A philosopher of science responds to a meme shared by philosopher Philip Goff that suggests metaphysics is the 'real hero' behind scientific progress, while science merely operates within metaphysical frameworks provided by philosophers. The author argues this view is 'grotesquely and demonstrably false', and that metaphysics has more often led scientists away from the truth than towards it. The author contends that naturalistic materialism should be seen as a successful research program, not a metaphysical thesis, and that philosophers who think they can derive deep insights about reality from armchair reflection are 'revealing nothing more than features of their own, idiosyncratic minds'.

Why it matters

This debate over the relationship between science and metaphysics goes to the heart of how we understand the nature of reality and the respective roles of empirical investigation and a priori reasoning. The author's critique challenges the view that philosophy can provide a conceptual framework for science, arguing instead that philosophy should be an aid to the scientific enterprise by integrating the pictures provided by the sciences.

The author argues that naturalistic materialism should be seen as a successful research program, not a metaphysical thesis, and that philosophers should focus on integrating the pictures provided by the sciences rather than deriving insights about reality from armchair reflection.
