“Folly consists not in committing Folly, but in being incapable of concealing it. All men make mistakes, but the wise conceal the blunders they have made, while fools make them public. Reputation depends more on what is hidden than on what is seen. If you can’t be good, be careful.”

“A wise man gets more use from his enemies than a fool from his friends.”

“Keep the extent of your abilities unknown.The wise man does not allow his knowledge and abilities to be sounded to the bottom, if he desires to be honored at all. He allows you to know them but not to comprehend them. No one must know the extent of his abilities, lest he be disappointed. No one ever has an opportunity of fathoming him entirely. For guesses and doubts about the extent of his talents arouse more veneration than accurate knowledge of them, be they ever so great.”

“Do not enter where too much is anticipated. It is the misfortune of the over-celebrated that they cannot measure up to excessive expectations. The actual can never attain the imagined: for to think perfection is easy, but to embody it is most difficult. The imagination weds the wish, and together they always conjure up more than reality can furnish. For however great may be a person's virtues, the will never measure up to what was imagined. When people see themselves cheated in their extravagant anticipations, they turn more quickly to disparagement than to praise. Hope is a great falsifier of the truth; the the intelligence put her right by seeing to it that the fruit is superior to its appetite. You will make a better exit when the actual transcends the imagined, and is more than was expected.”

“Better mad with the rest of the world than wise alone.”

“A person of your century: Great persons are of their time. Not all were born into a period worthy of them, and many so born failed to benefit by it. Some merited a better century, for all that is good does not always triumph. Fashions have their periods and even the greatest virtues, their styles. But the philosopher, being ageless, has one advantage: Should this not prove the right century, many to follow will.”

“One should cultivate good habits of memory, for it is capable of making existence a Paradise or an Inferno.”
