Lüders thanks Pauli for his letter of 16 June and his offprints on field theories covariant with regard to the Lorentz group.
Sin títuloKröner makes some additional comments on their conversation of 14 July. He speaks about the contents of consciousness, phenomenalism and realism, reality in quantum physics, the borderline between science and the absolute. He opposes Weizsäcker's interpretation of experiments.
Sin títuloPauli discusses, among other things, Schopenhauer, Greek and Buddhist philosoph, and the oppositions phenomenism-realism, consciousness-existence, observer-observed object, etc.
Sin títuloPauli replies to a letter of the 25 July 1954. He explains his critical attitude to ontology but he conceeds that ontology reflects an intrinsic need of man to overcome the tension between the "Internal" and the "External".
Sin títuloBudini thanks Pauli for his letter. He is now convinced that the eigen-functions in question are not orthogonal to each other.
Sin títuloPauli sends his impressions from the Solvay Congress. He writes that the pioneers of quantum physics have become their own epigones, they lost the feeling of intellectual adventure and acquired the attitude of technicians.
Sin títuloFierz gives a correction to what he said in Basel about gravitational waves, in particular cylindrical waves.
Sin títuloFierz sends remarks about Einstein's cylindrical waves, with reference to Weyl's paper published in: Annalen der Physik (1917) 54.
Sin títuloW. Pauli mentions discussions in Altdorf about biology, evolution, etc.
Sin títuloRosenfeld talks about Pauli's contribution to the forthcoming Bohr Festschrift.
