ABSTRACT
Joseph Rouse attempts to clarify issues of normativity from the view of metaphysical naturalism, while promoting some kind of conciliation between naturalism and normativity from the meta- philosophical one. Philosophy of science is supposed to face with problem of normativity when naturalism has become a basic position. The problem of normativity could be characterized as incompatible relationships between the descriptive and the normative. Rouse’s conception of practice integrating nature and normativity has already made a reconstruction of the notion of scientific practice, as well as a reconstruction of the relationship between nature and normativity. Rouse’s notion of the normativity of scientific practice involves two basic presuppositions: philosophical naturalism and a practical conception of science. Philosophical naturalism insists on explaining normativity from natural causality. Causality and laws of nature are foundations for understanding the notion of normativity in a scientific way.
