- FOOL, n. A person who pervades the domain of intellectual speculation and diffuses himself through the channels of moral activity. He is omnific, omniform, omnipercipient, omniscience, omnipotent. He it was who invented letters, printing, the railroad, the steamboat, the telegraph, the platitude and the circle of the sciences. He created patriotism and taught the nations war—founded theology, philosophy, law, medicine and Chicago. He established monarchical and republican government. He is from everlasting to everlasting—such as creation's dawn beheld he fooleth now. In the morning of time he sang upon primitive hills, and in the noonday of existence headed the procession of being. His grandmotherly hand was warmly tucked-in the set sun of civilization, and in the twilight he prepares Man's evening meal of milk-and-morality and turns down the covers of the universal grave. And after the rest of us shall have retired for the night of eternal oblivion he will sit up to write a history of human civilization.

- You will be amused when you see that I have more than once deceived without the slightest qualm of conscience, both knaves and fools. As to the deceit perpetrated upon women, let it pass, for, when love is in the way, men and women as a general rule dupe each other. But on the score of fools it is a very different matter. I always feel the greatest bliss when I recollect those I have caught in my snares, for they generally are insolent, and so self-conceited that they challenge wit. We avenge intellect when we dupe a fool, and it is a victory not to be despised for a fool is covered with steel and it is often very hard to find his vulnerable part. In fact, to gull a fool seems to me an exploit worthy of a witty man.
- Giacomo Casanova, Memoirs of J. Casanova de Seingalt (1894).

- A wise man changes his mind sometimes, but a fool never. To change your mind is the best evidence you have one. The last redoubt holding out for me was the year-day principle (on which I had written a defense in 1972 for the Southern Publishing Association Daniel volume which was published in 1978). This collapsed when I handled hundreds of books of commentary on Revelation in the Library of Congress stacks and found that the respective authors had in many cases suggested dates that seemed appropriate for their own time but ridiculous later. It became clear that we, as Adventists, had done the same as our predecessors.

I thought I was leading you away from everyone else..." And then he died.
