The article explores the connection between science and metaphysics, questioning if metaphysics can be based on science. It argues that scientific theories can provide some insight into the world, but the exact nature of reality is not fully determined by them. The author suggests that constructing a metaphysical system involves interpreting scientific theories to place constraints on possible metaphysical interpretations. Some theories are easier to interpret than others. An example from science and theology is used to illustrate how this process works.
