A Reaction

This sounds like a can of worms. If I baptise someone 'the tallest man in the room', and it turns out he isn't, I withdraw my baptism. Why would I never withdraw 'tiger'? I suppose Kripke is right.

14896 Kripke's metaphysics (essences, kinds, rigidity) blocks the slide into sociology [Kripke, by Ladyman/Ross]
17647 Kripke individuates objects by essential modal properties (and presupposes essentialism) [Kripke, by Putnam]
5450 For Kripke, essence is origin; for Putnam, essence is properties; for Wiggins, essence is membership of a kind [Kripke, by Mautner]

7761 Test for rigidity by inserting into the sentence 'N might not have been N' [Kripke, by Lycan]
7693 Kripke avoids difficulties of transworld identity by saying it is a decision, not a discovery [Kripke, by Jacquette]
5821 Saying that natural kinds are 'rigid designators' is the same as saying they are 'indexical' [Kripke, by Putnam]
14068 If Kripke names must still denote a thing in a non-actual situation, the statue isn't its clay [Gibbard on Kripke]
10436 A rigid expression may refer at a world to an object not existing in that world [Kripke, by Sainsbury]

6765 Nominal essence may well be neither necessary nor sufficient for a natural kind [Kripke, by Bird]
16395 Kripke separated semantics from metaphysics, rather than linking them, making the latter independent [Kripke, by Stalnaker]
10559 Kripke's modal semantics presupposes certain facts about possible worlds [Kripke, by Zalta]
