In the Nicomachean Ethics, written in 350 B.C.E., Aristotle stated that happiness is the only thing that humans desire for its own sake. He observed that men sought riches not for the sake of being rich, but to be happy. Those who sought fame desired it not to be famous, but because they believed fame would bring them happiness. Aristotle argued that humans seek everything else such as; fish, bread, and children. Many ethicists make arguments for how humans should behave, either individually or collectively, based on the resulting happiness of such behavior. Utilitarians, such as John Stuart Mill and Jeremy Bentham, advocated the greatest happiness principle as a guide for ethical behavior.
States associated with happiness -being, delight, health, safety, contentment, and love. Contrasting states include suffering, depression, grief, anxiety, and pain. Happiness is often associated with the presence of favorable circumstances such as a supportive family life, a loving marriage, and economic stability. Unfavorable circumstances, such as abusive relationships, accidents, loss of employment, and conflicts, diminish the amount of happiness a person experiences. However, according to several ancient and modern thinkers, happiness is influenced by the attitude and perspective taken on such circumstances.
