Prudence is a duty which we owe ourselves, and if we will be so much our own enemies as to neglect it, we are not to wonder if the world is deficient in discharging their duty to us; for when a man lays the foundation of his own ruin, others too often are apt to build upon it.
Henry FieldingThere is a sort of knowledge beyond the power of learning to bestow, and this is to be had in conversation; so necessary is this to the understanding the characters of men, that none are more ignorant of them than those learned pedants whose lives have been entirely consumed in colleges and among books; for however exquisitely human nature may have been described by writers the true practical system can be learned only in the world.
