The Evolution of Moral Cognition

<p>Many modern approaches to the evolution of mind have claimed that the fundamental drivers of our cognitive capacities and cultures are genetically specified psychological adaptations, which evolved in response to evolutionary pressures deep within our lineage's history. Many of our cognitive capacities are innate. Recent approaches to moral cognition have similarly argued that moral cognition is innate. In this thesis, I argue that even though our capacity for moral cognising is an adaptation, it is a learned adaptation. Moral cognition is not innate. In arguing this thesis I will question many of the assumptions of traditional cognitive science and evolutionary approaches to the mind. By incorporating theory and evidence from cognitive science and the philosophy of mind, I apply the explanatory frameworks of embodied and extended cognition to the domain of morality: moral cognition is both embodied and extended cognition. This places particular importance on the role of our bodies and world in the fundamental structuring and scaffolding of the development and execution of moral cognition. Putting this in an evolutionary framework, I develop a dual inheritance model of the non-nativist evolution of moral cognition focusing on the roles of niche construction, biased learning and active learning in the transfer of moral phenotypes between generations. Morality is a learned adaptation that evolved through the dynamic and reciprocal interaction between genes and culture.</p>
