 There is a tradition that stretches back at least as far as Russell (1913) that denies that there is any place for causal notions in the fundamental sciences, including physics: the notion serves no purpose, and simply does not appear, in the fundamental sciences. The argument goes that, since at least the nineteenth century, the laws that govern physical behavior in fundamental sciences such as physics are almost always differential equations. Such equations are notable for specifying, given some initial conditions, exact properties of systems for all time. And thus if everything is specified for all time, there is no place left for causality. Thus Russell advocates that “causality” should be eliminated from the philosophers lexicon, because it is certainly not a part of the scientific lexicon.
