How can we define ourselves?

When we speak in the first person we say "I ...". But who is this 'I'? Are we to be identified with our physical bodies? With our minds? Are we a collection of different things? Do we exist outside of our bodies?

Points to consider:

• When a chocolate bar is placed in front of us and we say "one part of me wants it, while another tells me I have to stay healthy" what do we mean?
• Apply electrical shocks to the brain and personality can be altered.
• A person who suffers brain damage is not the same. In severe cases they may resemble nothing of their former characteristics, being more like a living body without all their previously 'normal' characteristics.
