“…Given this specific epistemological concern with reworking the mechanism–process conflation in those large strands of literature, it is not realist(ic) to expect my forum paper to deal with the much bigger ‘unresolvable problem’ of ontological incompatibilities in human geography identified in Whiteside (2019: 270) – the fundamental irreconcilability of this grounding in critical realism with ‘anti-realist ontologies’, such as postmodern, constructivist, non-human, behaviouralist or otherwise non-social centred philosophies of being.
