François duc de La Rochefoucauld

—We are deceived if we think that mind and judgment are two different matters: judgment is but the extent of the light of the mind. This light penetrates to the bottom of matters; it remarks all that can be remarked, and perceives what appears imperceptible. Therefore we must agree that it is the extent of the light in the mind that produces all the effects which we attribute to judgment.

Nothing is less sincere than the way of asking and giving advice. The person asking seems to pay deference to the opinion of his friend, while thinking in reality of making his friend approve his opinion and be responsible for his conduct. The person giving the advice returns the confidence placed in him by eager and disinterested zeal, in doing which he is usually guided only by his own interest or reputation.
["I have often thought how ill-natured a maxim it was which on many occasions I have heard from people of good understanding, ‘That as to what related to private conduct no one was ever the better for advice.' But upon further examination I have resolved with myself that the maxim might be admitted without any violent prejudice to mankind. For in the manner advice was generally given there was no reason I thought to wonder it should be so ill received, something there was which strangely inverted the case, and made the giver to be the only gainer. For by what I could observe in many occurrences of our lives, that which we called giving advice was properly taking an occasion to show our own wisdom at another's expense. On the other side to be instructed or to receive advice on the terms usually prescribed to us was little better than tamely to afford another the occasion of raising himself a character from our defects."—
