Radical views on cognition are generally defined by a cluster of features including non-representationalism and vehicle-externalism. In this paper, I concentrate on the way radical views on cognition define themselves as revolutionary theories in cognitive science. These theories often use the Kuhnian concepts of “paradigm” and “paradigm shift” for describing their ambitions and the current situation in cognitive science. I examine whether the use of Kuhn’s theory of science is appropriate here. There might be good reasons to think that cognitive science is in a situation of foundational crisis, but that does not entail that the classical paradigm (computationalism) is currently displaced to the benefit of a new paradigm. Larry Laudan’s theory of research traditions is more enlightening than Kuhn’s theory for describing the scope and ambitions of radical views on cognition, and their relations with an anti-intellectualist tradition in philosophy.

Optimising the 4E (embodied–embedded–extended–enactive) revolution in cognitive science arguably requires the rejection of two guiding commitments made by orthodox thinking in the field, namely that the material realisers of cognitive states and processes are located entirely inside the head (internalism), and that intelligent thought and action are to be explained in terms of the building and manipulation of content-bearing representations (representationalism). In other words, the full- strength 4E revolution would be secured only by a position that delivered externalism plus antirepresentationalism. I argue that one view in 4E space – extended functionalism – is appropriately poised to deliver externalism but not antirepresentationalism. By contrast, in the case of a competing 4E view – radical enactivism – even if that view can deliver antirepresentationalism, its pivotal notion of extensiveness falls short of establishing externalism. These conclusions are justified via an examination of, and by responding critically to, certain key arguments offered in support of their view (and against extended functionalism) by the radical enactivists.
