Quote by Francois de La Rochefoucauld
Being a blockhead is sometimes the best security against being cheated by a man of wit.
Summary
This quote suggests that being perceived as foolish or unintelligent ("blockhead") can actually protect someone from being tricked or taken advantage of by someone who is clever or manipulative ("man of wit"). By appearing naive or simple-minded, a person may obsure their true level of intellect and make it more difficult for others to deceive or manipulate them. In essence, embracing one's perceived foolishness can be a strategic defense mechanism in dealing with cunning individuals.
