Evidence is the very core of Husserlian phenomenology, with the term “evidence” signifying for Husserl the phenomenological perspective on the question of truth. In contrast to the conventional philosophical understanding of “truth” in mainly epistemological terms, Husserl’s notion of “evidence”, as elaborated in his Logical Investigations (1900–1), is more essentially ontological, pointing to the way in which a phenomenon becomes clear to us in its constitution. Husserl’s main point in the Sixth Investigation was that we can “see” how evidence functions (...) when we compare something in the fullness of its presence with the emptiness of its absence. This paper considers the example Husserl offers of the room where the lights go off in order to illuminate the breakthrough for phenomenology achieved by Logical Investigations in its move beyond logic and epistemology to the primary level of pretheoretical experience as the reality of the real.
