The following article aims to shed a light on the role of instrumentalism in John Dewey's epistemology as well as philosophy of science. Its basic conclusion is that Dewey can be considered an unorthodox realist, following the terminology by Godfrey-Smith , and that his instrumentalist position can be interpreted as a problem-solving approach (Laudan ) to science. The connection to Logical Empiricism lies in Hans Reichenbach 's analysis of Dewyan instrumentalism.
