Translated from German into English, in full: Dear Mr. Silberstein! Naturally I think back to our personal acquaintance. -On the cosmological problem and the term Λ the following remarks: 1.) From the point of view of my latest results in general relativity, the introduction of the Λ term is far more natural than it originally was. This emerges from a work that is right now being printed at the Academy. 2.) In Pasadena this winter I changed my position on the cosmological problem.
