This article aims at reconstruction of crucial for pedagogy of emancipation notions associated with colonisation and decolonisation. This objective includes both literally and metaphor meanings of colonisation and decolonisation used by P. Freire in his philosophy of education. Thus I will present modified by P. Freire conception of closed society as a relic of colonial society and I will also present his notion of colonisation and decolonisation of minds as an objective action for basic literacy during decolonisation processes in Africa in the seventies. The main reason of such purpose of this text is that colonisation is the crucial point and the main cause of emancipation in Freire’s conception of social movements in general and popular education in particular. On the other hand decolonisation is an archetypal form of emancipation, thus taking into account present social inequalities theory of P. Freire is still totally valid.
