In the first part of L'Être et le Néant Sartre described mainly the Being of the pour-soi and its relation to the en-soi. This study, however, has left him with the necessity of rescuing his ontology from the charge of solipsism, for he has explicated only the Being of one's consciousness with no bridge established to the consciousness of Others. The danger is that "Sartre has followed so closely the idealistic conception of Self-consciousness (cogito) as the transcendental origin and "creator' of all Being that he constantly faces the danger of transcendental solipsism."¹ In facing the problem of solipsism in EN, Sartre analyzes the existence of the Other and the relations between my Being and the Being of the Other.²
