<p>"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."</p>
