The Ghost in the Machine is a famous book by Gilbert Ryle in which he attempted to dispose of belief in the mind as an independent entity. Yet if the mind is produced by the brain its activity must depend on neurological mechanisms and it cannot be responsible for its activity. All our thoughts, feelings, values and decisions must be determined and beyond "my" or "your" control for the simple reason that there is no self to do the controlling!
Your idea that we need our bodies to fulfil our aspirations implies that we are distinct from our bodies. :)
I agree. Our bodies certainly make our lives richer but the most precious aspects of our existence are intangible. How can truth, goodness, justice, freedom, beauty, friendship and love be explained mechanistically?
