Secular humanism is a philosophy, belief system or life stance that embraces human reason, secular ethics, and philosophical naturalism while specifically rejecting religious dogma, supernaturalism, and superstition as the basis of morality and decision making. Secular humanism posits that human beings are capable of being ethical and moral without religion or belief in a deity. It does not, however, assume that humans are either inherently good or evil, nor does it present humans as being superior to nature. Rather, the humanist life stance emphasizes the unique responsibility facing humanity and the ethical consequences of human decisions. Fundamental to the concept of secular humanism is the strongly held viewpoint that ideology—be it religious or political—must be thoroughly examined by each individual and not simply accepted or rejected on faith. Along with this, an essential part of secular humanism is a continually adapting search for truth, primarily through science and philosophy. Many secular humanists derive their moral codes from a philosophy of utilitarianism, ethical naturalism, or evolutionary ethics, and some advocate a science of morality. Humanists International, founded by Julian Huxley and Jaap van Praag, is the world union of more than one hundred humanist, rationalist, irreligious, atheist, Bright, secular, Ethical Culture, and freethought organizations in more than 40 countries. The "Happy Human" is recognized as the official symbol of humanism internationally, used by secular humanist organizations in every part of the world. The meaning of the phrase secular humanism has evolved over time. The phrase has been used since at least the 1930s by Anglican priests, and in 1943, the then Archbishop of Canterbury, William Temple, was reported as warning that the "Christian tradition... was in danger of being undermined by a 'Secular Humanism' which hoped to retain Christian values without Christian faith.
