“Most fortunately it happens, that since reason is incapable of dispelling these clouds, nature herself suffices to that purpose, and cures me of this philosophical melancholy and delirium, either by relaxing this bent of mind, or by some avocation, and lively impression of my senses, which obliterate all these chimeras. I dine, I play a game of backgammon, I converse, and am merry with my friends; and when after three or four hours' amusement, I would return to these speculations, they appear so cold, and strain'd, and ridiculous, that I cannot find in my heart to enter into them any farther.”
― David Hume, A Treatise of Human Nature

“He had discovered a great law of human action, without knowing it -- namely, that in order to make a man or a boy covet a thing, it is only necessary to make the thing difficult to attain. If he had been a great and wise philosopher, like the writer of this book, he would now have comprehended that Work consists of whatever a body is obliged to do, and that Play consists of whatever a body is not obliged to do.”
― Mark Twain , The Adventures of Tom Sawyer

“To fear death, gentlemen, is no other than to think oneself wise when one is not, to think one knows what one does not know.  No one knows whether death may not be the greatest of all blessings for a man, yet men fear it as if they knew that it is the greatest of evils.  And surely it is the most blameworthy ignorance to believe that one knows what one does not know.  It is perhaps on this point and in this respect, gentlemen, that I differ from the majority of men, and if I were to claim that I am wiser than anyone in anything, it would be in this, that, as I have no adequate knowledge of things in the underworld, so I do not think I have.  I do know, however, that it is wicked and shameful to do wrong, to disobey one's superior, be he god or man.  I shall never fear or avoid things of which I do not know, whether they may not be good rather than things that I know to be bad.”
― Socrates

Khuda bande se khud pooche bata teri raza kya hai.”
