This article investigates how we can reconcile conceptions of human nature with biological explanations. Therefore, it discusses essential differences between (neo) Cartesian substance dualism and (neo) Aristotelian substance monism. It argues that only the (neo) Aristotelian conception of the psuchē, as the set of potentialities the exercise of which is characteristic of the organism, is coherent. The question of how we can reconcile this conception with biological explanations is answered by discussing how it can be integrated with Tinbergen’s subdivision of (...) causal explanations into two proximate and two ultimate explanations, and with modern evolutionary theory. The use of the resulting overarching framework is illustrated by discussing its application to empirical phenomena. (shrink)

This article discusses some essential differences between the Cartesian and neo-Aristotelian conceptions of child development. It argues that we should prefer the neo-Aristotelian conception since it is capable of resolving the problems the Cartesian conception is confronted by. This is illustrated by discussing the neo-Aristotelian alternative to the Cartesian explanation of the development of volitional powers, and the neo-Aristotelian alternative to the Cartesian simulation theory and theory–theory account of the development of social cognition. The neo-Aristotelian conception is further elaborated by (...) discussing how it differs from both behaviorism and cognitive neuroscience. (shrink)
