ALS, one page both sides, 5.25 x 7, February 21, 1924. Letter to important philosopher and physicist Moritz Schlick. In part: “My 'External World' has not been translated into German, & I should be very glad if you could get it translated. The copyright, however, does not belong to me…I should wish to make a few corrections in it but they would not be of great importance. I much regret what you tell me about the magazine. My French friend from whom I hoped for a contribution in English has just died…I shall be very sorry indeed if it becomes necessary to abandon any part of your original intentions.” In fine condition, with adhesive remnants to the upper left corner. Russell's Our Knowledge of the External World had been published a decade earlier as a compilation of lectures he delivered in the US in which he questioned the very relevance and legitimacy of philosophy. In it he investigated the relationship between ‘individual’ and ‘scientific’ knowledge and questioned the means in which we have come to understand our physical world. Schlick embraced many of Russell's ideas, such as logical atomism, upon which he formed the basis of the famous Vienna Circle philosophy discussion group. Pre-certified PSA/DNA and RR Auction COA.
