Note 3 — TWENTIETH CENTURY SOCIALISM

Engels and others have described Marxian or Economic Socialism as scientific, on the ground that Marx was the first to reduce Socialism to a science. But the word science has become so inseparably connected in our minds with chemistry, physics, biology, zoology, and geology, etc., that it seems wiser to define Marxian Socialism as economic and to keep the word scientific for that view of Socialism which is built on the sciences proper and principally on biology.
