Since there is so much we can do together – good and bad – we are subject to numerous normative requirements to perform certain actions and to abstain from others. In what follows I will argue that some intuitively feasible requirements, especially those that are collective, are not in fact feasible. I thereby aim to offer a revised account of what counts as a feasible action. In particular, I argue that we can best preserve the spirit of what is known as the conditional account of feasibility if we move to what I call the constrained account.
