 O’Neill (2000) situates the Kantian account of reason against three alternatives, which she labels the instrumental, the communitarian, and the perfectionist. The first remains very widespread: with Hume, it regards instrumental reasoning as fundamental (cf.  practical reason, §4;  reasons for action: internal vs. external).   The second sees reason as embedded within complex traditions: rationality is what a given tradition or community takes it to consist in (cf. MacIntyre 1988;  communitarianism).  A third option, akin to the forms of rationalism that Kant opposed, is to see reason as an individual capacity to discern or intuit normative truths (cf.  moral non-naturalism, §3).  Arguably, all three accounts fail in providing reasoned justification to some audiences. The instrumental reasoner is accountable to no-one—in fact, to nothing apart from whatever desires or ends he happens to have. Someone who takes her particular tradition to define what beliefs and practices count as reasonable can have little to say to those who stand outside it. And the person who believes he can intuit what is good or true will be mute—or worse—in the face of those with different  intuitions.[27]
