What Wikipedia says about pragmatism.
The primacy of practice (from Wikipedia)
The pragmatist proceeds from the basic premise that the human capability of theorizing is integral to intelligent practice. Theory and practice are not separate spheres; rather, theories and distinctions are tools or maps for finding our way in the world. As John Dewey put it, there is no question of theory versus practice but rather of intelligent practice versus uninformed, stupid practice and noted in a conversation with William Pepperell Montague that "[h]is effort had not been to practicalize intelligence but to intellectualize practice". (Quoted in Eldridge 1998, p. 5) Theory is an abstraction from direct experience and ultimately must return to inform experience in turn. Thus an organism navigating his or her environment is the grounds for pragmatist inquiry.
