What do people mean when they use the phrase blind faith?
Like many words, this phrase will surely mean different things to different people. I define blind faith as the unquestioning acceptance of statements spoken by an authority, and in my definition, such faith is accompanied by a lack of critical thinking. Going further, blind faith refuses to apply critical thinking even in the face of solid evidence suggesting that the statements being accepted in blind faith may actually be incorrect.
One anti-religious criticism we tend to hear ad nauseum is that religion is based on blind faith. To a certain extent, such can be true, but sweeping generalizations like this always portray a one-sided view of things. There are many, many religious people who do not base their beliefs on blind faith, and just as many irreligious people who do. Humans accept all sorts of statements on blind faith every day, and blind faith is by no means an exclusively religious error.
So without defending or attacking those who accept their religious beliefs on blind faith, I'd like to discuss an area where blind faith and rejection of science are arguably stronger motivators for belief than in religion: and that area is medicine.
