This article reflects on the way B. Welte approaches the fundamental Mystery of Being: his successive reflections on the Nothing which precedes our existence, on the need to explain the Something, the series of the fundamental rationale and the decisive question about the Foundation - what it puts into question, and on what it asks itself questions. After having thematised the logic of such an approach, Brito acknowledges its present relevance and the validity of its phenomenological starting point. He also underscores the ontologically questionable character of any primacy granted to the Nothing, and the kind of rebellion against Transcendence which can sometimes be found in the trial of the Nothing.
