Extract

An Essay in the Journal of Mental Science for October, 1875, entitled, “Can Unconscious Cerebration be Proved ?” by Dr. Ireland, Superintendent of the Institution for the Education of Imbeciles at Larbert, ends thus:—“In any case the theory of ‘unconscious cerebration’ derives no support from physiology. It is a child of the old metaphysics, to be brought forward and repelled by the study and analysis of mental operations, cognisable by internal examination.”

I may properly remark here, as to this correspondence, that Forbes did not send the letters to me as being “private and confidential,” but in his public capacity as Editor of the “Brit, and For. Med. Beview,” in which my essay was to appear, and with the request that I should point out in what particulars my views differed from those of Dr. Carpenter, with a view to publication with the Essay. I wrote an addendum in compliance with this request, which now lies before me, but Forbes did not publish it.Google Scholar
