Стр. 450 - If such do occur, can we doubt (remembering that many more individuals are born than can possibly survive) that individuals having any advantage, however slight, over others, would have the best chance of surviving and of procreating their kind?
Стр. 450 - Several writers have misapprehended or objected to the term Natural Selection. Some have even imagined that natural selection induces variability, whereas it implies only the preservation of such variations as arise and are beneficial to the being under its conditions of life.
Стр. 394 - What limit can be put to this power, acting during long ages and rigidly scrutinising the whole constitution, structure, and habits of each creature, — favouring the good and rejecting the bad? I can see no limit to this power, in slowly and beautifully adapting each form to the most complex relations of life.
Стр. 443 - And as Natural Selection works solely by and for the good of each being, all corporeal and mental endowments will tend to progress towards perfection.
Стр. 258 - ... would have broken the glass ; had he been close to a drum-head he would have shaken the drum. We could thus transmit a push through a row of a hundred boys, each particular boy, however, only swaying to and fro. Thus, also, we send sound through the air and shake the drum of a distant ear, while each particular particle of the air concerned in the transmission of the pulse makes only a small oscillation.
Стр. 445 - Natural selection acts only by the preservation and accumulation of small inherited modifications, each profitable to the preserved being...
Стр. 29 - That gravity should be innate, inherent and essential to matter so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another is to me so great an absurdity that I believe no man who has in philosophical matters a competent faculty of thinking can ever fall into...
Стр. 508 - If it could be proved that any part of the structure of any one species had been formed for the exclusive good of another species, it would annihilate my theory, for such could not have been produced through natural selection.
Стр. 394 - Let this process go on for millions of years; and during each year on millions of individuals of many kinds; and may we not believe that a living optical instrument might thus be formed as superior to one of glass, as the works of the Creator are to those of man ? Modes of Transition.
Стр. 254 - The same air is competent to accept and transmit the vibrations of a thousand instruments at the same time. When we try to visualise the motion of that air — to present to the eye of the mind the battling of the pulses direct and reverberated — the imagination retires baffled from the attempt.
