Instrumental rationality
（重定向自Instrumental reason）
Instrumental rationality (or instrumental reason) is a mode of thought and action that identifies problems and works directly towards their solution.
Instrumental rationality is often studied as a social phenomenon by sociology, social philosophy and critical theory. Its proponents appear to work largely without reference to the school Instrumentalism, with which it is so closely associated linguistically. Perhaps its most famous critic is philosopher Martin Heidegger, who argued that the greatest danger facing modern humans was their own instrumental relationship to the world.
