Fin Keegan

Every good human quality is related to a bad one into which it threatens to pass over; and every bad quality is similarly related to a good one. The reason we so often misunderstand people is that when we first make their acquaintance we mistake their bad qualities for the related good one, or vice versa: thus a prudent man will seem cowardly, a thrifty one avaricious; or a spendthrift will seem liberal, a boor frank and straightforward, an impudent fellow full of noble self-confidence, and so on.
