The Enlightenment brought a paradigm shift from monocular to binocular vision and with it an understanding that ways of seeing involve issues of focus but also, we believe, a growing understanding that with focus some elements will be “out of focus,” or unseen (or maybe even discarded, lost, forgotten, or disappeared). At the ICI, we employ a range of visual tools that slightly distract or disrupt our usual ways of seeing. We believe these devices produce not only small slips of the eye but also epistemological and ontological slips of the mind as well.
