"Real" knowledge is that constant, never-ending search for the truth in all disciplines, free from the fetters of the prejudice and bias of religion, or any philosophy that rejects the scientific process.
Not all religions reject science. You are greatly over generalizing. The "prejudice and bias" towards science comes from the ultra-conservatives who are too scared to admit they, and thier books, might be or are wrong.
Example; A school bans the Al Gore documentary on Global Warming because a parent complained because it doesn't show the "biblical" viewpoint that "in the end, the sun will burn everything up." I won't argue that holding such viewpoints is unhealthy, destructive, and frightening.
ONTOH, thier are many religious people who do accept science theories. Some more than others, but just because your religious, doesn't mean you reject all of science.
