WHEN thou art offended with any man's transgression, presently reflect upon thyself, and consider what thou thyself art guilty of in the same kind.
MARCUS AURELIUS. MEDITATIONS. Book x. 30.
WHENSOEVER any man doth trespass against thee, presently consider with thyself what it was that he did suppose to be good, what to be evil, when he did trespass. For this when thou knowest, thou wilt pity him; thou wilt have no occasion either to wonder, or to be angry. For either thou thyself dost yet live in that error and ignorance, as that thou dost suppose either that very thing that he doth, or some other like worldly thing, to be good; and so thou art bound to pardon him if he have done that which thou in the like case wouldst have done thyself. Or if so be that thou dost not any more suppose the same things to be good or evil, that he doth; how canst thou but be gentle unto him that is in an error?
