It was expected that the precision of this fractionation method would prove Marbe’s conclusions wrong, and that the consciousness of thinking would be found in Watt's third period, the period of the search for the word that would suit the particular constrained association. But nothing of the sort happened. It was the third period that was introspectively blank. What seemed to be happening was that thinking was automatic and not really conscious once a stimulus word had been given, and, previous to that, the particular type of association demanded had been adequately understood by the observer. This was a remarkable result. Another way of saying it is that one does one’s thinking before one knows what one is to think about. The important part of the matter is the instruction, which allows the whole business to go off automatically. This I shall shorten to the term struction, by which I mean it to have the connotation of both instruction and construction.18

Thinking, then, is not conscious. Rather, it is an automatic process following a struction and the materials on which the struction is to operate.

But we do not have to stay with verbal associations; any type of problem will do, even those closer to voluntary actions. If I say to 18 The terms set, determining tendency, and struction need to be distinguished. A set is the more inclusive term, being an engaged aptic structure which in mammals can be ordered from a general limbic component of readiness to a specific cortical component of a determining tendency, the final part of which in humans is often a struction.

myself, I shall think about an oak in summer, that is a struction, and what I call thinking about is really a file of associated images cast up on the shores of my consciousness out of an unknown sea, just like the constrained associations in Watt's experiment.

If we have the figures 6 and 2, divided by a vertical line, 6|2, the ideas produced by such a stimulus will be eight, four, or three, according to whether the struction prescribed is addition, subtraction, or division. The important thing is that the struction itself, the process of addition, subtraction, or division, disappears into the nervous system once it is given. But it is obviously there

‘in the mind’ since the same stimulus can result in any of three different responses. And that is something we are not in the least aware of, once it is put in motion.

Suppose we have a series of figures such as the following: What is the next figure in this series? How did you arrive at your answer? Once I have given you the struction, you automatically

‘see’ that it is to be another triangle. I submit that if you try to introspect on the process by which you came up with the answer you are not truly retrieving the processes involved, but inventing what you think they must have been by giving yourself another struction to that effect. In the task itself, all you were really conscious of was the struction, the figures before you on the page, and then the solution.

Nor is this different from the case of speech which I mentioned earlier. When we speak, we are not really conscious either of the search for words, or of putting the words together into phrases, or of putting the phrases into sentences. We are only conscious of the ongoing series of structions that we give ourselves, which then, automatically, without any consciousness whatever, result in speech. The speech itself we can be conscious of as it is

produced if we wish, thus giving some feedback to result in further structions.

So we arrive at the position that the actual process of thinking, so usually thought to be the very life of consciousness, is not conscious at all and that only its preparation, its materials, and its end result are consciously perceived.

Consciousness Not Necessary for Reason

The long tradition of man as the rational animal, the tradition that enthroned him as Homo sapiens, rests in all its pontifical generality on the gracile assumption that consciousness is the seat of reason. Any discussion of such an assumption is embarrassed by the vagueness of the term reason itself. This vagueness is the legacy we have from an older ‘faculty’ psychology that spoke of a ‘faculty’ of reason, which was of course situated ‘in’

consciousness. And this forced deposition of reason and consciousness was further confused with ideas of truth, of how we ought to reason, or logic — all quite different things. And hence logic was supposed to be the structure of conscious reason confounding generations of poor scholars who knew perfectly well that syllogisms were not what was on their side of introspection.

Reasoning and logic are to each other as health is to medicine, or — better — as conduct is to morality. Reasoning refers to a gamut of natural thought processes in the everyday world. Logic is how we ought to think if objective truth is our goal — and the everyday world is very little concerned with objective truth.

Logic is the science of the justification of conclusions we have reached by natural reasoning. My point here is that, for such natural reasoning to occur, consciousness is not necessary. The very reason we need logic at all is because most reasoning is not conscious at all.

Consider to begin with the many phenomena we have already established as going on without consciousness which can be

called elementary kinds of reasoning. Choosing paths, words, notes, motions, the perceptual corrections in size and color constancies — all are primitive kinds of reasoning that go on without any prod, nudge, or even glance of consciousness.

Even the more standard types of reasoning can occur without consciousness. A boy, having observed on one or more past occasions that a particular piece of wood floats on a particular pond, will conclude directly in a new instance that another piece of wood will float on another pond. There is no collecting together of past instances in consciousness, and no necessary conscious process whatever when the new piece of wood is seen directly as floating on the new pond. This is sometimes called reasoning from particulars, and is simply expectation based on generalization. Nothing particularly extraordinary. It is an ability common to all the higher vertebrates. Such reasoning is the structure of the nervous system, not the structure of consciousness.

But more complex reasoning without consciousness is continually going on. Our minds work much faster than consciousness can keep up with. We commonly make general assertions based on our past experiences in an automatic way, and only as an afterthought are we sometimes able to retrieve any of the past experiences on which an assertion is based. How often we reach sound conclusions and are quite unable to justify them! Because reasoning is not conscious. And consider the kind of reasoning that we do about others’ feelings and character, or in reasoning out the motives of others from their actions. These are clearly the result of automatic inferences by our nervous systems in which consciousness is not only unnecessary, but, as we have seen in the performance of motor skills, would probably hinder the process.19

Surely, we exclaim, this cannot be true of the highest processes of intellectual thought! Surely there at last we will come to 19 Such instances were early recognized as not conscious and were called “automatic inference” or “common sense.” Discussions can be found in Sully, Mill, and other nineteenth-century psychologists.

the very empire of consciousness, where all is spread out in a golden clarity and all the orderly processes of reason go on in a full publicity of awareness. But the truth has no such grandeur. The picture of a scientist sitting down with his problems and using conscious induction and deduction is as mythical as a unicorn. The greatest insights of mankind have come more mysteriously. Helmholtz had his happy thoughts which “often enough crept quietly into my thinking without my suspecting their importance . . . in other cases they arrived suddenly, without any effort on my part . . . they liked especially to make their appearance while I was taking an easy walk over wooded hills in sunny weather !"20
