If we overlook no consequences when we assess the act, and no relevant features when we generalize, can it matter whether we ask 'What would happen if everyone did the same?' instead of 'What would happen if this act were performed?'? David Lyons has argued that it cannot. Two examples are here articulated to show that it can. The first turns on the way consequences are identified and assessed and in particular on the treatment accorded 'threshold consequences'. The second example (...) turns on the way in which the 'social context' of the act (what others would be doing) is taken into account in the generalization. Also included is a formal theory of conditionals from which implications are drawn for utilitarianism and with which I attempt to dispel certain doubts concerning cases employed in my arguments.

This essay is arranged in three sections. In the first I consider interaction problems that can frustrate maximizers. My object here is to add to the kind of case discussed by Gauthier, another in which maximizers would not do well. In the next section I set out conditions under which ‘straight’ or ordinary maximizers could avoid their problems as surely and as easily as could Gauthier's ‘constrained’ maximizers. And in the last section I comment on the relative merits of straight (...) and ‘constrained’ maximization. Attention here is paid first to the suggestion that straight maximizers in view of their problems would choose not to be straight maximizers, would indeed choose to be ‘constrained’ maximizers, and that this shows that there is something wrong with straight maximization. Rejecting this inference, I turn in conclusion to the idea that it follows from the ‘incompleteness’ of straight maximization, from the fact that it is not always possible, that there is something wrong with it. This inference too is rejected. (shrink)

This paper addresses issues raised by recent discussion in normative ethics which concern relations between properties of individual actions and of certain groups of actions. First, an ambiguity common to ?everyone can? and ?everyone ought? is examined. Next, a similar ambiguity in talk about consequences is studied; here several procedures for identifying and evaluating consequences are compared. Then a notation that untangles the ambiguities is presented. Next, this notation is employed in an analysis of Marcus Singer's deduction of his generalization (...) argument. Finally, there is a study of the question as to whether or not conflicts are possible between Singer's generalization argument and the dictates of consequences of individual actions. The findings are that such conflicts are or are not possible depending upon how a certain restriction on generalization arguments is interpreted, and that in either case the proponent of generalization arguments is faced with problems.

The material in this note was developed for a first course in logie to illustrate a standard use of logie in analysis. The object was to present a not entirely trivial or artificial confusion that was amenable to resolution using only the tools of quite elementary logic-no modalities, no restrietions to extensional contexts. Copies o f The Problem were distributed. Then, on another day, A Solution.
