The paper criticizes two prominent accounts which purport to explain normativity by appealing to some relation that one bears to oneself. Michael Bratman argues that one has reason to be formally coherent because otherwise one would fail to govern oneself. And David Velleman argues that one has reason to be formally coherent because otherwise one would be less intelligible to oneself. Both Bratman and Velleman argue in quite different ways that rational coherence is normative because it is necessary for the (...) instantiation or promotion of the independently normative self-relation they invoke. But the paper presents a similar scenario which arguably exposes a failure of extensional adequacy common to both accounts: one can instantiate the self-relation in question without being formally coherent. A brief diagnosis is offered for why two such different accounts turn out to be vulnerable to a similar counterexample, suggesting that other accounts which appeal to self-relations in a broadly similar way might also suffer from the problem identified here.

ABSTRACTThis essay argues that in spite of the powerful arguments by Kolodny and Broome there is a reason to be rational. The suggested reason to be rational is that if an agent complies with ratio...

Science-based methods for assessing the practical rationality of a proposed public policy typically represent assumed future outcomes of policies and values attributed to these outcomes in an idealized, that is, intentionally distorted way and abstracted from aspects that are deemed irrelevant. Different types of methods do so in different ways. As a consequence, they instantiate the properties that result from abstraction and idealization such as conceptual simplicity versus complexity, or comprehensiveness versus selectivity of the values under consideration to different degrees. (...) I hold that none of these methods is best in general. Instead, I opt for the valuation method that is useful for the policy issue in question both in terms of its relevance and in terms of its practicability. Relevance requires that the method can represent and account for what is at stake in the policy issue. Practicability refers to aspects such as easy versus difficult handling of the method. To argue for the claim, I evaluate three types of valuation methods: cost–benefit analysis that rests on unidimensional measurement and ranking, multi-criteria decision analysis that applies multi-dimensional measurement but unidimensional ranking, and non-aggregate indicator systems that operate with multi-dimensional measurement and sometimes also multi-dimensional ranking. Second-order justification indicating whether and how the valuation method chosen is capable of accounting for the substantive value considerations that constitute the real-world policy issue in question renders the conditions on which the results of a proposed policy evaluation rest transparent.
