We get our morals from books. I didn't get mine from books, but I know that morals do come from books- theoretically at least.

The past does not repeat itself, but it rhymes.

We catched fish, and talked, and we took a swim now and then to keep off sleepiness. It was kind of solemn, drifting down the big still river, laying on our backs looking up at the stars, and we didn’t ever feel like talking loud, and it warn’t often that we laughed, only a kind of low chuckle. We had mighty good weather, as a general thing, and nothing ever happened to us at all, that night, nor the next, nor the next.

The more things are forbidden, the more popular they become.

There is no such thing as a new idea. It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope. We give them a turn and they make new and curious combinations. We keep on turning and making new combinations indefinitely; but they are the same old pieces of colored glass that have been in use through all the ages.

Your actions speak so much louder than words.

The Bible is full of interest. It has noble poetry in it; and some clever fables; and some blood-drenched history; and some good morals; and a wealth of obscenity; and upwards of a thousand lies. This Bible is built mainly out of fragments of older Bibles that had their day and crumbled to ruin. So it noticeably lacks in originality, necessarily. Its three or four most imposing and impressive events all happened in earlier Bibles; there are only two new things in it: hell, for one, and that singular heaven I have told you about.
