This paper offers a critique of David Gauthier’s contractarian moral theory. I point out morally counter-intuitive implications of Gauthier’s theory – for example, with respect to societies with slavery or concerning the protection of animals – as well as theoretically unattractive features, such as the overly optimistic assumption of translucent agents. However, contractarian moral theories can be improved by correcting the theoretically unattractive features. Moreover, though some morally counter-intuitive implications cannot be avoided, whether we should accept these implications ultimately depends on whether an instrumentalist account of practical reason is defensible and how morality relates to practical reason. Thus, contractarian moral theories cannot be refuted as easily as one might think at first.

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.
