David Lewis famously argued that the time traveller ‘can’ murder her grandfather, even though she never will: it is compossible with a particular set of facts including her motive, opportunity and skill (1976: 150). I argue that while ordinary agents ‘can’ under Lewis’s conception, philosophers cannot – the latter will not only fail to fulfill their homicidal intentions but also fail to form them in the first place.
