In any analysis of L'Être et le Néant, it is imperative that Sartre's use of phenomenological method be considered and evaluated. It is not a coincidence that phenomenology appears in Sartre's ontology, for we have been advised in the subtitle of EN, "Essay in Phenomenological Ontology," of his intention to make use of the phenomenological method. Since Sartre appears to mean by phenomenology the special discipline formulated by Husserl, it will be well to begin our discussion with a brief resumé of Husserl's position.
