When Knaves betray each other, one can scarce be blamed or the other pitied.
Who has deceived thee as oft as thyself.
Hast thou virtue? acquire also the graces and beauties of virtue.
A new truth is a truth, an old error is an error.
A father's a treasure; a brother's a comfort; a friend is both.
Rich widows are the only secondhand goods that sell at first-class prices.
