The Purpose of Happiness

"The question 'What is true happiness?' can only be finally answered on the basis of the answer to another question: What is the chief end of man? But the age of reason had banished teleology from its way of understanding the world, and so 'happiness' had no definition except what each autonomous individual might give it. Each individual has the right not only to pursue happiness but to define it as he wishes."
