\brief{Bertrand Russell an Rudolf Carnap, 26. April 1929}{April 1929} %26th April 1929. \anrede{Dear Dr. Carnap,} \haupttext{Thank you very much indeed for sending me your ``Abriß der Logistik nach dem System der Principia Mathematica''\IC{\logistik}, which I have looked at though I have not yet had time to read it properly. Your book on the ``Logical Structure of the World''\IC{\konstitutionstheorie} duly reached me; as I have been very much occupied with unphilosophical labours, I have not had time to read it as it deserves, but from looking into it, I feel inclined to suppose that its views are those which I ought to hold, in the sense that they are the logical working out of premises which I accept. As soon as I get the necessary leisure, I shall hope to study both books with care. I am grateful to you not only for sending me the books, but for what you are doing to make the logistic point of view known in Germany.} \grussformel{Yours very truly,\\ Bertrand Russell} \ebericht{Brief, msl., 1 Seite, \href{https://doi.org/10.48666/871195}{RC 102-68-18}; Briefkopf: \blockade{fac simile} msl. \original{26th\,April 1929}.}
