Religion and Experimentalism

Dewey advocates an extension of the Experimentalism that governs the Natural Sciences, to the Human Sciences.  Such extension would entail applying the trial-and-error method that establishes Truth in the former cases, to the determination of Value in the latter, i. e. experimenting with Pleasure, in the Moral Sciences, with different Economic and Political systems in the Social Sciences, etc.  However, the application that he foresees to Religion is less focused, i. e. he does not recommend, analogously, trying out different doctrines, but merely urges less supernatural dogma, and, thus, greater flexibility, in the pursuit of natural ends.  Now, Dewey also asserts that an artist is "born an experimenter", but without considering the implications of that formulation for the Experimentalist revolution that he proposes.  For example, perhaps the quintessential experimental artist is the jazz musician, for whom improvisation is not a means to some ulterior discovery, but is performed for its own sake.  On that basis, an Experimentalist revamping of Religion would begin with a concept of a deity as an improvising creator.
