a or a' ought to carry out a for moral reasons even if a is irrational for her (i.e. does not correspond to her goals). The person-relativity of action rationality seems to be responsible for this difference. An action is rational in relation to the wishes of that person. One might conclude: There are two normative theories, one of which determines what is moral, the other what is rational. Both contain specific prescriptions. One should be both — moral and rational — as far as this is possible; in case of conflict the two types of norms must be weighed against one another. The pure universalist will give precedence to morality in case of conflict; the radical particularist will favour rationality. My thesis instead is: There can be only one normative theory; thus this conflict between two normative criteria or theories is merely imaginary. To illustrate this I will fall back on an odd story which may seem familiar to some of you:" /> Rationality and morality - Nida-Rümelin Julian | sdvig press
