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.
Clarification
A 'definite description' has the form 'the so-and-so'
Gist of Idea
The only real proper names are 'this' and 'that'; the rest are really definite descriptions.

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.
