Henry Shevlin(@dioscuri):Universalisability usually comes up in ethics (“what if everyone did this?”), but it works pragmatically within a single life too. Before you text at the wheel or ride without a helmet, ask if you could rationally endorse such a policy for all similar moments. Almost always no!
