This contribution aims to offer a hypothesis for reading the question of evil/negativity in an essentially theoretical key. The focus is on the anthropological-existential dimensions of the question. These will be examined with the aid of methodological tools of a phenomenological character. The inquiry will strive to bring to light four figures of evil/negativity by grasping their appearance within some crucial junctures of human existence. The first figure comes to the foreground against the backdrop of semantic crises – which sometimes become full-fledged catastrophes – which are produced within “regional scenes” of human existence. The second figure of evil/negativity becomes present in the hypothesis of lack of sense or the absurd which weighs heavily and constantly on the existential “pluriverse” when it is grasped globally. The third figure stands out in an upsetting way in the events, both cosmic and anthropological, of the reduction -or even the negation- of that physiological tension toward differentiation that seems to intimately constitute the existential “pluriverse”. The fourth and last figure of negativity properly consists of moral evil, which is reinterpreted in the terms of a free and voluntary human choice of being-closed-to that radical alterity which constitutes, at its core, the very ontological profile of the human being.
