 At this point we can see why you’re not supposed to be able to opt for slackerdom. There are things we have to get done, in something like the way that the pod creatures have to fool Aunt Millie into thinking they’re her husband Melvin; acting is our ‘plight, the simple inexorable fact of the human condition’ (Korsgaard 2009, sec. 1.1.1). And that means producing actions, not mere acts; you act because there are things you have to get done, and so when you act, you normally have an end in view; to act with an end in view is to perform an action. Acting is constituting yourself as an agent out of your desires and other psychological elements, in much the way that the pod creatures constitute themselves as a group agent. The necessity of agency is not metaphysical but practical. (This amounts to a reply to the objection that the argument for the ineluctability of action involved a sleight of hand: that a series of interlocking definitions, purporting to show that you have no alternative to acting because nothing will count as an alternative to action, could not amount to a reason not to live like a slacker. The objection is misconstruing Korsgaard’s argument as turning on definitional rather than practical necessities.)
