"... But I'm annoying you to no purpose with my arguments. A person whose house is only open on the west can't see the sun rise at dawn; it's only seen when the sun sets at dusk. If one tries to compare the color and appearance of the two, one will go on arguing forever... ...The fault lies not with the vision but with the closed windows. If you look out of only one opening till the day you die, you'll ever see anything new."
