It deals with particular events, not universal laws. However, it explains these events in part through the application of praxeological laws.
Historical explanations are by no means limited to the application of praxeology.
Also involved is the use of common sense psychology, which Mises, borrowing a term from George Santayana, calls thymology. In historical explanations, the use of ideal types is crucial. Here the historian imagines how someone would act if he were governed by specific motives, using the tools of praxeology and common-sense psychology to do this. Mises is firmly committed to methodological individualism. He opposes attempts to reify abstractions, e.g., as found in Marxist and Hegelian philosophies of history.
