Стр. 193 - There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.
Стр. 193 - To my mind it accords better with what we know of the laws impressed on matter by the Creator, that the production and extinction of the past and present inhabitants of the world should have been due to secondary causes, like those determining the birth and death of the individual.
Стр. 174 - On my return home, it occurred to me, in 1837, that something might perhaps be made out on this question by patiently accumulating and reflecting on all sorts of facts which could possibly have any bearing on it. After five years' work I allowed myself to speculate on the subject, and drew up some short notes...
Стр. 174 - After five years' work I allowed myself to speculate on the subject, and drew up some short notes ; these I enlarged in 1844 into a sketch of the conclusions, which then seemed to me probable : from that period to the present day I have steadily pursued the same object. I hope that I may be excused for entering on these personal details, as I give them to show that I have not been hasty in coming to a decision.
Стр. 193 - When I view all beings not as special creations, but as the lineal descendants of some few beings which lived long before the first bed of the Cambrian system was deposited, they seem to me to become ennobled.
Стр. 178 - A struggle for existence inevitably follows from the high rate at which all organic beings tend to increase. Every being, which during its natural lifetime produces several eggs or seeds, must suffer destruction during some period of its life, and during some season or occasional year, otherwise, on the principle of geometrical increase, its numbers would quickly become so inordinately great that no country could support the product.
Стр. 26 - No life, my honest scholar, no life so happy and so pleasant as the life of a well-governed angler; for when the lawyer is swallowed up with business, and the statesman is preventing or contriving plots, then we sit on cowslip banks, hear the birds sing, and possess ourselves in as much quietness as these silent silver streams, which we now see glide so quietly by us.
Стр. 12 - By and by the water began to change. It grew denser, and no longer flowed rapidly along; and twice a day it used to turn about and flow the other way. Then the shores disappeared, and the water began to have a different and peculiar flavor — a flavor which seemed to the salmon much richer and more inspiring than the glacier water of their native Cowlitz.
Стр. 173 - ... that mystery of mysteries, as it has been called by one of our greatest philosophers.
Стр. 18 - ... chin, each had to turn aside to let the other pass. His beautiful teeth grew longer and longer, and projected from his mouth, giving him a savage and wolfish appearance, quite at variance with his real disposition. For all the desires and ambitions of his nature had become centred into one.
