The Idea of Rigorous Science in Husserl’s Phenomenology and Its Relevance for the other Sciences

In this paper I intend to grapple with the idea of philosophy as rigorous science from the point of view of Husserl‟s phenomenology in order to show that this idea may have an important contribution to the way in which the scientific character of sciences in general, and of human and social sciences in particular, is being conceived. As rigorous science, phenomenology emphasizes and investigates the a priori context of other sciences. In this way, it plays a vital role in the development of every particular eidetic upon which any sciences rely. This eidetic (or the eidetic layer of any mature science) embraces the goal and strives to reach the objective of determining the valid sense of the fundamental notions used by the scientist in his research, without, nevertheless, stirring a radical questioning of this sense and of the ultimate validity of these notions. To define them requires passing from the usual level of inquiring of that particular science (the processes of dealing with facts and experiments) to the level (or meta-level) of a radical reflection on the sense or the meaning of the basic notions of the science in question (its own foundations). Philosophy as rigorous science connects the researcher´s assertions not only to the empirical state of affairs envisaged by his work, but, moreover and in a fundamental way, to their noematic content, to their intrinsic intentional meaning. Therefore, the idea of rigorous science elaborated in Husserl‟s phenomenology is heavy with the potential of clarifying the foundations and stakes of the research undertaken by the other sciences.
