 In his numerous academic works, Sturm forcefully defends the use of the experimental method in natural philosophy. He advocates an inclusive and open-minded examination of old and new philosophical theories in order to find the best explanations for observed phenomena. In metaphysics, Sturm is one of the most outspoken supporters of occasionalism, the theory according to which finite beings lack genuine causal powers and work only as occasions for God’s causal intervention in nature. While occasionalism was developed before Sturm by a number of other authors, Sturm gives his own original twist to it by making it the foundation of his system of natural philosophy.
