“For a long time,” says he, “both philosophers and physiologists, as well as physicians, have contended that the brain is the organ of the soul.”[2] The opinion that the brain, (as a whole, or such and such parts of the brain considered separately,) is the seat of the soul, is, in fact, as old as learning itself. Descartes placed the soul in the pineal gland, Willis in the corpora striata, Lapeyronie in the corpus callosum, &c. &c.

As to the more recent authorities, Gall quotes Sœmmerring, who says precisely that, “the brain is the exclusive instrument of all sensation, all thought, and all will,”[3] &c. He quotes Haller, who proves (proves is the very expression made use of by Gall himself,) that “sensation does not take place at the point where the object touches the nerve, the point where the impression is made, but in the brain.”[4] He might have quoted many other authorities to the same effect.

Were not Cabanis’s writings anterior to the time of Gall? and did not he say, “In order to obtain a just idea of those operations whose result is thought, the brain must be considered as a peculiar organ designed to produce it, just as the stomach and the bowels are designed to produce digestion, the liver to secrete the bile,” &c.?[5] a proposition so extravagant as to become almost ridiculous, but which is in truth the very proposition of Gall himself, except as to some exaggeration in the terms employed.
