  Philosophers have heavily criticized Lewis’s reliance upon salience, arguing that the notion of salience is obscure, or that there is often no salient option among candidate conventions, or that precedence does not confer salience, or that Lewis fails to integrate salience into the formal game-theoretic framework that otherwise shapes his discussion. Margaret Gilbert (1989) argues that salience cannot provide a reason for action: merely observing that some possible convention is salient tells us nothing, because we cannot assume that others will abide by the most salient convention. In a similar vein, Brian Skyrms (1996) asks how it comes to be common knowledge that others will choose the salient equilibrium over the alternatives.
