New:I read about a very interesting philosophical paradox. If a ship has all its components replaced, do u think it remains the same ship or becomes another new ship? Actually it discusses abou how to define identity--- what makes me "me". Am i still the same person if i lose memory or lose one arm? I never thought about it before. I think my conclusion is that it becomes a new ship which means every second I'm another me. I'm changing all the time. WOW.
