However, this reference to an aesthetic sense is far from being sufficient as a discussion of Ross' reference to "suitability" as a basis for connecting prima facie duties and actual duties in the argument of The Foundations of Ethics. Stratton-Lake's account only refers to the first place Ross discusses "suitability" in the third chapter of The Foundations of Ethics but Ross later returns to the topic in the seventh chapter of this book where he simply states that a "right action" means in general "one that is morally suitable to the situation". In returning to the topic here Ross differentiates between various senses of suitability referring to objective and subjective elements. The objective elements of the situation are the elements of it that suggest an action as suitable to the results we think it would produce whilst the subjective elements, by contrast, refer only to our thoughts concerning the probable results of alternative actions.
But this is not the only distinction Ross introduces since he goes on to include the difference between performing an action from a certain motive as involving suitability in a situation in a sense in which a mere action, regardless of motive, does not. This leads to the following apparent clarification:
Both the view that it is our duty to produce certain results, and the view that it is our duty to act from certain motives, are natural enough perversions of what seems to be the true view, that it is our duty to set ourselves to produce certain results. It is sometimes said that it is neither results nor motives but intentions that make actions right or wrong, and this is almost true. There is a certain danger in laying the stress on intention, since intentions may remain idle; but it would be true to say that the nature of what is intended in an act is what makes the act right or wrong. (pp. 159-60.)
Here Ross' prose almost catches one out as in the first sentence it takes a very attentive ear to note the difference between having a duty to produce certain results on the one hand and having the duty "to set ourselves" to produce results on the other. However the difference is nicely caught when Ross arrives at the notion that it is intention "in the act" that is at issue. This is a clear attempt to bring together the focus on the action alone (viewed as productive of result) on the one hand or the motive alone (viewed in some sense purely) on the other. And it is a further feature of consequence-sensitivity that some such attempt is needed. So perhaps Stratton-Lake is being far too hasty in suggesting that attention to the situation is too aesthetic an account of the connection between prima facie duties and actual duties. And, perhaps more needs to be filled in on the notion of "intention".
