"Evolution is promoted by its practitioners as more than mere science. Evolution is promulgated as an ideology, a secular religion—a full-fledged alternative to Christianity, with meaning and morality. . . . Evolution is a religion. This was true of evolution in the beginning, and it is true of evolution still today."
Michael Ruse, darwinist philosopher
I have quotes from Adolph Hitler saying he's doing God's work. Only a creationist thinks quoting is a trump card. Scientists look to the evidence, philosophy be damned.
So, what does our history tell us? Three things. First, if the claim is that all contemporary evolutionism is merely an excuse to promote moral and societal norms, this is simply false. Today's professional evolutionism is no more a secular religion than is industrial chemistry. Second, there is indeed a thriving area of more popular evolutionism, where evolution is used to underpin claims about the nature of the universe, the meaning of it all for us humans, and the way we should behave. I am not saying that this area is all bad or that it should be stamped out. I am all in favor of saving the rainforests. I am saying that this popular evolutionism--often an alternative to religion--exists. Third, we who cherish science should be careful to distinguish when we are doing science and when we are extrapolating from it, particularly when we are teaching our students. If it is science that is to be taught, then teach science and nothing more. Leave the other discussions for a more appropriate time.
