Rudolf Carnap an Bertrand Russell, 27. Februar 1926 Februar 1926

I enclose the contents and some pages of a new manuscriptB, in which I trie [sic] to make an application of your logic for the construction of an epistemological system. If you would wish to read the manuscript I would be glad to send it to you and to receive your critics upon it.

Please send me back these pages or send them to Mr. WhiteheadPWhitehead, Alfred North, 1861–1947, brit.-am. Philosoph if you think that he will be interested in this matter.

Two years before you helped me kindly in getting a copy of the Principia MathematicaBRussell, Bertrand, und Alfred North Whitehead!1910@Principia Mathematica, Cambridge UK, 1910–1913, 2. Aufl., 1925–1927. I wish to say you my best thanks for the great help I received by this work especially in the mentioned manuscriptB, although I am not sure that you will be agreed with my proceeding in applying your logic.
