Man vs Animal-What makes us so different? I ask not because I know, or even have a strong opinion that there really is anything, but because I have heard some weird ideas. Such as the ability to create and appreciate art, or having morality, or a social structure... Do those things really make man "superior"? Aren't there examples of animals which have these traits? For the future-Man vs Machine. Someone at some point is going to make a machine which is independent and "sentient". Someone, of course, will want to prevent it from having "rights". What defines something as having a right to such rights? Where is this line between man and sentient machine?
