Mind-Body Problem

Are the mind and the body separate entities, or one and the same thing? If they are separate, how do they relate? If they are one 'substance', is this substance mental or purely physical in nature? The 'mind-body problem', the difficulty of understanding how mind and body (or brain) relate, has fascinated philosophers for centuries and has profound implications for how we think about and treat other human beings. http://humanjourney.org.uk/articles/the-mind-body-problem/
