Any man may make a mistake; none but a fool will stick to it. Second thoughts are best as the proverb says.
[Lat., Cujusvis hominis est errare; nullius, nisi insipientis, in errore perseverae. Posteriores enim cogitationes (ut aiunt) sapientiores solent esse.]
Angels are happier than men and devils, because they are not always prying after good and evil in one another, and eating the tree of knowledge for Satan's gratification.
Don't think about why you question, simply don't stop questioning. Don't worry about what you can't answer, and don't try to explain what you can't know. Curiosity is its own reason. Aren't you in awe when you contemplate the mysteries of eternity, of life, of the marvelous structure behind reality? And this is the miracle of the human mind - to use its constructions, concepts, and formulas as tools to explain what man sees, feels and touches. Try to comprehend a little more each day. Have holy curiosity.

It is frivolous to fix pedantically the date of particular inventions. They have all been invented over and over fifty times.

Reviewing the day's lessons. Isn't it joyful? Friends come from far. Isn't it delightful? One has never been angry at other's misunderstanding. Isn't he a respectable man?
If a man lose his balance, and immerse himself in any trades or pleasures for their own sake, he may be a good wheel or pin, but he is not a cultivated man.
There's a man in the world who is never turned down, whatever he chances to stray; he gets the glad hand in the populous town, or out where the farmers makes hay; he's greeted with pleasure on deserts of sand, and deep in the aisles of the woods; wherever he goes there's a welcoming hand-he's the man who delivers the goods.
Everyone has the obligation to ponder well his own specific traits of character. He must also regulate them adequately and not wonder whether someone else's traits might suit him better. The more definitely his own a man's character is, the better it fits him.
