Ethics: Origin and Development By Peter Kropotkin CHAPTER III THE MORAL PRINCIPLE IN NATURE THE work of Darwin was not limited to biology only. Already in 1837, when he had just written a rough outline of his theory of the origin of species, he entered in his notebook this significant remark: "My theory will lead to a new philosophy." And so it did in reality. By introducing the idea of evolution into the study of organic life he opened a new era in philosophy,1 and his later sketch of the development of the moral sense, turned a new page in ethics. In this sketch Darwin presented in a new light the true origin of the moral sense, and placed the whole subject on such a firm scientific basis, that although his leading ideas may be considered as a further development of those of Shaftesbury and Hutcheson, he must be, nevertheless, credited with opening a new path for science in the direction faintly indi...
Since Anthropology--the history of man's physiological development and of his religious, political ideals, and economic institutions--came to be studied exactly as all other natural sciences are studied, it was found possible, not only to shed a new light upon this history, but to divest it for ever of the metaphysics which had hindered this study in exactly the same way as the Biblical teachings had hindered the study of Geology. It would seem, therefore, that when the construction of a synthetic philosophy was undertaken by Herbert Spencer, he should have been able, armed as he was with all the latest conquests of science, to build it without falling into the errors made by Comte in his "Positive Politics." And yet Spencer's synthetic philosophy, though it undoubtedly represents an enormous step in advance (complete as it is without religion and religious rites), still contains in its sociological part mistakes as gross as are found in the for...
