Página 47 - Life only avails, not the having lived. Power ceases in the instant of repose ; it resides in the moment of transition from a past to a new state, in the shooting of the gulf, in the darting to an aim.
Página 18 - Biology10 has devoted a great deal of space to it and concluded that it was a function of the relation of the animal or plant to its environment. For example, an animal moving through the water will, by that very fact, expose its forward end to the operation of forces quite different from those to which the other end is exposed and so it tends to become different. Thus begins a polar differentiation which results, other things remaining equal, in radial symmetry. Now if one surface is already uppermost...
Página 113 - The cerebral mechanism is arranged just so as to drive back into the unconscious almost the whole of this past, and to admit beyond the threshold only that which can cast light on the present situation or further the action now being prepared — in short, only that which can give useful work.
Página 83 - Hysteria therefore is a disease of personal synthesis, a form of mental depression characterized by the retraction of the field of personal consciousness and a tendency to the dissociation and emancipation of the systems of ideas and functions that constitute personality.
Página 22 - physiological unity is not broken by cell-boundaries," and that "comparative embryology reminds us at every turn that the organism dominates cell-function, using for the same purpose one, several, or many cells, massing its material and directing its movements and shaping its organs, as if cells did not exist, or as if they existed only in complete subordination to its will, if I may so speak.
Página 13 - 2 The principle that the whole is of necessity something different from its parts is very old and must be accepted as obviously true but in erecting this principle into something definite and distinct, as distinct as any one of the parts, the old error is repeated of dropping into a static formulation and failing to see that what is useful in such a concept is the ability to realize that the principle of unity is dynamic : that neither the whole nor the parts have any separate existence : that they...
Página 74 - simple" protoplasm performs all the functions which in its differentiated developments fall to the share of the most various structures and the most various faculties. It sees and 'hears and smells and tastes and feels, thinks and wills and moves, it absorbs and excretes, it grows and reproduces itself, and all without any discoverable difference of structure. What then have we gained by deriving differences we can see and partly understand from hypothetical differences which are invisible and incomprehensible...
Página 16 - ... living organism and unless this is done the function under consideration will not have been fully encompassed, will not have been seen all around, not have been fully appreciated in all of its bearings, understood in its full significance. Having set forth what is meant by the organism as a whole, the fact that the whole is something different from the sum of its parts, and having indicated that the difference is due to the function of integration, it is necessary to indicate how this function...
Página 74 - ... certain purposes. In ordinary life and science, where we think backwards, and are more concerned with the past than with the future of things, the explanation by their causes, germs and potentialities is more in point. But in ultimate analysis none of these explanations are metaphysically adequate : things must be explained by their significance and purpose instead of by their " causes," by their ideals instead of by their germs, by their, actualities instead of by their potentialities. And these...
Página 73 - ... and moral. Again, all bodies gravitate, but the activities of living, to say nothing of rational, bodies cannot be explained by the action of gravitation alone. So chemical affinities are presupposed in biological actions, but yet life is something more than and beyond chemical affinity. Thus it is the same inherent flaw of the method which is displayed, not only in the palpable inadequacy of explaining biological facts by chemical or mechanical facts, but also in that of explaining the rational...
