Kant's conception of conscience has been relatively neglected by Kant scholars and the secondary literature offers no explanation of whether (and if so, how) his treatments of conscience fit together. To achieve a fuller understanding of Kant's general position on conscience, I question the widespread assumption that conscience is a feeling and account for the nature of conscience and its multiple functions. On my reading, conscience is ‘the internal judge’ whose verdict triggers certain emotional reactions. Through the moral self-evaluative activities (...) of this inner judge, we come to know our character better. In the judgements of conscience, we take account of various psychological conditions while judging both whether these conditions stand in the way of our establishing moral maxims and whether we hold ourselves accountable for our actions. By arousing certain feelings, these judgments also move us to moral action. (shrink)
