 In 1918, Meinong published his last major work — an attempt at proving the law of universal causation, i.e. the principle that assures the unexceptional causal determination of all occurrences (states, events). He provides two arguments in favor of this principle. First, he argues, following Hobbes and Brentano, that uncaused events turn out to be infinitely improbable. Second, Meinong uses an a priori proof of his own which claims that exceptionless determinacy is necessary as no occurrence can be without a state of affairs that Meinong calls its “implicans” (1918: 45–66; cf. Hartmann 1920). Meinong not only supports determinism, he also defends compatibilism because determinism, and not indeterminism, allows us to ascribe responsibility (for being guilty, or meritorious etc.) to persons (1894, §68; 1918: 92: “Freedom is not indeterminacy, and determinacy is not compulsion or coercion”).
