"No wise man can have a contempt for the prejudices of others; and he should even stand in a certain awe of his own, as if they were aged parents and monitors. They may in the end prove wiser than he."
"There are few things in which we deceive ourselves more than in the esteem we profess to entertain for our firends. It is little better than a piece of quackery. The truth is, we think of them as we please--that is, as they please or displease us."
"There are persons who cannot make friends. Who are they? Those who cannot be friends. It is not the want of understanding or goodnature, of entertaining or useful qualities, that you complain of: on the contrary, they have probably many points of attraction; but they have one that neutralises all these--they care nothing about you, and are neither the better nor worse for what you think of them. They manifest no joy at your approach; and when you leave them, it is with a feeling that they can do just as well without you. This is not sullenness, nor indifference, nor absence of mind; but they are intent solely on their own thoughts, and you are merely one of the subjects they exercise them upon. They live in society as in a solitude."
