I whistled [[File:Brown Book 1-13.png|70px|link=]] (whistling a tune)”; b) Someone writes, “I whistled ”. An onomatopoetic word like “rustling” may be called a pattern. We call a very great variety of processes “comparing an object with a pattern”. We comprise many kinds of symbols under the name “pattern”. In 7) B compares a picture in the table with the objects he has before him. But what does comparing a picture with the object consist in? Suppose the table shewed: a) a picture of a hammer, of pincers, of a saw, of a chisel; b) on the other hand, pictures of twenty different kinds of butterflies. Imagine what the comparison in these cases would consist in, & note the difference. Compare with these cases a third case c) where the pictures in the table represent building stones drawn to scale, & the comparing has to be done with ruler and compasses. Suppose that B's task is to bring a piece of cloth of the colour of the sample. How are the colours of sample and cloth to be compared? Imagine a series of different cases:

{{parBB|17}} Imagine on the other hand that the order has been, “Bring a material slightly darker than this sample”. In 14) I said that B fetches the material “from memory”, which is using a {{BBB TS reference|Ts-310,14}} common form of expression. But what might happen in such a case of comparing “from memory” is of the greatest variety. Imagine a few instances:

{{ParBB|14a}} B has a memory image before his mind's eye when he goes for the material. He alternately looks at materials and recalls his image. He goes through this process with, say, five of the bolts, in some instances saying to himself, “Too dark”, in some instances saying to himself, “Too light”. At the fifth bolt he stops, says, “That's it”, & takes it from the shelf.

{{ParBB|14b}} No memory image is before B's eye. He looks at four bolts, shaking his head each time, feeling some sort of mental tension. On reaching the fifth bolt, this tension relaxes, he nods his head, & takes the bolt down.

{{ParBB|14c}} B goes to the shelf without a memory image, looks at five bolts one after the other, takes the fifth bolt from the shelf.

When we call these three preceding cases cases of comparing from memory, we feel that their description is in a sense unsatisfactory, or incomplete. We are inclined to say that the description has left out the essential feature of such a process & given us accessory features only. The essential feature it seems would be what one might call a specific experience of comparing & of recognizing. Now it is queer that on closely looking at cases of comparing, it is very easy to see a great number of activities and states of mind, all ''more or less'' characteristic {{BBB TS reference|Ts-310,15}} of the act of comparing. This in fact is so, whether we speak of comparing from memory or of comparing by means of a sample before our eyes. We know a ''vast'' number of such processes, processes similar to each other in a vast number of different ways. We hold pieces whose colours we want to compare together or near each other for a longer or shorter period, look at them alternately or simultaneously, place them under different lights, say different things while we do so, have memory images, feelings of tension & relaxation, satisfaction & dissatisfaction, the various feelings of strain in and around our eyes accompanying prolonged gazing at the same object, & all possible combinations of these & many other experiences. The more such cases we observe & the closer we look at them, the more doubtful we feel about finding one particular mental experience characteristic of comparing. In fact, if after you had scrutinized a number of such ''closely'', I admitted that there existed a peculiar mental experience which you might call the experience of comparing, & that if you insisted, I should be willing to adopt the word “comparing” only for cases in which this peculiar feeling had occurred, you would now feel that the assumption of such a peculiar experience had lost its point, because this experience was placed side by side with a vast number of other experiences which after we have scrutinized the cases seems to be that which really constitutes what connects all the cases of comparing. For the “specific experience” we had been looking for was meant to have played the role which has been assumed by the mass of experiences revealed to us by our {{BBB TS reference|Ts-310,16}} scrutiny: We never wanted the specific experience to be just one among a number of ''more or less'' characteristic experiences. (One might say that there are two ways of looking at this matter, one as it were, at close quarters, the other as though from a distance and through the medium of a peculiar atmosphere.) In fact we have found that the use which we really make of the word “comparing” is different from that which looking at it from far away we were led to expect. We find that what connects all the cases of comparing is a vast number of overlapping similarities, and as soon as we see this, we feel no longer compelled to say that there must be some one feature common to them all. What ties the ship to the wharf is a rope, and the rope consists of fibres, but it does not get its strength from any fibre which runs through it from one end to the other, but from the fact that there is a vast number of fibres overlapping.

“But surely in case 14c) B acted entirely automatically. If all that happened was really what was described there, he did not know why he chose the bolt he did choose. He had no reason for choosing it. If he chose the right one, he did it as a machine might have done it”. Our first answer is that we did not deny that B in case 14c) had what we should call a personal experience, for we did not say that he didn't see the materials from which he chose or that which he chose, nor that he didn't have muscular and tactile sensations and such like while he did it. Now what would such a reason which justified his choice and made it non-automatic be like? (i.e.: What do we {{BBB TS reference|Ts-310,17}} ''imagine'' it to be like?) I suppose we should say that the opposite of automatic comparing, as it were, the ideal case of conscious comparing, was that of having a clear memory image before our mind's eye or of seeing a real sample & of having a specific feeling of not being able to distinguish in a particular way between these samples and the material chosen. I suppose that this peculiar sensation is the reason, the justification, for the choice. This specific feeling, one might say, connects the two experiences of seeing the sample, on the one hand, and the material on the other. But if so, what connects this specific experience with either? We don't deny that such an experience might intervene. But looking at it as we did just now, the distinction between automatic and non-automatic appears no longer clear-cut and final as it did at first. We don't mean that this distinction loses its practical value in particular cases, e.g., if asked under particular circumstances, “Did you take this bolt from the shelf automatically, or did you think about it?”, we may be justified in saying that we did not act automatically and give as a reason || explanation we had looked at the material carefully, had tried to recall the memory image of the pattern, & had uttered to ourselves doubts and decisions. This may ''in the particular case'' be taken to distinguish automatic from non-automatic. In another case however we may distinguish between an automatic & a non-automatic way of the appearance of a memory image, and so on.

If our case 14c) troubles you, you may be inclined to say: “But ''why'' did he bring just this bolt of material? How has he {{BBB TS reference|Ts-310,18}} recognized it as the right one? What by? ‒ ‒ If you ask “why”, do you ask for the cause or for the reason? If for the cause, it is easy enough to think up a physiological or psychological hypothesis which explains this choice under the given conditions. It is the task of the experimental sciences to test such hypotheses. If on the other hand you ask for a reason the answer is, “There need not have been a reason for the choice. A reason is a step preceding the step of the choice. But why should every step be preceded by another one?”

“But then B didn't really ''recognize'' the material as the right one”. ‒ ‒ You needn't reckon 14c) among the cases of recognizing, but if you have become aware of the fact that the processes which we call processes of recognition form a vast family with overlapping similarities, you will probably feel not disinclined to include 14c) in this family, too. ‒ ‒ “But doesn't B in this case lack the criterion by which he can recognize the material? In 14a), e.g., he had the memory image and he recognized the material he looked for by its agreement with the image”. ‒ ‒ But had he also a picture of this agreement before him, a picture with which he could compare the agreement between the pattern and the bolt to see whether it was the right one? And, on the other hand, couldn't he have been given such a picture? Suppose, e.g., that A wished B to remember that what was wanted was a bolt exactly like the sample, not, as perhaps in other cases, a material slightly darker than the pattern. Couldn't A in this case have given to B an example of the agreement required by giving him two pieces of the same colour (e.g., {{BBB TS reference|Ts-310,19}} as a kind of reminder)? Is any such link between the order & its execution necessarily the last one? ‒ ‒ And if you say that in 14b) at least he had the relaxing of the tension by which to recognize the right material, had he to have an image of this relaxation about him to recognize it as that by which the right material was to be recognized? ‒ ‒

In 1) B learnt to bring a building stone on hearing the word “column!” called out. We could imagine what happened in such a case to be this: In B's mind the word called out brought up an image of a column, say; the training had, as we should say, established this association. B takes up that building stone which conforms to his image. ‒ ‒ But was this ''necessarily'' what happened? If the training could bring it about that the idea or image – – automatically – – arose in B's mind, why shouldn't it bring about B's ''actions'' without the intervention of an image?

{{BBB TS reference|Ts-310,20}} This would only come to a slight variation of the associative mechanism. Bear in mind that the image which is brought up by the word is not arrived at by a rational process (but if it is, this only pushes our argument further back), but that this case is strictly comparable with that of a mechanism in which a button is pressed and an indicator plate appears. In fact this sort of mechanism can be used instead of that of association.
