Pauli is preparing for his lecture in Mainz. He has read a book by R Otto on "West-eastern mysticism" (1926), and he writes about its contents. He writes a long excursion on the problem of salvation versus science. He believes cognition and scientific cognition tend to come nearer to each other.

Pauli comments on a paper by Farquhar and Landsberg "On the Quantum statistical ergodic and H-theorem" which refers to Fierz's work. He also makes additional remarks on Fierz's paper on the H-theorem.

Pauli looks forward in meeting Destouches on March 3. He thinks that he could reach an agreement with him on the points that are under discussion.
