What is philosophy in general, or what is the specific of philosophy? For Aristotel, philosophy is the knowledge of the first principles and causes - those supreme principles which explain the whole existence(Coltescu, 2002 p.160 ). For Kant, philosophy is knowledge by concepts; or the search of the limits of our cognitive capacities. For Hegel, philosophy is the rational knowledge of absolute. For Wittgenstein, philosophy is the activity of eludation of thoughts. For analitical philosophers, philosophy is the analysis of scientific language or of common language. For Heidegger, philosophy is the existential analytics , that is investigating of those modes of being that are proper to human existent(Dasein);
       For Frankfurt school representatives (Marcuse), philosophy is the critical theory of modern society and of forms of reification and human alienation in the background of this society. Coltescu considered that "In its esence, philosophy is this reflection, this meditation by which we want to understand, to distinguish the sense of world and of our proper existence---and by understanding, to liberate us, to conquer our spiritual autonomy"(Coltescu 2002, p.21). Most philosophers had considered that philosophy is a knowledge, differences appear either concerning its object( first principles, the absolute, the universal etc.) or its method (by concepts to Kant) or its faculty(reason, senses etc). But, is philosophy limited just to a form of contemplative knowledge disinterested from a practical or applicative point of view? Tudosescu considers that"...only in limits in which it conditionate value reedifications at the level of other forms of social conscience and, respective, modifications in the structure of the tables of cultural values, so that these to stimulate changes whith deep character in the structure and dynamics of civilizations, we can say that philosophy have an applicative character"(Tudosescu 1997, p.169).
