Good Lord, what is man! for as simple he looks, Do but try to develop his books and his crooks, With his depths and his shallows, his good and his evil, All in all, he's a problem must puzzle the devil.
Robert BurnsBut Mousie, thou art no thy lane In proving foresight may be vain The best-laid schemes o' mice an' men Gang aft agley An' lea'e us nought but grief an' pain For promis'd joy!
Robert Burns
