You know what crazy is? Crazy is majority rules. Take germs, for example. Uh-huh. Eighteenth century: no such thing, nada, nothing. No one ever imagined such a thing. No sane person. Along comes this doctor, uh, Semmelweis, Semmelweis. Semmelweis comes along. He's trying to convince people, other doctors mainly, that's there's these teeny tiny invisible bad things called germs that get into your body and make you sick. He's trying to get doctors to wash their hands. What is this guy? Crazy? Teeny, tiny, invisible? What do they call it? Uh-uh, germs? Huh? What? Now, up to the 20th century — last week, as a matter of fact, before I got dragged into this hellhole — I go in to order a burger at this fast-food joint, and the guy drops it on the floor. James, he picks it up, he wipes it off, he hands it to me like it's all OK. "What about the germs?" I say. He says "I don't believe in germs. Germs is a plot made up so they could sell disinfectants and soaps." Now he's crazy, right? See? Ah! Ah!
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age.
