Collected works. - Complementarity beyond physics (1928-1962)

Part II contains articles of a more general cultural interest. Some of these show that Bohr regarded the complementary perspective to be of value also outside the scientific sphere.

Part III contains the articles Bohr wrote about the great Danish philosopher Harald HГёffding. These short papers are presented in a section on their own because of the continuing discussion in the history of science about HГёffding's possible influence on Bohr's work in physics and his whole scientific approach.

Part IV comprises articles illuminating the history of 20th century physics. Bohr had great veneration for his predecessors and teachers, and he prepared these articles with great care.

Part V contains correspondence relating to the material in Parts I through IV. As in previous volumes an inventory of relevant unpublished manuscripts held at the Niels Bohr Archive constitutes an appendix to the whole volume.
