Throughout this long development, from 600 B.C. to the present day, philosophers have been divided into those who wished to tighten social bonds and those who wished to relax them. With this difference others have been associated. The disciplinarians have advocated some system of dogma, either old or new, and have therefore been compelled to be in a greater or less degree, hostile to science, since their dogmas could not be proved empirically. They have almost invariably taught that happiness is not the good, but that "nobility" or "heroism" is to be preferred. They have had a sympathy with the irrational parts of human nature, since they have felt reason to be inimical to social cohesion. The libertarians, on the other hand, with the exception of the extreme anarchists [Robespierre!], have tended to be scientific, utilitarian, rationalistic, hostile to violent passion, and enemies of all the more profound forms of religion. This conflict existed in Greece before the rise of what we recognize as philosophy, and is already quite explicit in the earliest Greek thought. In changing forms, it has persisted down to the present day, and no doubt will persist for many ages to come.
