According to the Ought-Implies-Can principle (OIC), an agent ought to perform a certain action only if the agent can perform that action. Proponents of OIC interpret this supposed implication in several ways. Some argue that the implication in question is a logical one, namely, entailment. Some think that the relation between ‘ought’ and ‘can’ is a relation of presupposition. Still others argue that ‘ought’ conversationally implicates ‘can’. Opponents of OIC offer a variety of counterexamples in an attempt to show that (...) there are cases in which an agent ought to perform a certain action even though she cannot perform that action. Such counterexamples often involve either culpable or nonculpable inability. In cases of culpable inability, the agent renders herself unable to fulfill an obligation. For example, a student is unable to submit a paper on the due date because she procrastinated until it became too late to write a paper by the assigned deadline. In cases of non-culpable inability, the agent somehow becomes unable to fulfill an obligation, through no fault of her own. For example, an agent becomes unable to pay back a loan to a bank because she was robbed on her way to the bank. This paper attempts to offer counterexamples to OIC of a sort different from the one discussed by opponents of OIC so far. If these counterexamples are correct, then they seem to suggest that there are cases in which an agent has an obligation to perform an action even though she may not be able to perform that action, and thus OIC is false. In other words, ‘ought’ does not imply ‘can’. (shrink)

The paper argues that applications of the principle that “ought” implies “can” (OIC) depend on normative considerations even if the link between “ought” and “can” is logical in nature. Thus, we should reject a common, “factualist” conception of OIC and endorse weak “normativism”. Even if we use OIC as the rule ““cannot” therefore “not ought””, applying OIC is not a mere matter of facts and logic, as factualists claim, but often draws on “proto-ideals” of moral agency.

Does ?ought? imply ?can? for collectives' obligations? In this paper I want to establish two things. The first, what a collective obligation means for members of the collective. The second, how collective ability can be ascertained. I argue that there are four general kinds of obligation, which devolve from collectives to members in different ways, and I give an account of the distribution of obligation from collectives to members for each of these kinds. One implication of understanding collective obligation and (...) ability in the proposed way is that a group can be blameworthy for failing to realize its obligation even when no member of the group is blameworthy for failing to realize her obligation.

The two dogmas at issue are the Humean dogma that “‘is’ statements do not imply ‘ought’ statements” and the Kantian dogma that “‘ought’ statements imply ‘can’” statements. The extant literature concludes these logically contradict each other. On the contrary, it is argued here that while there is no derivable formal contradiction, the juxtaposition of the dogmas manifests a philosophical disagreement over how to understand the logic of prescriptions. This disagreement bears on how to understand current metaethical debate between realists and (...) non-realists about morality in a way not heretofore investigated. The conclusion is that realists have the resources to account for both dogmas, while non-realists, if they strictly adhere to the “is”/“ought” gap, cannot give an adequate account of why “ought” implies “can”.

During the 1980s, empirical social sciences and normative theory seemingly converged within ethical debates. This tendency kindled new debates about the limits and possibilities of empirical-normative collaboration. The article asks for adequate ways of collaboration by taking a closer look at the philosophy of science of empirical social sciences as well as normative theory development and its logical groundings. As a result, three possible modes of cooperation are characterized: first, the empirical assessment of conditions that actually necessitate the translation of (...) normatively derived basic principles into practice rules; second, the empirical assessment of conditions for application of a moral norm which are formulated by bridging principles; third, the empirical assessment of social practice which allows to measure whether adopted norms actually are implemented in practice or not and to encounter new moral problems which are in need of ethical guidance. Finally, the article defends a symbiotic position in Weaver ’s and Trevino's triad of possible approaches to empirical-normative collaboration in ethics. (shrink)
