Popular passages
Page 20 - If these positions are well based, it follows that our mental conditions are simply the symbols in consciousness of the changes which take place automatically in the organism ; and that, to take an extreme illustration, the feeling we call volition is not the cause of a voluntary act, but the symbol of that state of the brain which is the immediate cause of that act.

Page 497 - But as young men, when they knit and shape perfectly, do seldom grow to a further stature ; so knowledge, while it is in aphorisms and observations, it is in growth : but when it once is comprehended in exact methods, it may perchance be further polished and illustrated and accommodated for use and practice; but it increaseth no more in bulk and substance.
Page 125 - If there is some organization, it must consist in that same " physiological division of labour " in which all organization consists ; and there is no division of labour* physiological or other, but what involves the concentration of special kinds of activity in special places.
Page 9 - ... the passage from the current to the needle, if not demonstrable, is thinkable, and that we entertain no doubt as to the final mechanical solution of the problem. But the passage from the physics of the brain to the corresponding facts of consciousness is unthinkable. 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...
Page 154 - For we have it not in our power to ascertain, by any direct process, what Consciousness told us at the time when its revelations were in their pristine purity. It only offers itself to our inspection, as it exists now, when those original revelations are overlaid and buried under a mountainous heap of acquired notions and perceptions.
Page 9 - Can the oscillation of a molecule be represented in consciousness side by side with a nervous shock, and the two be recognized as one? No effort enables us to assimilate them. That a unit of feeling has nothing in common with a unit of motion, becomes more than ever manifest when we bring the two into juxtaposition.
Page 9 - We can trace the development of a nervous system, and correlate with it the parallel phenomena of sensation and thought. We see with undoubting certainty that they go hand in hand. But we try to soar in a vacuum the moment we seek to comprehend the connection between them.
Page 421 - Mind to them, in the light of ' reflex actions' of the Cerebrum, there is no more difficulty in comprehending that such reflex actions may proceed without our knowledge, so as to evolve intellectual products when their results are transmitted to the Sensorium and are thus impressed on our consciousness, than there is in understanding that impressions may excite muscular movements through the 'reflex' power' of the Spinal Cord, without the necessary intervention of Sensation.
Page 462 - Beethoven arising ; then you must admit that the genesis of the great man depends on the long series of complex influences which has produced the race in which he appears, and the social state into which that race has slowly grown.
