The paper suggests a critique of scientism by revealing the existential genesis of knowledge-constitutive interests in scientific research. This scenario of overcoming scientism is spelled out in terms of the doctrine of cognitive existentialism. On the doctrine?s central claim, a knowledge-constitutive interest is not fixed and determined by a strongly situated epistemic position that is distinguished by invariant norms of theorizing, methodological devices, cognitive aims, goals, and values. In reflecting upon its situated transcendence, scientific research has a potentiality for discarding (...) that form of objectivist realism which is pre-supposed by the ideology of scientism. The paper develops arguments against the essentialist picture of scientific research shared by philosophers as different as Heidegger and Habermas. (shrink)
