To a greater extent than any other scientist of the twentieth century Bohr perceived the institution of science to which he dedicated his life to be a profoundly political force in the world.

Totalitarianism, in Hannah Arendt’s powerful image, drove toward “destroying all space between men and pressing men against each other.”923 It was entirely in character that Bohr, at a time of increasing danger, publicly opposed that drive with the individualistic and enriching discretions of complementarity.
