Pauli writes on the limitations of the general theory of relativity, on the concept of space in the Renaissance, on the concepts of the neoplatonic world-soul and its replacement by mathematics and measurement in the 17th century, on the modified return of these neoplatonic ideas in quantum theory and on the need for a new conception and a new terminology, as e.g. "automorphism".

In this letter Pauli insists on the full publication of the doctoral student Talmi's dissertation published in: Helvetica physica acta. He also writes about the last seminar in Zurich.

Pauli writes on Bohm's repetition of de Broglie's earlier ideas and on the statistical and non-statistical meaning of the $\Psi$-function.

Pauli writes on Jung's synchronicity and its interpretation. He says that pycho-physical connections should be treated as a special case of reproducible non-causal arrangements (which also includes quantum physics).

Pauli makes some remarks about the magical origins of the word "influence" (influxus). He adds some considerations and calculations on the form-factor theory.

Pauli makes more calculations concerning the form-factor theory. He also gives some critical remarks about the limitations of the theory.

Pauli comments on a letter by Fierz about the H-theorem.

Pauli's letter contains a mathematical calculation that corrects a remark made by Fierz.

Pauli asks some questions about the H-theorem in connection with a letter written by Panofksy concerning the Renaissance philosophers.

This is a letter of condolence on the death of Fierz's father.
