Pauli makes a recapitulation of the axioms of the theory of probability and the law of large numbers and discusses the significance of the large deviation from the expected value. He also writes on the possibility of the influence on the results by the observer.

Pauli gives more remarks about certain problems of the form-factor theory.

Pauli writes on the manuscript of a paper by Thirring.

In this letter, Pauli gives further remarks on the spin-electron in a magnetic field. He also writes on the relation of physics to psychology.

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".

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 writes on the symbolism of the blue colour. He attempts at an interpretation of its significance for us.

Pauli gives further analysis of the entropy concept. The entropy of an ensemble is identical with the entropy of a single system. This under the condition that it concerns the measure of the information corresponding to the same ensemble.
