Rowlands in his book ‘A New Science of the Mind’ provides the basis of categorising non-cartesian understanding of cognition (Rowlands‚ 2010). Embodied‚ extended‚ emergent and extended cognitive science as an alternative research paradigm has been in the rise in the last few decades. Various empirical evidence and theoretical understanding of this paradigm has shown the validity for each of the four non-cartesian approach to cognition.
