In his early essay on transcendence of the ego, Sartre attempted to follow Husserl’s Logical Investigations and to draw the consequences of his phenomenological criticism of subjectivity. Both authors have emphasized the elusiveness of the self as a result of intentionality of consciousness. However, Sartre’s analysis of ego led him quite far from Husserl’s philosophical project, insofar as it was somehow already raising the question about the moral nature of the self, and was thus establishing the basis of the conception of moral consciousness that has been displayed later in Being and Nothingness. This article stresses the importance of such a turn in Sartre’s philosophy, which reorients him from a strict description of consciousness toward a moral assessment of the structure of the self

The purpose of this book is to investigate the roots of phenomenology and to analyse, from a historical and systematic point of view, the reasons that enabled Husserl to set down in his Logical Investigations the conditions of a strictly descriptive philosophy. The ‘breakthrough’ of phenomenology was made possible by Husserl’s investigations on the specificity of logical forms, and was grounded upon his ability to establish in the Logical Investigations a descriptive distinction between sensitive and categorial forms. Such distinction allows Husserl to account for the possibility of a certain kind of adequacy between speech and perception that is necessarily involved in phenomenological description. Indeed, as a descriptive activity, phenomenology entails the opposition between two fundamentally different modalities of intentionality that both take part in description: intuition on the one hand and signification on the other. By making the adequacy between signification and intuition possible, ‘categorial intuition’ not only sheds new light on the relations between thought and perception, or between seeing and thinking, it also legitimates phenomenological description as a philosophical method. This book proposes a new and revisited reading of the Logical Investigations by examining Husserl’s reform of the theory of categories and its relation to the phenomenological method of description.
