It is commonly taken for granted that questions of feasibility are highly relevant to our normative thinking – and perhaps especially our normative thinking about politics. But what exactly does this preoccupation with feasibility amount to, and in what forms if any is it warranted? This article aims to provide a critical introduction to, and clearer characterization of, the feasibility issue. I begin by discussing the question of how feasibility is to be understood. I then turn to the question of (...) feasibility’s role, suggesting that there are two quite different kinds of role questions that may be at play, though they are often run together: a question about feasibility’s normative significance; and a question about its proper use in informing our normative thinking. Finally, I consider how the feasibility issue differs from certain other related issues: the demandingness issue; the issue of whether “ought” implies “can;” and the “ideal versus non-ideal theory” issue.

This article takes a new idea, ‘normative behaviourism’, and applies it to global political theory, in order to address at least one of the problems we might have in mind when accusing that subject of being too ‘unrealistic’. The core of this idea is that political principles can be justified, not just by patterns in our thinking, and in particular our intuitions and considered judgements, but also by patterns in our behaviour, and in particular acts of insurrection and crime. The (...) problem addressed is ‘cultural relativism’, understood here not as a meta-ethical doctrine, but as the apparent ‘fact’ that people around the world have culturally varying intuitions and judgements of a kind that lead them to affirm different political principles. This is a problem because it seems to follow (1) that global agreement on any substantial set of political principles is impossible, and (2) that any political theory in denial of this ‘fact’ would be, for that reason, deeply unrealistic. The solution argued for here is that, if domestic political principles (i.e. principles intended to regulate a single state) could be justified by normative behaviourism, and in reference to culturally invariant behaviour, then an international system supportive of such principles is justifiable by extension.
