What indicates that Descartes might have abandoned dualism according to some interpretations?

The belief in the pineal gland's role in movement is significant because it represents Descartes' attempt to find a physical basis for the interaction between the mind and body. Descartes proposed that the pineal gland was the "seat of the soul," where the immaterial mind could influence the physical body. This idea of a specific physical site for interaction implies a more integrated relationship between mind and body than traditional dualism typically suggests, which posits a strict separation between the two.

This reliance on the pineal gland as an interaction point suggests a shift toward a more unified understanding of mental and physical processes, which challenges pure dualistic interpretations. Dualism typically emphasizes the distinctness of mental and physical substances without proposing a mechanism for their interaction, while Descartes' views indicate a potential intertwining of these realms. Therefore, his focus on the pineal gland points to a complexity in his stance that can be interpreted as a movement away from classic dualism.

In contrast, rejecting materialist perspectives, accepting free will, or emphasizing emotional experiences do not directly indicate a departure from dualism. Rejection of materialism maintains a distinction between the physical and mental, while acceptance of free will and emphasis on emotions can still align with dualistic thought
