What philosophical stance claims that the mind/spirit is real but immaterial, while matter is a creation of the mind?

The philosophical stance that asserts the mind or spirit is real and immaterial, and that matter is a creation of the mind, is idealism. Idealism posits that reality is fundamentally mental and that the material world is a manifestation or creation of the mind's perceptions. This view suggests that what we perceive as physical is dependent on our mental experiences, emphasizing the primacy of consciousness over the material realm.

In contrast, materialism, which suggests that only physical matter is real and that everything can be explained through physical processes, directly opposes the idea of an immaterial mind. Substance dualism holds that both the mind and body exist as separate but interacting substances, which conflicts with the notion that matter is simply a creation of the mind. Property dualism accepts both physical and mental properties but does not assert that matter derives from mental constructs. Therefore, idealism distinctly aligns with the premise that the mind/spirit is the foundation of reality, making it the correct philosophical stance in this context.
