At the crossroads -- To be and not to be -- In search of the great watchmaker -- The universe in a grain of sand -- Mirages of reality -- Like a bolt from the blue -- Each to his own reality -- Questions of time -- Chaos and harmony -- The virtual frontier -- Robots that think they can think? -- The grammar of the universe -- Reason and contemplation -- Beauty is in the eye of the beholder -- From meditation to action -- The monk's conclusion -- The scientist's conclusion.
