It is evident that the purposes which I have said might be served by making a logically necessary statement in the form of a contradictory of an inconsistent statement could be served equally well by making it in the form of a second-order statement of logical appraisal. These would, in fact, be different ways of saying the same thing, or of making the same appraisal.

Judgements about how probable it is that if A, B, seem to coincide with judgements about the 28 Do Conditionals Have Truth-Conditions? 29 the negative result too, but hardly perspicuously. My aim, in trying to extract an intuitively compelling argument from a somewhat baffling piece of algebra, is not only to make this way of thinking about conditionals more widely, and more deeply, appreciated.
It is also, by weakening the assumptions, to provide a stronger proof of the negative result. I hope to render the positive thesis more plausible, too, by presenting it less technically. It should not need emphasis that in the conditional we have an indispensable form of thought, which plays a large part in both theoretical reasoning about what is the case and practical reasoning about what to do. Its basic role may be described thus: we are not omniscient; we do not know as much as it would be useful for us to know.
