In this paper¹ I shall attempt to argue that there are inherent conceptual limitations of the scientific method and scientific models for the study of the basic phenomena of religion. It will be necessary, first, to state what I take to be the nature of science, and then to argue how its methodology is specifically inadequate to deal with the important facts of religion. To do this I shall begin by sketching the nature of science, drawing from such diverse philosophers and scientists as William James, Ernst Cassirer, Albert Einstein, Max Planck, Ernest Nagel, Moritz Schlick, Philipp Frank, Henry Margenau, Carl Hempel, Henri Poincaré, Ernst Mach, and Stephen Toulmin, and others.
