Página 214 - We understand union in the sense of local connection ; here is a union where local connection is irrelevant, unsuitable, contradictory, for we cannot think of mind without putting ourselves out of the world of place. When, as in pure feeling — pleasure or pain — we change to the subject attitude from the object attitude, we have undergone a change not to be expressed by place ; the fact is not properly described by the transition from the external to the internal, for that is still a change in...
Página 194 - There are two opposite errors on this subject : one is the old error of regarding vital force as something innate, underived, having no relation to the other forces of Nature ; the other is the new error of regarding the forces of the living body as nothing but ordinary physical and chemical forces, and therefore insisting that the use of the term vital force is absurd and injurious to science. The old error is still prevalent in the popular mind, and still haunts the minds of many physiologists...
Página 209 - In. the second place, we have every reason for believing that there is, in company with all our mental processes, an unbroken material succession. From the ingress of a sensation, to the outgoing responses in action, the mental succession is not for an instant dissevered from a physical succession.
Página 215 - Asserting the union in the strongest manner, we must yet deprive it of the almost "invincible association of union in place. An extended organism is the condition of our passing into a state where there is no extension. A human being is an extended and material thing, attached to which is the power of becoming alive to feeling and thought, the extreme remove from all that is material ; a condition of trance wherein, while it lasts, the material drops out of view — so much so, that we have not the...
Página 60 - Now, heterogeneity is an essential element of this latter force — there must be a difference of some kind before it can exhibit itself — and under these circumstances its exhibitions are frequently characterized by very extraordinary and interesting phenomena. We allude to that peculiar exhibition arising out of the forces of heterogenous bodies which we call electricity, and, before proceeding further, it may not be out of place to give a short sketch of the mode of action of this very mysterious,...

Página 215 - ... without the extended consciousness the unextended would not arise. Without certain peculiar modes of the extended — what we call a cerebral organization, and so on — we could not have those times of trance, our pleasures, our pains, and our ideas, which at present we undergo fitfully and alternately with our extended consciousness.
Página 151 - If we could view the universe as a candle not lit, then it is perhaps conceivable to regard it as having been always in existence ; but if we regard it rather as a candle that has been lit, we become absolutely certain that it cannot have been burning from eternity, and that a time will come when it will cease to burn. We are led to look to a beginning in which the particles of matter were in a diffuse chaotic state, but endowed with the power of gravitation, and we are led to look to an end in which...
Página 204 - The mechanical equivalent of heat, the 772 foot pounds of Joule, expresses the rate of exchange between mechanical momentum and heat ; the equivalent or exchange of heat and chemical force is given (through the researches of Andrews and others) in the figures expressing the heat of combinations ; for example, one pound of carbon burnt evolves heat enough to raise 8,080 pounds of water one deg.
