On the other hand, we denounce with righteous
   indignation and dislike men who are so beguiled and demoralized
   by the charms of pleasure of the moment, so blinded by desire, that
   they cannot foresee the pain and trouble that are bound to ensue;
   and equal blame belongs to those who fail in their duty through
   weakness of will, which is the same as saying through shrinking
   from toil and pain. These cases are perfectly simple and easy to
   distinguish. In a free hour, when our power of choice is untrammelled
   and when nothing prevents our being able to do what we like best,
   every pleasure is to be welcomed and every pain avoided. But in
   certain circumstances and owing to the claims of duty or the obligations
   of business it will frequently occur that pleasures have to be repudiated
   and annoyances accepted. The wise man therefore always holds in these
   matters to this principle of selection: he rejects pleasures to secure
   other greater pleasures, or else he endures pains to avoid worse pains.
