Broca’s famous observation was in itself very simple. There had in 1831 been admitted at the Bicêtre, an insane hospital near Paris, a man whose sole defect seemed to be that he could not talk. He communicated intelligently by signs and was otherwise mentally normal. He remained at the Bicêtre for thirty years with this defect and on April 12, 1861, was put under the care of Broca, the surgeon, because of a gangrenous infection. Broca for five days subjected him to a careful examination, in which he satisfied himself that the musculature of the larynx and articulatory organs was not hindered in normal movements, that there was no other paralysis that could interfere with speech, and that the man was intelligent enough to speak. On April 17 the patient— fortunately, it must have seemed, for science—died; and within a day Broca had performed an autopsy, discovering a lesion in the third frontal convolution of the left cerebral hemisphere, and had presented the brain in alcohol to the Société d’Anthropologie.
[ Titchener ] always seemed to me the nearest approach to genius of anyone with whom I have been closely associated.… He was competent with languages, and could ad lib in Latin when the occasion required it. If you had mushrooms, he would tell you at once how they should be cooked. If you were buying oak for a new floor, he would at once come forward with all the advantages of ash. If you were engaged to be married, he would have his certain and insistent advice about the most unexpected aspects of your problems, and if you were honeymooning, he would write to remind you, as he did me, on what day you ought to be back at work.
Scientific truth, like puristic truth, must come about by controversy. Personally this view is abhorrent to me. It seems to mean that scientific truth must transcend the individual, that the best hope of science lies in its greatest minds being often brilliantly and determinedly wrong, but in opposition, with some third, eclectically minded, middle-of-the-road nonentity seizing the prize while the great fight for it, running off with it, and sticking it into a textbook for sophomores written from no point of view and in defense of nothing whatsoever. I hate this view, for it is not dramatic and it is not fair; and yet I believe that it is the verdict of the history of science.
It is not likely that the history of psychology can be written in the next three centuries without mention of Freud's name and still claim to be a general history of psychology... Perhaps, had Freud been smothered in his cradle, the times would have produced a substitute, It is hard to say. The dynamics of history lack control experiments.
I believe that robotic thinking helps precision of psychological thought, and will continue to help it until psychophysiology is so far advanced that an image is nothing other than a neural event, and object constancy is obviously just something that happens in the brain. That time is still a long way off, and in the interval I choose to sit cozily with my robot, squeezing his hand and feeling a thrill -- a scientist's thrill -- when he squeezes mine back again.
The experimental psychologist... needs historical sophistication within his own sphere of expertness. Without such knowledge he sees the present in distorted perspective, he mistakes old facts and old views for new, and he remains unable to evaluate the significance of new movements and methods. In this matter I can hardly state my faith too strongly. A psychological sophistication that contains no component of historical orientation seems to me to be no sophistication at all.
