Pauli admits his blunder in predicting the conservation of parity and attempts to explain the psychological background. He writes on the symbolism of mirror-images, on his recent correspondance with Heisenberg on the dipole ghosts and psychological remarks about it.

Pauli asks about a letter by two Italian physicists concerning Neumann's macro-observables. He writes on a gnostic myth about the mirror image of Nous which appears as Physics. This symmetrical relation forms the basis of physics.

Pauli writes about a brief question concerning a paper by two Italians.

Pauli writes on the physical ideas of the Stoics, their "pneuma" and determinism and field physics as against the Greek atomism. The modern field physics is a direct descendent of the Stoa and the old conflict between atomists and continuists still exists today.

Pauli replies to Fierz's letter of the 21 November 1957.

Pauli writes on a certain isomorphic relation (conservation of baryon number and rotary group of isotopic spin). He talks about his intensive work a new theoretical interpretation of the isospin-space.

Pauli reacts positively to the idea of Fierz's going to CERN. He expresses on the whole a favourable opinion on the work and on the atmosphere in CERN.

Pauli is positive about Fierz's ideas which seem to be promising for weak coupling.

Pauli writes on his discussion with Enz concerning Fierz's calculations.

Pauli gives further calculations in connection with Majorana's theory. He also writes on his calculations with Weisskopf on the positron theory.
