“Now if you do have a perception that any conceivable consideration may be utterly invalidated by some other consideration which you do not know, and if you are reminded of this perception constantly by the fact that things exist, certain modifications take place in the way you feel about things. These modifications have not taken place in the psychology of most people.”

Context: You reason well, and your wit is bold, but you are too prejudiced. You do not let your eyes see nor your ears hear, and that which is outside your daily life is not of account to you. Do you not think that there are things which you cannot understand, and yet which are, that some people see things that others cannot? But there are things old and new which must not be contemplated by men's eyes, because they know, or think they know, some things which other men have told them. Ah, it is the fault of our science that it wants to explain all, and if it explain not, then it says there is nothing to explain. But yet we see around us every day the growth of new beliefs, which think themselves new, and which are yet but the old, which pretend to be young, like the fine ladies at the opera.
