In order to judge of the inside of others, study your own; for men in general are very much alike; and though one has one prevailing passion, and another has another, yet their operations are much the same; and whatever engages or disgusts, pleases or offends you, in others, will, mutatis mutandis, engage, disgust, please, or offend others, in you.
