"Consciousness is what makes the mind-body problem really intractable"

This quote by Thomas Nagel is describing the mind-body problem, which is the philosophical concern of how the body and mind relate. Nagel is suggesting that awareness is what makes this problem so challenging to resolve. Consciousness is the awareness of one's own thoughts, feelings, and experiences, and it is something that is distinct to each individual. It is hard to discuss how the body and mind are related when awareness is involved, as it is not something that can be easily measured or measured. Nagel's quote suggests that the mind-body issue is an intricate concern that is challenging to fix due to the existence of consciousness. It recommends that awareness is a crucial factor in understanding the relationship in between the body and mind, and that it is a major barrier in finding an option to the mind-body issue.
