The premise of this article is that there is need for a critical review of the principles that run through the historic trajectory of Social Work and establish a continuous line between its conservative base and the tendency that seeks to break with this, and even influence it. A critical analysis is conducted of the influence of pragmatism in Social Work that, as an ideal representation of the immediacy of the bourgeois world, would influence the profession from a practical, professional, theoretical and ideological-political perspective, constituting a challenge to be faced by all segments in the category. The paper concludes by affirming that without a critical reading of the fundaments of pragmatism, it is not possible to advance in the suitable appropriation of Marxist social theory, given that there has been an "invasion of pragmatism in Marxism".
