In reply to those who bring forward the disgraceful pleasures one
may say that these are not pleasant; if things are           to
people of vicious constitution, we must not suppose that they are also
pleasant to others than these, just as we do not reason so about the
things that are wholesome or sweet or bitter to sick people, or
ascribe whiteness to the things that seem white to those suffering
from a disease of the eye.
