“Don't pass it by--the immediate, the real, the only, the yours.”

as quoted by Ray Kurzweil, The Age of Spiritual Machines: When Computers Exceed Human Intelligence (2000)

Catch-22 (1961)
Context: There was only one catch and that was Catch-22, which specified that a concern for one's safety in the face of dangers that were real and immediate was the process of a rational mind. Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. Yossarian was moved very deeply by the absolute simplicity of this clause of Catch-22 and let out a respectful whistle. "That's some catch, that Catch-22," he observed. "It's the best there is," Doc Daneeka agreed.

1900s, Getting Married (1908)
Context: Religion is a great force — the only real motive force in the world; but what you fellows don't understand is that you must get at a man through his own religion and not through yours. Instead of facing that fact, you persist in trying to convert all men to your own little sect, so that you can use it against them afterwards. You are all missionaries and proselytizers trying to uproot the native religion from your neighbor's flowerbeds and plant your own in its place. You would rather let a child perish in ignorance than have it taught by a rival sectary. You can talk to me of the quintessential equality of coal merchants and British officers; and yet you can't see the quintessential equality of all the religions.
