The highest goal of human life is the enhancement of pleasure and the reduction of pain. Life should be organized to serve the pursuit of happiness. There is no ethical purpose higher than facilitating this pursuit for oneself and one's fellow creatures. All the other claims--the service of the state, the glorification of the gods or the ruler, the arduous pursuit of virtue through self-sacrifice--are secondary, misguided, or fraudulent. The militarism and the taste for violent sports that characterized his own culture seemed to Lucretius in the deepest sense perverse and unnatural. Man's natural needs are simple. A failure to recognize the boundaries of these needs leads human beings to a vain and fruitless struggle for more and more.
