I hear the religious folk bandy these words around a lot, and because of the strangeness I decided to try find out more about them. What makes me wonder about these words are the following: - Why should evolution and the theory around it have and ism or an ist? For instance I have never heard of someone who believes in the theory of gravity to be known as a Gravitationist, or that someone who believes in the germ theory of disease called a Germist. If someone disagree`s with say a field of study in the histories such as the Holocaust, they are known as a holocaust denialist. Someone who doesn't believe in the HIV theory for AIDS is normally known as an AIDS denialists. People who agree with the theories are not known as holocaustists or hivists. Why should this apply to the theory of evolution? - Lets have a look at the dictionary definition on the word: http://dictionary.reference.com/browse/evolutionist Now why is this word in the dictionary? Is it the correct usage of the word? The wikipedia article on Evolutionism gives you a much deeper insight into the history's of the word and the current usage of the word: http://en.wikipedia.org/wiki/Evolutionism I just get the feeling that the dictionary definition is inaccurate.
