5. Theory of Logic / F. Referring in Logic / 1. Naming / c. Names as referential
The only real proper names are 'this' and 'that'; the rest are really definite descriptions. [Russell, by Grayling]
     Full Idea: Russell argued that the only 'logically proper' names are those which denote particular entities with which one can be acquainted. The best examples are 'this' and 'that'; other apparent names turn out, when analysed, to be definite descriptions.
     From: report of Bertrand Russell (On the Nature of Acquaintance [1914]) by A.C. Grayling - Russell Ch.2
     A reaction: This view is firm countered by the causal theory of reference, proposed by Kripke and others, in which not only people like Aristotle are 'baptised' with a name, but also natural kinds such as water. It is hard to disagree with Kripke on this.
10. Modality / A. Necessity / 4. De re / De dicto modality
De re modal predicates are ambiguous [Lewis, by Rudder Baker]
     Full Idea: Lewis is perhaps the most prominent proponent of the view that de re modal predicates are ambiguous.
     From: report of David Lewis (Survival and Identity, with postscript [1983]) by Lynne Rudder Baker - Why Constitution is not Identity n25
14. Science / C. Induction / 1. Induction
If you eliminate the impossible, the truth will remain, even if it is weird [Conan Doyle]
     Full Idea: When you have eliminated the impossible, whatever remains, however improbable, must be the truth.
     From: Arthur Conan Doyle (The Sign of Four [1890], Ch. 6)
     A reaction: A beautiful statement, by Sherlock Holmes, of Eliminative Induction. It is obviously not true, of course. Many options may still face you after you have eliminated what is actually impossible.
