“ a man cannot lie with his neighbour's wife, but it detects him: 'tis a blushing shame-faced spirit that mutinies in a man's bosom; it fills a man full of obstacles: it made me once restore a purse of gold that by chance I found; it beggars any man that keeps it: it is turned out of towns and cities for a dangerous thing ”
 William Shakespeare, Richard III (1597). copy citation

“there's few or none will entertain it. FIRST MURDERER What if it come to thee again? SECOND MURDERER I'll not meddle with it,—it makes a man coward; a man cannot steal, but it accuseth him; a man cannot swear, but it checks him; a man cannot lie with his neighbour's wife, but it detects him: 'tis a blushing shame-faced spirit that mutinies in a man's bosom; it fills a man full of obstacles: it made me once restore a purse of gold that by chance I found; it beggars any man that keeps it: it is turned out of towns and cities for a dangerous thing; and every man that means to live well endeavours to trust to himself and live without it. FIRST MURDERER Zounds,'tis even now at my elbow, persuading me not to kill the duke. SECOND MURDERER Take the devil in thy mind, and believe him not;” source
