Causal Reasoning in Physics
Mathias Frisch, University of Maryland
Many philosophers of physics maintain appear to believe that there is no room for substantive causal notions in our more mature theories of physics. In this paper I first critically examine several anti-causal arguments and then discuss two examples of causal reasoning in physics. The first example is a well-established part of mature physics: the derivations of both classical and quantum dispersion relations in scattering phenomena. The second example concerns a theory that currently is rather more speculative: the causal-set approach to quantum gravity.
