Dear Charles:

In the meantime you will received my letter of Jan. 23rd and Ina\index{Carnap,
Ina}'s of 26th.

\hspace{15pt}I am returning Neurath's letter. I am not sufficiently acquainted
with Gerard's\index{Gerard, Ralph} work and views in order to pass judgment about
him and his suitability as an author for the Encyclopedia. But I am willing to
accept your suggestion that we ask him. I am simultaneously writing this to
Neurath by air mail.

\hspace{15pt}I am surprised to learn that Santillana\footnote{George de
Santillana (1902-1974) was an Italian-American historian of science. He wrote a
monograph (to be more precise: the first part of it on rationalism) for the
\textit{IEUS }with Edgar Zilsel (1941): \textit{The Development of Rationalism
and Empiricism}. Chicago: University of Chicago Press (\textit{IEUS,
}II-8).}\index{Santillana, George de}'s ms. is already finished. I was not quite
satisfied with certain features in his previous abstract concerning the
development of mathematics, and especially the nature of geometry from the point
of view of science. I believe that at that partition of the subject matter had
not been cleared up, and, therefore, I said (I believe wrote so to Neurath) that
I wanted to postpone my remarks S. would write a new abstract. But I have not got
anything from since that time. I hope, I may now make these remarks when I shall
have read the ms., although they might possibly involve greater changes in the
ms.

\hspace{15pt}I agree with you that the next unit of the Enc. should not be
announced until the present one is much nearer to completion.
