There are certainly more mysteries than knowledge and, perhaps, more ways of finding out than science. I like science because when you think of something you can check it by experiment; "yes" or "no", Nature says, and you go on from there progressively. Other wisdom has no equally certain way of separating truth from falsehood. So I have taken the easy course with easy methods.
