Philosophical Isms

Here are 234 different isms, each representing a philosophical, political or moral doctrine or a belief system. In selecting terms for the list, I have deliberately avoided any word which apply ism to a personal name, so that Marxism doesn't count although it is otherwise an ideal candidate for the list. I also excluded isms which do not refer to a specific belief system, such as impressionism (an artistic movement) or alcoholism (a disease). Despite these omissions, enough remain to leave an ism in every pot, including beliefs about proper government, God, and the nature of existence itself. Of the terms on the list that are of a religious nature, most are Christian, which is not unexpected, but I'm open to adding isms from other world religions.
