| 17050 | Tigers may lack all the properties we originally used to identify them [Kripke] |
| Full Idea: We might find out that tigers had none of the properties by which we originally identified them. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| 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. |
| 17051 | The original concept of 'cat' comes from paradigmatic instances [Kripke] |
| Full Idea: The original concept of cat is: that kind of thing, where the kind can be identified by paradigmatic instances. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: Kripke evokes Putnam at this point, since he is famous for this proposal. Note that Kripke uses the plural, invoking more than one instance. Presumably we must abstract the fur colours from the instances? |
| 17049 | 'Tiger' designates a species, and merely looking like the species is not enough [Kripke] |
| Full Idea: We can say in advance that we use the term 'tiger' to designate a species, and that anything not of this species, even though it looks like a tiger, is not in fact a tiger. | |
| From: Saul A. Kripke (Naming and Necessity lectures [1970], Lecture 3) | |
| A reaction: This is the 'baptismal' direct reference theory applied to species as well as to particular names. It seem to hinge on an internal structure being baptised, despite ignorance of what that structure is. Cf nominal essence? 'Tiger' denotes their essence? |
