\brief{Rudolf Carnap an Otto Neurath, 22. Januar 1940\labelcn{1940-01-22-Carnap-an-Neurath}}{Januar 1940}

\anrede{Dear Neurath:}

\haupttext{
I received your two cables and inferred from the second that my letter of Nov.
29\textsuperscript{th} finally arrived.

Kaila sent me his book “Den Mänskliga Kunskapen” (Söderström, Helsingfors). It seems to me a good introduction into logical empiricism written for a wider public; but taking into consideration also some more technical questions. It will appeal to many readers because it considers the historical background, from Euclid and Aristotle on, much more than any other publication of our movement.

\noindent Kaila asked about the possibility of an English translation. In this case he would change the book somewhat. But his letter was written in the beginning of September, and I do not know about his present conditions. It seems to me, an English translation would be very desirable. But I cannot make a final judgement about the book because my Swedish reading is rather slow, and, therefore, I read only certain parts. I suggest that you ask Jørgensen and Næss for judgement. I suppose that they have the book.

Please let me know when you got their opinions, and then we may decide whether or not an English translation of the book would be suitable for our Library.~\neueseite

Do you have the material of the Congress discussions? Did we not plan to send to everybody a typescript of his remarks? I did not get anything so far. Or did you give up the intention of publishing the discussion?

Best thanks for your New Years greetings. I am very pleased to see that the elephant waves the flower gaily. I infer from it that he is as well as it is possible under the present circumstances.

\briefanhang{\neueseite{} \uline{Supplementary remarks concerning “Studies in Semantics”}

\medskip

\noindent The ms. of Part I is now finished. It will be typed during the next weeks, then I shall send it to some friends, and then perhaps make some changes. Thus, I suppose, it will not be ready for print before March or April. I have added two appendixes to be printed in small type. One indicating further problems which will perhaps be dealt with in later Parts; the second explaining the changes which are to be made with respect to my book “Logical Syntax\fnA{\original{Science}}” from the new point of view of semantics.

According to my calculation, the present ms. of Part I would have about 130 printed pages of the size of the Encyclopedia or about 120 pages of the size of the “Logical Syntax\fnA{\original{Science}}”. What will be the size of the monographs in the “Library”? How many English words on a page?
