[FOM] Russell and Skolem's paradox

[G Aldo Antonelli]

Alasdair Urquhart says:

> As far as I know, Russell never commented at all on Skolem's work,
> nor do I think that he was even aware of it.  The second edition of
> PM (1927) contains a list of contributions to mathematical logic
> since the publication of the first edition of PM.  Neither Lowenheim

> Brouwer, Tarski, Bernstein, Konig, C.I. Lewis, Sheffer, Nicod,
> Wittgenstein and Schonfinkel.

I remember being told that Russell thought that the greatest technical 
advance achieved between the first and second edition of PM was the 
introduction of Sheffer's stroke.

Surely Alasdair can confirm this, if true, which would speak to the 
extent of Russell's involvement in technical advances in logic after the 
first edition.
