WHY do not you, as we pity the blind and lame, so likewise pity those who are blinded and lamed in their superior faculties ? Whoever, therefore, duly remembers that the appearance of things to the mind is the standard of every action to man : that this is either right or wrong : and, if right, he is without fault, if wrong, he himself bears the punishment ; for that one man cannot be the person deceived, and another the sufferer : will not be outrageous and angry at anyone ; will not revile, or reproach, or hate, or quarrel with anyone.
EPICTETUS. DISCOURSES. Book i. §28. ¶2
IS the cucumber bitter? set it away. Brambles are in the way? avoid them. Let this suffice. Add not presently speaking unto thyself. What serve these things for in the world? For, this, one that is acquainted with the mysteries of Nature, will laugh at thee for it ; as a Carpenter would or a Shoemaker, if meeting in either of their shops with some shavings, or small remnants of their work, thou shouldst blame them for it.
