This article discusses the self-respect argument for basic liberties, which is that self-respect is an important good, best supported by basic liberties, and that this yields a reason for the traditional liberty principle. I concentrate on versions of it that contend that self-respect is best supported by basic liberties for reasons related to the recognition that such liberties convey. I first discuss the two standard approaches loosely associated with John Rawls and Axel Honneth. Here self-respect pertains to traits and conduct (...) (Rawls) or to one’s personhood (Honneth). It is argued that these approaches fail to show why self-respect is better supported by the liberty principle than certain alternatives worth taking seriously – unless (in the case of personhood self-respect) self-respect is construed in such a narrow way that it is not a condition for autonomy or welfare in any plausible sense. I then identify a self-attitude that I call “a sense of competence”, which at least shows that the liberty principle is more important to autonomy than what we might otherwise have reasons to believe.
