This early modern view has some connections with Hasker’s substance emergent dualism (1999). Indeed, Hasker states that the mind is a substance emerging at one time from neurons and that consciousness has causal powers which effects cannot be explained by physical neurons. An emergent unified self-existing entity emerges from the brain on which it acts upon. For its proponents, Hasker’s view explains what Descartes’s dualism fails to explain, especially why the mind regularly interacts with one and only one body. After questioning the notion of emergence, the author argues that the theory of emergent creationist substance dualism that she attributes to Descartes is a more appropriate alternative because it faces fewer problems than its rivals. This monograph is valuable for anyone interested in the history of early modern philosophy and contemporary philosophy of mind.
