Abstract

Much of the literature on the question “Is a human essentially distinct from every possible machine?” proceeds on the assumption that we know what a man essentially is, namely a living body with such attributes as consciousness, freedom, feeling and linguistic competence. Is a man essentially that? The paper contrasts that picture of man with Kierkegaard’s account of man as essentially self. Hard limits of machine subjectivity begin to appear in the failure of certain everyday concepts involving ‘self’ to engage at all with the concept ‘machine’.
