Thirring thanks BR for his letter of 6 March and the invitation to Quebec, though, as he has informed Rotblat by telephone already, he is unable to join the conference this time.

Thirring details his work, such as organizing a meeting of the Pugwash group in Vienna, as "... it is meant to explain that all my work will be dedicated to exactly the same goals towards which Socrates, Einstein, you and many others were striving."

Thirring visited BR on 27 September 1952.
