Extract

A designator a of an object x is rigid in Kripke's sense if and only if (i) for every possible world w, if x exists in w, then a designates x with respect to w and (ii) there is no possible world with respect to which a designates something other than x. Alternatively, but to the same effect, a is rigid just in case neither the sentence:

a might have existed and not have been a

nor the sentence:

Something other than a might have been a

has an interpretation on which it is true. This alternative seems to me preferable: the concept of designation with respect to a world is difficult and occasions certain problems (about which something will be said later), but these problems do not arise on this explanation.

2 The conditions are independent: ‘the actor Paul Newman’ satisfies the second but not the first, and ‘the x such that x = Paul Newman if he exists and x = 9 otherwise’ satisfies the first but not the second.

5 See Naming and Necessity, 7-8. Kripke does allow that a terminology “according to which uses of phonetically the same sounds to name distinct objects count as distinct names … may have a great deal to recommend it for theoretical purposes,” even though it “certainly does not agree with the most common usage.“

16 In ‘On Denoting,’ Mind 14 (1905) 479-93, Russell gave up the doctrine that proper names are purely designative, but continued to hold that there are singular propositions. Even after his abandonment of propositions, which occurred not much later, true singular propositions in effect remained in his ontology, in the guise of certain ‘facts,’ or ‘complexes.’

17 It might be said that the words ‘piece of chalk’ serve merely to aid in the identification of the object of reference and hence that the proposition asserted requires for its truth only that the object of reference, whether or not it is a piece of chalk, be white. I am inclined to disagree, on the ground that what is said cannot correctly be said to be unqualifiedly true unless the object referred to is a piece of chalk. But I doubt that much hangs on the point.

19 The form of expression discussed here is sufficiently hard to avoid that even enemies of singular propositions sometimes fall into its use. Frege, hardly a friend of singular propositions, lapses on a couple of occasions. Thus: It is not necessary that the person who feels cold should himself give utterance to the thought that he feels cold. Another person can do this by using a name to designate the one who feels cold.(Posthumous Writings, trans. Long, Peter and White, Roger with the assistance of Hargreaves, Raymond [Oxford: Blackwell 1979], 134-5Google Scholar. My emphasis.) And: “Now everyone is presented to himself in a special and primitive way, in which he is presented to no one else. So, when Dr. Lauven has the thought that he was wounded ….” (McGuinness, B. ed., Collected Papers, trans. Black, M.et al. [Oxford: Blackwell 1984], 359. My emphasis.)Google Scholar

20 Russell did not use ‘propositional function’ consistently, even within the confines of a single book. I follow the use described at 508-10 of The Principles of Mathematics, though of course there are others in that book.

21 I think it is fair to attribute this view to Moore. See his Lewy, Casimir ed., Lectures on Philosophy, (London: Allen & Unwin 1966), 129-31Google Scholar.

22 On this point I have benefited from discussions with Aviv Hoffman, though he is firmly opposed to the position toward which I am inclined.
