الصفحة 183 - The mores come down to us from the past. Each individual is born into them as he is born into the atmosphere, and he does not reflect on them, or criticise them any more than a baby analyzes the atmosphere before he begins to breathe it.
الصفحة 117 - The great difficulty which history records is not that of the first step, but that of the second step. What is most evident is, not the difficulty of getting a fixed law, but getting out of a fixed law ; not of cementing...
الصفحة 118 - ... is among the first by which Providence guides and governs the world, there is a tendency in descendants to be like their progenitors, and yet a tendency also in descendants to differ from their progenitors. The work of Nature in making generations is a patchwork — part resemblance, part contrast. In certain respects each born generation is not like the last born ; and in certain other respects it is like the last. But the peculiarity of arrested civilization is to kill out varieties at birth...
الصفحة 189 - Of course, the proposition is not necessarily communicated in formal language, it may be implied by a mere gesture or interjection. The suggestibility of any subject is not of the same degree at all times ; it varies not only according to the topic and according to the source from which the proposition is communicated, but also with the condition of the subject's brain from hour to hour. The least degree of suggestibility...
الصفحة 113 - A word is a vehicle, a boat floating down from the past, laden with the thought of men we never saw; and in coming to understand it we enter not only into the minds of our contemporaries, but into the general mind of humanity continuous through time.
الصفحة 5 - I have attempted to explain heredity by supposing that in each ontogeny, a part of the specific germ-plasm contained in the parent egg-cell is not used up in the construction of the body of the offspring, but is reserved unchanged for the formation of the germ-cells of the following generation.
الصفحة 196 - There is an undoubted tendency in the advance of civilization to eliminate traditional elements, and to gain a clearer and clearer insight into the hypothetical basis of our reasoning. It is therefore not surprising that, with the advance of civilization, reasoning becomes more and more logical, not because each individual carries out his thought in a more logical manner, but because the traditional material which is handed down to each individual has been thought out and worked out more thoroughly...
الصفحة 122 - Man has been so noisy about the way he has "conquered Nature," and Nature has been so silent in her persistent influence over man, that the geographic factor in the equation of human development has been overlooked.
الصفحة 5 - Regarded from this point of view, life is like a current passing from germ to germ through the medium of a developed organism. It is as if the organism itself were only an excrescence, a bud caused to sprout by the former germ endeavoring to continue itself in a new germ.
الصفحة 129 - The head form, which has always been considered as one of the most stable and permanent characteristics of human races, undergoes far-reaching changes due to the transfer of the races of Europe to American soil. The east European Hebrew, who has a very round head, becomes more long-headed; the south Italian, who in Italy has an exceedingly long head, becomes more short-headed ; so that both approach, a uniform type in this country, so far as the roundness of the head is concerned.
