Abstract

The article deals with two problems that arise within moorean style act-utilitarianism (a.u.): (i) how is the notion of 'the alternatives to' a particular action to be explicated? (ii) how should a.u. be formulated in order for it to validate the laws of standard deontic logic? it is argued that these intertwined problems can be solved only if the traditional formulations a a.u. are rejected in favor of some new and more viable ones. in the literature the two problems seem to have been seriously considered only by bergstrom and castaneda. in a final section the author extends his new versions of a.u. to 'sequences' of "single" particular actions and argues for the necessity of working with 'tensed' deontic notions as well as for a combination of deontic logic with tense-logic
