Síða 396 - History warns us, however, that it is the customary fate of new truths to begin as heresies and to end as superstitions...
Síða 373 - Our sensations, our pleasures, our pains, and the relations of these make up the sum total of the elements of positive, unquestionable knowledge. We call a large section of these sensations and their relations matter and motion ; the rest we term mind and thinking ; and experience shows that there is a certain constant order of succession between some of the former and some of the latter.
Síða 361 - It is genius, and not the want of it, that adulterates philosophy, and fills it with error and false theory. A creative imagination disdains the mean offices of digging for a foundation, of removing rubbish, and carrying materials; leaving these servile employments to the drudges in science, it plans a design, and raises a fabric.
Síða 396 - The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is co-extensive with its power of resisting extinction by its rivals.
Síða 496 - Democritus and medicine. Nevertheless, in so far as he, and those who worked before and after him, in the same spirit, ascertained, as matters of experience, that a wound, or a luxation, or a fever, presented such and such symptoms, and that the return of the patient to health was facilitated by such and such measures, they established laws of nature, and began the construction of the science of pathology. All true science begins with empiricism — though all true science is such exactly, in so...
Síða 133 - It may be true to say that there is a primitive identity of structure between the spinal or vertebral column and the skull; but it is no more true that the adult skull is a modified vertebral column than it would be to affirm that the vertebral column is modified skull.
Síða 498 - Stahl ; and, later, to the doctrine of a vital principle, that " asylum ignorantiae " of physiologists, which has so easily accounted for everything and explained nothing, down to our own times. Now the essence of modern as contrasted with ancient physiological science, appears to me to lie in its antagonism to animistic hypotheses and animistic phraseology. It offers physical explanations of vital phenomena, or frankly confesses that it has none to offer. And, so far as I know, the first person...
Síða 249 - The register of knowledge of fact is called history :. Whereof there be two sorts: one called natural history, which is the history of such facts, or effects of nature, as have no dependence on man's mill, such as are the histories of metals, plants, animals, regions, and the like. The other is civil history, which is the history of the voluntary actions of men in commonwealths.
Síða 253 - Now in an Englishman's mouth it generally means that by which we get pudding or praise, or both. I have no doubt that is one meaning of the word utility, but it by no means includes all I mean by utility. I think that knowledge of every kind is useful in proportion as it tends to give people right ideas, which are essential to the foundation of right practice, and to remove wrong ideas, which are the no less essential foundations and fertile mothers of every description of error in practice.
Síða 360 - The white medullary substance of the brain is also the immediate instrument by which ideas are presented to the mind ; or, in other words, whatever changes are made in this substance, corresponding changes are made in our ideas; and vice versa.
