Step-by-step explanation:
The mind-body problem is the problem of understanding the relationship between the mind and the body. It is the problem of explaining how mental events, such as thoughts and feelings, are related to physical events, such as brain activity. There are different theories that attempt to explain this relationship, including dualism, which posits that the mind and body are two separate substances that interact or are coordinated in some way; epiphenomenalism, which suggests that the body acts on the mind but the mind does not act on the body; and double aspect theory, which proposes that there is one substance with two aspects, the mind and the body.
