Man is affected not by events but by the view he takes of them. Epictetus (55 AD – 135 AD)
Just had to use this from the Wikipedia entry about our slave/philospher and his affect on the world:
The philosophy of Epictetus is well known in the American military through the writings and example of James Stockdale, an American fighter pilot who was shot down over North Vietnam, became a prisoner of war during the Vietnam War, and later a vice presidential candidate. In Courage under Fire: Testing Epictetus’s Doctrines in a Laboratory of Human Behavior (1993), Stockdale credits Epictetus with helping him endure seven and a half years in a North Vietnamese military prison—including torture—and four years in solitary confinement.
In his conclusion, Stockdale quoted Epictetus as saying, “The emotions of grief, pity, and even affection are well-known disturbers of the soul. Grief is the most offensive; Epictetus considered the suffering of grief an act of evil. It is a willful act, going against the will of God to have all men share happiness”.
