Abstract: The ambition of “Praxis and Value” is to be “a real and positive approach”, in other words, a study based on textual analysis and theory. Starting from Yasmina Reza’s play entitled Art and from the works of Dominique de Roux and Richard Millet, the idea of value will be dealt with according to the notions of “taste”, “fortune” and “practice”, in order for this choice to lead to a meaning of the notion of “value”, which will be both complete and precise.
