In this paper, I examine, in five parts, the nature and function of evidence in Husserl’s phenomenology of existence. By “evidence” I understand the intentional achievement of self-giving in Husserl’s sense, and by “phenomenology of existence” I understand the branch of his philosophy that addresses the question concerning a meaningful life. In Part One, I propose that Husserl’s philosophy includes a phenomenology of existence. In Part Two, I employ a selection of texts from Grenzprobleme der Phänomenologie to sketch the basic outlines of his phenomenology of existence. In Part Three, I demonstrate that Husserl develops a concept of evidence rich enough to encompass the evidence appropriate to his phenomenology of existence. In Part Four, I investigate the way in which Husserl appeals to what one may describe as “existential evidence” to ground his manner of apprehending the world as he sees it. In Part Five, I expand the horizon of the investigation by situating “existential evidence” – the “given” that keeps on giving – in the context of other kinds of evidence more familiar to scholars and students of Husserl’s phenomenology.
