The aim of this essay is to establish that critical rationalism currently exists in an incoherent state. This is demonstrated through an analysis of the discourse's key fields (its metaphysics, metascience and politics), their constituents and conditions of co-existence. Looking at each field, the study shows that critical rationalism is beset by issues that undermine its cohesion. These range from contradictory proposals, through deficiencies in argument to inadequate conceptualisation. In the light of this assessment, it is suggested that greater coherence could be achieved by sacrificing its metaphysics and politics, and focusing on the regeneration of the metascience.
