Pauli gives critical remarks and some calculations concerning Borns' electrodynamics and his ideas on gravitation.

Pauli replies to Born's question about a possible publication in Helv. Phys. Acta. He expresses his interest in some results (spin) of Born's field quantization.

Pauli gives some calculations on an integral used by Born.

Pauli returns to a problem discussed at the Florence conference concerning irreversibility and the H-theorem.

Pauli praises Born's lecture "Der Mensch und das Atom".

Pauli refers to Einstein's article in the de Broglie volume and rejects his conclusion that the results of quantum physics are not complete.

Pauli continues his critical discussion of Einstein's philosophy of physics. Pauli is against his "realistic" metaphysics.

Pauli writes about Weyl's death, on December 8. He mentions Weyl's 70th birthday and Pauli's address to this occasion.

Pauli refers to a discussion he had with Born, Klein and Kirkwood. He also describes his own objections to a talk given by Born during a conference in Florence (properties of a certain operator). The letter touches briefly on other matters, including Born's theory of reciprocity.

Pauli declines Born's proposition to become a member of a "political party with a red stamp" or to sign "any open letter". Instead of taking part to a East-West world division, Pauli would more encourage a synthesis between asiatic wisdom and occidental sciences, which is more application oriented. He gives some thoughts on the behavior of a scientist on political questions. He also talks about his interest in Fröhlich's theory of supraconductivity.
