Abstract

On a ‘comparative’ conception of practical reasons, reasons are like ‘weights’ that can make an action more or less rational. Bernard Gert adopts instead a ‘toggle’ conception of practical reasons: something counts as a reason just in case it alone can make some or other otherwise irrational action rational. I suggest that Gert’s conception suffers from various defects, and that his motivation for adopting this conception – his central claim that actions can be rational without there being reasons for them – does not require adoption of the toggle conception. The more intuitive comparative conception of reasons for action can accommodate the insight.
