- the twenty-third letter of the English alphabet, is usually a consonant, but sometimes it is a vowel, forming the second element of certain diphthongs, as in few, how. It takes its written form and its name from the repetition of a V, this being the original form of the Roman capital letter which we call U. Etymologically it is most related to v and u. See V, and U. Some of the uneducated classes in England, especially in London, confuse w and v, substituting the one for the other, as weal for veal, and veal for weal; wine for vine, and vine for wine, etc. See Guide to Pronunciation, §§ 266-268.

Sorry, no etymologies found.
Thus, the sentence ˜I am a philosopher™ is false with respect to c and w, but true with respect to c and w*.
But what is the intuitive connection between w and w*?
To provide the required counterexample, just consider a model in which A holds at w, B doesn't hold at w, and A doesn't hold at w*.
(SÂ¬) vw (Â¬A) = 1 if and only if vw* (A) = 0, that is, Â¬A is true at a world w if and only if A is false, not at w itself (as it happens with standard negation), but at its twin w*.
Given a world w, the involution operation produces a world w* which is, in a sense to be specified, its “reverse twin”.
Stalnaker's semantics uses a "selection function", F, which selects, for any proposition A and any world w, a world, w², the nearest (most similar) world to w at which A is true.
"If A, B" is true at w iff B is true at F (A, w), i.e. at w², the world most similar to w at which A is true.
The propositional concept corresponding to this statement will yield the truth for any pair of worlds w, w² such that there is an x that is referred to as ˜that man™ in w, and x is sitting in w².
Suppose Moe is sitting in the actual world w and standing in alternative world w², while Curley is standing in
But Klagge took that to show that w and w* do not provide a counterexample to the strong supervenience of A on B after all.
