1) Aristotle's theory of happiness states that happiness is the highest good. There are many items that are good, but goods pursued for their own sake are of a higher good than goods pursued for the sake of something else.

             Animals cannot bear rights because the concept of rights is essentially human- it has force within a human world. To say an animal has rights is to apply to its wo
