Francis Crick, a nobel prize winner for physiology and medicine, is famous with his astonishing hypothesis: you, your joys and your sorrows, your memories an your ambitions, your sense of identity and free will were in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules, in short, you are nothing but a pack of neuros.
Any atheist should accept this view without doubt which make this hypothesis more astonishing than ever to most chinese people. On the other hand, being a person who is increasingly becoming one of the agnostics, I believe that besides a pack of neuros and their associated molecules, there are some other mysterious substance combined to make up a human being.
