Secular humanists

The philosophy or life stance of secular humanism (alternatively known by some adherents as Humanism, specifically with a capital H to distinguish it from other forms of humanism) embraces human reason, ethics, social justice, and philosophical naturalism while specifically rejecting religious dogma, supernaturalism, pseudoscience, and superstition as the bases of morality and decision making.

Secular humanism posits that human beings are capable of being ethical and moral without religion or a god. It does not, however, assume that humans are either inherently evil or innately good, 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 Humanists derive their moral codes from a philosophy of utilitarianism, ethical naturalism, or evolutionary ethics, and some, such as Sam Harris, advocate a science of morality.

The International Humanist and Ethical Union (IHEU) is the world union of more than one hundred Humanist, rationalist, irreligious, atheistic, Bright, secular, Ethical Culture, and freethought organizations in more than 40 countries. The "Happy Human" is the official symbol of the IHEU as well as being regarded as a universally recognised symbol for those who call themselves Humanists. Secular humanist organizations are found in all parts of the world. Those who call themselves humanists are estimated to number between four and five million people worldwide.
