Стр. 146 - In however complex a manner this feeling may have originated, as it is one of high importance to all those animals which aid and defend one another, it will have been increased through natural selection; for those communities, which included the greatest number of the most sympathetic members, would flourish best, and rear the greatest number of offspring.
Стр. 191 - Looking to the distant future, I do not think that the Rev. Mr. Zincke takes an exaggerated view when he says: "All other series of events — as that which resulted in the culture of mind in Greece, and that which resulted in the empire of Rome — only appear to have purpose and value when viewed in connection with, or rather as subsidiary to ... the great stream of Anglo-Saxon emigration to the west.
Стр. 179 - A tribe including many members who, from possessing in a high degree the spirit of patriotism, fidelity, obedience, courage, and sympathy, were always ready to aid one another, and to sacrifice themselves for the common good, would be victorious over most other tribes; and this would be natural selection.
Стр. 92 - We should, however, bear in mind that an animal possessing great size, strength, and ferocity, and which, like the gorilla, could defend itself from all enemies, would not perhaps have become social: and this would most effectually have checked the acquirement of the higher mental qualities, such as sympathy and the love of his fellows. Hence it might have been an immense advantage to man to have sprung from some comparatively weak creature.
Стр. 166 - As man advances in civilization, and small tribes are united into larger communities, the simplest reason would tell each individual that he ought to extend his social instincts and sympathies to all the members of the same nation, though personally unknown to him. This point being once reached, there is only an artificial barrier to prevent his sympathies extending to the men of all nations and races.
Стр. 164 - As the social instincts both of man and the lower animals have no doubt been developed by nearly the same steps, it would be found advisable, if found practicable, to use the same definition in both cases, and to take as the standard of morality the general good or welfare of the community rather than the general happiness.
Стр. 201 - We may thus ascend to the Lemuridae; and the interval is not very wide from these to the Simiadae. " The Simiadae then branched off into two great stems, the New World and Old World monkeys; and from the latter, at a remote period, man, the wonder and glory of the universe, proceeded.
Стр. 137 - It may be well first to premise that I do not wish to maintain that any strictly social animal, if its intellectual faculties were to become as active and as highly developed as in man, would acquire exactly the same moral sense as ours.
Стр. 100 - In the agony of death a dog has been known to caress his master, and every one has heard of the dog suffering under vivisection, who licked the hand of the operator; this man, unless the operation was fully justified by an increase of our knowledge, or unless he had a heart of stone, must have felt remorse to the last hour of his life.
Стр. 157 - Thus at last man comes to feel through acquired and perhaps inherited habit, that it is best for him to obey his more persistent instincts. The imperious word ought...
