Hans Blumenberg, “Light as Metaphor for Truth: At the Preliminary Stage of Philosophical Concept Formation,” in Modernity and the Hegemony of Vision, edited by D. M. Levin (Berkeley: University of California Press, 1993), 30–54 This reading explains how light is used to expose, similar to its self title that it is used as a metaphor for truth. Light can only be seen in what it is making it visible, which can be thought of how it is only present when it is putting something else on the spotlight.
