What is the nature of the psychological world according to Descartes?

Descartes posited a dualistic view of the mind and body, famously articulating the distinction between the immaterial mind, which encompasses thoughts and consciousness, and the material body, which is physical and subject to the laws of nature. In his philosophical approach, particularly in works like "Meditations on First Philosophy," he argued that the mind is a non-physical substance that cannot be fully explained by physical phenomena. This perspective highlights the immaterial nature of psychological processes as separate from the physical body, which aligns with the choice indicating that the psychological world is immaterial and ethereal. Thus, this distinction emphasizes Descartes' contribution to understanding the nature of consciousness and its relationship to the physical world, affirming the importance of the non-material aspects of psychology in his philosophy.
