Argument

Objectivity has been constitutive of the modern scientific persona. Its significance has depended on its excision of standpoint, which has legitimated the scientist epistemically and sociopolitically at once. But if the nineteenth century reinforced those paired effects, the twentieth century brought questioning of both. The figure of Werner Heisenberg (1901–1976) puts the latter process on display. From the Kaiserreich to the Federal Republic of Germany, between quantum mechanics and interest group politics, his evolution shows an increasing openness to perspectival pluralism, together with an attempt to save some form of objectivity as discursive coherence. Heisenberg’s self-understanding and the reactions of his publics display the transmutation of the persona as objectivity was rethought. By the end of the day, speaking “as a scientist” would mean something different from what it had at the start.

Theorists of science and culture, seeking to explicate the implications of chaos theory, quantum mechanics, or special and general relativity, have drawn parallels to the constellation of intellectual and social phenomena collected in the concept of postmodernism. The notion thereby invoked of a postmodern physics is suggestive and worth exploring. But it remains ungrounded so long as the argument moves in the realm of parallels. Moreover, these discussions prove to be tacitly constrained by a preexisting genre of physicists' own literary production, a genre whose argumentative structures have been taken over implicitly into the subsequent exchanges. Attending critically in this way to the intellectual interests of the discussants — asking who it is that wants to constitute a postmodern physics — should open up more productive ways of framing the debate.
