Why, all delights are vain, but that most vain Which, with pain purchased, doth inherit pain: As, painfully to pore upon a book, To seek the light of truth, which truth the while Doth falsely blind the eyesight of his look.
William Shakespeare, H. R. Woudhuysen (1998). “Love's Labour's Lost: Third Series”, p.117, Cengage Learning EMEA
