The logic of Logic and the Basis of Ethics

Abstract

What is it that is doing the real work in Prior’s 1949 book Logic and the Basis of Ethics? As Prior’s title announces, it seems that the answer is logic. But what exactly does this mean to Prior?

Notes

  1. 1.

    Prior does not elaborate this curious comment about necessity. One would have thought that, at least in Moore’s eyes, it would be equally a fallacy to say that ‘being good is necessarily equivalent to being \(\mathrm{X}\)’ where X is any natural property.

  2. 2.

    In fact, the particular reference in Chapter V of LBE to Principia Mathematica does not get into greater technical detail than to consider whether the sentence ‘I promise’ is “a statement about an object, or a statement about a statement; or perhaps more accurately, it is not clear whether it is a statement about an object, or is itself the object which the statement is about” (LBE, p. 50).

  3. 3.

    This makes LBE especially interesting because in LBE he often sounds very much like an ordinary language philosopher himself.

  4. 4.

    Mary Prior recalls going to the 1951 meeting of the ‘Australasian Philosophy and Psychology Society’. She explains:

    We were amazed when Jack Smart, freshly out from Oxford, strode across the room to congratulate Arthur on Logic and the Basis of Ethics, which he announced was being much discussed in Oxford (Prior 2003, p. 295f).
