In the late 1920s, the theoretical physicist Werner Heisenberg wrote a series of scientific papers proposing that the universe could not be known with perfect certainty. His theory, which came to be known as the “uncertainty principle,” blamed the limitations of scientific measurement. Perfect knowledge was impossible, Heisenberg theorized, because scientists changed the quantum universe through the very act of measuring it. Observers could not watch the universe voyeuristically, as though from the sidelines. To sight quantum reality was to alter it.
Beyond Religious Freedom: The New Global Politics of Religion introduces something like an uncertainty principle into the targeting of religion in international relations. In a manner not dissimilar to Heisenberg, Hurd argues that, in the process of singling out religion for support or censure, governments, lawmakers, advocacy groups and others alter the complex field of social relations that they purport to manage. They change religion through the process of sighting it.
