الصفحة 291 - is a definite combination of heterogeneous changes, both simultaneous and successive, in correspondence with external coexistences and sequences.
الصفحة 213 - The sense of space, and in the end the sense of time, were both powerfully affected. Buildings, landscapes, &c. were exhibited in proportions so vast as the bodily eye is not fitted to receive. Space swelled, and was amplified to an extent of unutterable infinity.
الصفحة 164 - A relation between feelings is, on the contrary, characterized by occupying no appreciable part of consciousness. Take away the terms it unites, and it disappears along with them ; having no independent place — no individuality of its own. It is true that, under an ultimate analysis, what we call a relation proves to be itself a kind of feeling — the momentary feeling accompanying the transition from one conspicuous feeling to an adjacent conspicuous feeling.
الصفحة 449 - Being the constant and infinitely repeated elements of thought, they must become the automatic elements of thought — the elements of thought which it is impossible to get rid of — the 'forms of intuition.
الصفحة 289 - If the doctrine of Evolution is true, the inevitable implication is that Mind can be understood only by observing how Mind is evolved. If creatures of the most elevated kinds have reached those highly integrated, very definite, and extremely heterogeneous organizations they possess, through modifications upon modifications accumulated during an immeasurable past — if the developed nervous * This Chapter stands in place of five chapters which, in the original edition of this work, prepared the way...
الصفحة 160 - Eventually he is obliged to admit that his ideas of Matter and Motion, merely symbolic of unknowable realities, are complex states of consciousness built out of units of feeling. But if, after admitting this, he persists in asking whether units of feeling are of the same nature as the units of force distinguished as external, or whether the units of force distinguished as external are of the same nature as units of feeling; then the reply, still substantially the same, is that we may go farther towards...

The crowbar is but one more lever attached to the series of levers forming the arm and hand. And the relationship which is so obvious in these first steps, holds throughout.
الصفحة 98 - Now, however, we turn to a totally-distinct aspect of our subject. There lies before us a class of facts absolutely without any perceptible or conceivable community of nature with the facts that have occupied us. The truths here to be set down are truths of which the very elements are unknown to physical science. Objective observation and analysis fail us ; and subjective observation and analysis must supplement them. In other words, we have to treat of nervous phenomena as phenomena of consciousness....
الصفحة 379 - ... if the anterior segment of the thorax, with its attached members, be removed, the posterior part of the body will still remain balanced upon the four legs which belong to it, resisting any attempts to overthrow it, recovering its position when disturbed, and performing the same agitated movements of the wings and elytra as when the unmutilated insect is irritated ; on the other hand, the detached portion of the thorax, which contains a ganglion, will, when separated from the head, set in motion...
الصفحة 385 - That an effectual adjustment may be made, they must be all brought into relation with one another. But this implies some centre of communication common to them all, through which they severally pass, and as they cannot pass through it simultaneously, they must pass through it in succession. So that as the external phenomena responded to become greater in number and more complicated in kind, the variety and rapidity of the changes to which this common centre of communication is subject must increase...
