The Uncertainty Principle
Within the realm of science, the uncertainty principle speaks of the fundamental limits of knowledge and measurement vis-à-vis the external world, and how the very act of seeing alters what is seen. Martin Herbert’s ‘The Uncertainty Principle’ is a collection of essays that reveals layers of unknowing and open-endedness within a diversity of contemporary art practices since the 1970s. If a work of art is always completed by the viewer, as Marcel Duchamp put it, then the works considered here equate completion with construction. In navigating us through a succession of artists’ approaches, Herbert also discloses how constructed experiences of “not knowing” can lead to deep engagements with a range of specific issues and themes: from history to politics, from epistemology to mortality.
