![the brain to the corresponding facts of consciousness is un- thinkable. Granted that a definite thought and a definite molecular action in the brain occur simultaneously, we do not possess the intellectual organ, nor apparently any rudiment of the organ, which would enable us to pass by a process of rea- soning from the one phenomenon to the other. They appear together, we know not why.” This quotation ms given by Lewes, in his “Problems of Life and Mind,” Vol. 2, p.458. Lewes adds—“ To the same effect. Mill : Logic, ii., 436. Du Bois Reymond : iiber die Grenzen des Naturerkennens, 1872, p. 17. Griesinger: Maladies Mentales, 1865, p. 7. Donders in the Archiv fur Anat. u. Physiol, 1868, p. 658. Lotze, Mikrokoimus, 1856, 1, 161.” Mr. Lewes differs, as the following quotation serves to shew :—“ That the passage of a motion into a sensation is unthinkable, and that by no intelligible process can we follow the transformation, I admit; but I do not admit that there is any such transformation. When I am told that a nervous excitation is transformed into a sensation on reaching the brain, I ask, who knows this ? On what evidence is this fact asserted ? On examination it will appear that there is no evidence at all of such a transformation; all the evidence points to the very different fact that the neural process and the feeling are one and the same process viewed under different aspects. [Not italics in original.] Viewed from the physical or objective side, it is a neural process; viewed from the psycho- logical or subjective side, it is a sentient process.” (Problems of Life and Mind, Vol. 2, p. 459.) Mr. Lewes’s view does not conflict with mine in this inquiry * For all I have to urge in this paper is, that we should try to determine the anatomical nature of the neural arrangement, and this can be done regardless of any hypothesis as to the * Mr. Lewes, under the head Psychological Spectrum, writes : “ Every psychical fact is a product of sense work, brain work, and muscle work.” (Problems &c Vol. i, p. 147.)](https://iiif.wellcomecollection.org/image/b22355078_0015.jp2/full/800%2C/0/default.jpg)
