Imperatives and Meaning
Published online by Cambridge University Press: 05 November 2010
Extract
In recent years philosophers have given a good deal of attention to imperatives. They have concerned themselves mainly with the logical grammar of sentences of this kind, that is to say their relations to each other and to interrogative and indicative sentences. Very often this topic has been raised in terms of the problem ‘Is imperative inference possible, and if so, what kind of inference is it?’. Many philosophers have contended that there are logically valid inferences that involve imperative sentences. Against this it has been argued that no such inferences are possible. It has even been held that there are no such things as imperatives at all – regarded, that is, as types of expression logically sui generis and independent of indicative sentences.

page 184 note 2 Hare does admit that the answer to the question ‘What shall I do?’ is not normally expressed in words, but that the agent ‘just acts’; however, he goes on to say that in order to give a satisfactory account of moral reasoning, we require an expression in words of what he leaves unuttered, and the form ‘Let me do a’ serves for this (Freedom and Reason, p. 55). It is significant that he later maintains that in making moral judgments, i.e. in saying that one ought to do a, one is ‘prescribing to oneself’, (op. cit., p. 73). In other words, what he leaves unuttered is an imperative.

page 189 note 1 I must mention here two articles by Ernest Sosa, ‘On Practical Inference and the Logic of Imperatives’, and ‘The Logic of Imperatives’ in Theoria, vol. xxxii, part 3 (1966). In these he employs the concepts of ‘directive’ and ‘satisfy’ in a way similar to that which I outline. Unfortunately the two articles appeared too late for me to profit by them.
