 A conception of integrity as a virtue—either developed along the lines described above or along different lines—is compatible with the existence of constraints on the content of the norms the person of integrity is committed to. Profound moral failure may be an independent defeater of integrity, just as hypocrisy, fanaticism and the like are defeaters of integrity. One might judge as internal to such a conception of the virtue the idea that integrity is incompatible with major failures of moral imagination or moral courage, or with the maintenance of wholly unreasonable moral principles or opinions. On such a view, the Nazi could not, all things considered, be a regarded as person of integrity. The Nazi may be self-deceiver and a liar (which is highly probable), but even if he is not, his principles and his actions are not rationally defensible under any coherent moral view. And this latter fact may by itself justify the judgment that the Nazi lacks the virtue of integrity.
