Irreligious organizations promote the view that moral standards should be based solely on naturalistic considerations, without reference to supernatural concepts (such as God or an afterlife), any desire to do good for a reward after death, or any fear of punishment for not believing in life after death.
Individuals and organizations sharing these views, identify themselves by a variety of terms, including, bright, freethinker, naturalist, rationalist, or skeptic.[1][2] Despite the use of these various terms, the organizations listed here have goals in common. Note that, while most of these organizations and their members consider themselves irreligious, there are certain exceptions (Ethical Culture, for example).
In some jurisdictions, a provincial or national humanist society may confer upon Humanist officiants the ability to conduct memorial services, child naming ceremonies or officiate marriages – tasks which would be carried out by clergy in most organized religions.[3][4][5]
