The Maskarins were thus fatalists or determinists. Others, labeled compatibilists (or "soft determinists"), believe that the two ideas can be reconciled coherently. Important indeterministic determinists mentioned are Christoph von Sigwart and Wilhelm Wundt. The materialist philosophers Democritus and his mentor Leucippus are considered to be the first determinists. Causal determinists believe that there is nothing uncaused or self-caused. If this argument holds, hard determinists are restricted to moral nihilism. Two foundational media determinists are the Canadian scholars Harold Innis and Marshall McLuhan. Prominent environmental determinists included Carl Ritter, Ellen Churchill Semple, and Ellsworth Huntington. He and other determinists, like Baruch Spinoza, eschewed the concept of moral guilt and responsibility. This feature, however, is tenable only as far as hard determinists discard responsibility. This is certainly the case, at least, for materialistic determinists. This work was misinterpreted by many of his students, creating a number of environmental determinists. Hard determinists would view technology as developing independent from social concerns. Moral determinists would most likely adopt a similar point of view.
