October 30, 1924

Dear Solovine,

You will receive by mail the brochure of Klass. d. ex. W. and the book…by A.M. That should be enough biographical material. I was always interested in philosophy but only as a sideline. My interest in science was always essentially limited to the study of principles, which best explains my conduct in its entirety. That I have published so little is attributable to the same circumstance, for the burning desire to grasp principles has caused me to spend most of my time on fruitless endeavors. The commission of the League of Nations was better than I thought. There is still hope that things will be better in Europe.

Cordial greetings from
Your         

A. Einstein
