“Socialism is directed towards a social-ethical end. Science, however, cannot create ends and, even less, instill them in human beings; science, at most, can supply the means by which to attain certain ends. But the ends themselves are conceived by personalities with lofty ethical ideals and — if these ends are not stillborn, but vital and vigorous — are adopted and carried forward by those many human beings who, half unconsciously, determine the slow evolution of society. For these reasons, we should be on our guard not to overestimate science and scientific methods when it is a question of human problems; and we should not assume that experts are the only ones who have a right to express themselves on questions affecting the organization of society.”

Context: Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing. Unless this be the essential aim of revolution, violent social changes would have no justification. For external social alterations can be, and have been, accomplished by the normal processes of evolution. Revolution, on the contrary, signifies not mere external change, but internal, basic, fundamental change. That internal change of concepts and ideas, permeating ever-larger social strata, finally culminates in the violent upheaval known as revolution.
