Page 526 - If a course of conduct is habitually and deliberately pursued by vast multitudes of otherwise well-conducted people, forming probably a majority of the whole educated class of the nation," as Sidney Webb rightly puts it, "we must assume that it does not conflict with their actual code of morality.

There scarcely exists among scientific men the recognition of common interest and the spirit of cooperation which would help to give science the place it should have in the community.
