 Durkheim's sociology was a realist and inductive science whereby theory would trail observations, while the scientific method proceeded from social facts to hypotheses to general laws—their priority being their causal accord—to be identified indeed inductively.World War erupted in 1914 and closed in 1919 with a treaty upon reparations that British economist John Maynard Keynes immediately, vehemently predicted would crumble German society by hyperinflation—a prediction fulfilled by 1923.Via the 29 May 1919 solar eclipse, Einstein's gravitational theory, confirmed in its astonishing prediction, apparently overthrew Newton's, a revolution bitterly resisted by many scientists but completed nearing 1930.
