postulate of absolute knowledge (pp. 133–134).

251. From Paul G. Tomlinson[1]
Princeton, New Jersey, Sept. 30, 1921
My dear Professor Einstein—
On July 6 I wrote you inquiring when we might expect to receive the manuscript
of your
I have had no reply to this letter. A number of people have been
inquiring when the book will be ready, and we are considerably alarmed at the long
delay in the receipt of your manuscript, which we were led to believe would be in
our hands within a month after the lectures were delivered. The importance of the
book will undoubtedly be seriously affected unless we are able to publish it within
a reasonable time and I strongly urge upon you the necessity of sending us the copy
at your earliest convenience. I should appreciate also the favor of a reply from you
stating when we may expect to receive it.
Yours sincerely,
Paul G. Tomlinson

expressed unhappiness with his slow progress (see 7 September 1921 in Calendar).
