Causal Models and the Asymmetry of State Preparation

According to a widespread view, which can be traced back to Russell’s famous attack on the notion of cause, causal notions have no legitimate role to play in mature physical theorizing. This view has proponents even among those who believe that causal notions have an important place in our folk conception of the world. In this paper I critically examine Bas van Fraassen’s articulation of this view in a debate with Nancy Cartwright. I argue that there is an asymmetry of state preparation characterizing our experimental interactions with physical systems that can provide a justification for asymmetric causal assumptions even within the context of a physics with time-reversal invariant dynamical equations.
