Some philosophers hold that objective consequentialism is false because it is incompatible with the principle that “ought” implies “can”. Roughly speaking, objective consequentialism is the doctrine that you always ought to do what will in fact have the best consequences. According to the principle that “ought” implies “can”, you have a moral obligation to do something only if you can do that thing. Frances Howard-Snyder has used an innovative thought experiment to argue that sometimes you cannot do what will in fact have the best consequences because you do not know what will in fact have the best consequences. Erik Carlson has raised two objections against Howard-Snyder’s argument. This paper examines Howard-Snyder’s argument as well as Carlson’s objections, arguing that Carlson’s objections do not go through but Howard-Snyder’s argument fails nonetheless. Moreover, this paper attempts to show that objective consequentialism and other objectivist moral theories are compatible with the principle that “ought” implies “can”. Finally, this paper analyses a special kind of inability: ignorance-induced inability.

Norbert Hoerster has tried to show on the basis of what I call special and general interests that it is rational to endorse moral judgements. I argue that Hoerster’s attempt to vindicate the rationality of moral judgements fails. By appealing to special interests Hoerster can only establish the rationality of endorsing judgements that – by Hoerster’s own standards – are not moral judgements because they do not pass the test of generalization. While the appeal to general interests, on the other hand, indeed establishes the rationality of endorsing judgements that pass the test of generalization, it does so only for some but not all people; for this reason, the vindicated judgements do not qualify as moral judgements either.

Frank Jackson has put forward a famous thought experiment of a physician who has to decide on the correct treatment for her patient. Subjective consequentialism tells the physician to do what intuitively seems to be the right action, whereas objective consequentialism fails to guide the physician’s action. I suppose that objective consequentialists want to supplement their theory so that it guides the physician’s action towards what intuitively seems to be the right treatment. Since this treatment is wrong according to objective consequentialism, objective consequentialists have to license it without calling it right. I consider eight strategies to spell out the idea of licensing the intuitively right treatment and argue that objective consequentialism is on the horns of what I call the licensing dilemma : Either the physician’s action is not guided towards the intuitively right treatment. Or the guidance towards the intuitively right treatment is ad hoc in some respect or the other.
