This paper analyses the tension between the double focus on critique and alterity within decolonial discourses. We argue that an excess of critical thinking could lead to scepticism, whereas an overemphasis on alterity could result in dogmatism. Consequently, since both approaches end up obstructing epistemic decolonization, we argue that it is necessary to strike a balance between critique and alterity; a balance that does not resolve the tension, but seeks to reveal its underlying relation. The first section locates decolonial theory within the framework of critical theory. We highlight how Quijano, Dussel and Mignolo invoke the critical tradition, whilst simultaneously claiming that a radical departure from it is necessary. Turning more explicitly to Dussel in Section 2, we explain Dussel’s analectics as a method to localize discourses, in which globally excluded perspectives are foregrounded. In the third section, we defend Dussel’s universalism and rationalism against criticisms from Castro-Gómez and Vallega by interpreting him as a relational thinker. Ultimately, the paper concludes that the success of epistemic decolonization hinges on its ability to reconcile classic notions of universality and rationality in a manner that avoids dogmatism and scepticism, namely by a continual grounding of philosophical discourse in material life.
