"III. The General Function of Mind and Brain. (1) The generic function of Mind, as of the nervous system, is correlation (2) The special organ for effecting fresh correlation is consciousness. (3) The deliverances of consciousness arise from stimuli acting upon structures built up by experience, (4) on foundations laid by heredity, (5) which supplies not only specific adaptations, but a background to the entire life of consciousness." It would be hard to find a more concise, complete, and timely formularization of the seeming trend of present resultants in this particular direction than these sentences set forth for whomsoever will ponder each carefully-built statement and really understand what it means as part of a system. "Mind is the permanent unity including consciousness and the sum of processes continuous with consciousness and determining it. These processes involve, but are not identical with, physical processes, constituting with them a psychophysical unity,"--this quotation might almost serve as the motto of early Twentieth Century scientific philosophy. It seems to the present reviewer to have almost as much philosophy in it as Harold Hoffding's well-known sentence has of psychology: ("the unity of mental life has its expression not only in memory and synthesis, but also in a dominant fundamental feeling, characterized by the contrast between pleasure and pain, and in an impulse, springing from this fundamental feeling, to movement and activity"). It might be the creed of the Neoidealism. Hobhouse's discussion of mechanism in relation to teleology and to the universal harmony and reality is fairly representative of the drift of thought as set forth by recent English and French writers such as J. S. Haldane, Oliver Lodge and some of the prominent biologists, and by Henri Bergson: "An organic whole is therefore like a machine in being purposive, though unlike it in that its purpose is within." "A purposive process is one determined by its tendency to produce a certain result, purpose itself being an act [sic] determined in its character by that which it tends to bring about. As such it differs fundamentally from a mechanical cause." "The empirical and philosophical arguments point to the same general conclusion, that reality is the process of the development of Mind." As a guide to one's thinking, and as integrators of one's subconscious intuitions and resultants, such concise formulae certainly have much value, especially when, as here, clearly and ably expounded in the text proper.
