The current study deals with Winnicott`s thought, searching in it another conception of the individual/society relationship, different from the one that prevails today in the social scenario. His idea of a spontaneous vitality, and the necessary conditions for its full expression, opposes the biopower mechanisms described by Foucault that take life in a way to maximize its economic use. At the same time, his assumption of a subjectivity that can only emerge and differentiate itself supported by a consistent environment opposes the helplessness and vulnerability experience described by Castel as characteristic of the contemporaneous man. Besides that, Winnicott´s notion of a capacity of concern with the other that does not depend on coercion and controls, but on an internalized careful environment, seems very close to Foucault latest analysis that deals with the concern of self in antiquity. In such analysis, the Greek-Roman ethics is understood as the expression of freedom, being recovered to the present in the form of friendship. Both Winninicott and Foucault support an idea of a potential openess of the individual to the other, but the former is the one who, clearly recognizing the needs and natural trends of creative life, without closing it in normative standards, allows us to criticize the new ideal of a subject completely open to the external demands.
