 Some authors have challenged premise 5 of the time-asymmetry challenge, according to which only those features that can be grounded in physical laws can play a proper role in physics. In effect, this premise implies that the proper content of physics is restricted to physical laws, thereby denying that initial, final, or boundary conditions are an integral part of the content of physics. One motivation for this restriction might be the thought that initial or final conditions are contingent “one-off” states, and hence should not count as part of the content of physics, which consists of general claims about the physical world: that a billiard ball was at rest on a specific spot on a billiard table when it was struck by a second ball is not part of physics but the laws of elastic collision are. But this line of thought ignores that initial conditions can also have more general features that are shared across a wide class of conditions. In fact, many physical situations are characterized by an asymmetry between prevailing initial and final conditions, according to which initial conditions are random while final conditions are not. And this asymmetry arguably is closely related to a causal asymmetry (Arntzenius 1992; Maudlin 2007).
