Chris asked:

The greatest good is pleasure and the highest evil is pain. Agree or Disagree?

============

Disagree. Panayot Butchvarov has pointed that if you take pleasure as the greatest good then you
either deny that virtue, honour and money are as good or you count them as pleasures. Neither
position is easily defensible, so Butchvarov (Skepticism in Ethics) suggests that we admit that
pleasure is a good and that virtue, honour and money are also good but not pleasures.

When we judge something to be good we don't mean pleasurable, although this is one thing that we
can mean. Pleasure can just be "nice" or "fun" and sometimes pleasure is incompatible with the moral
sense of the term good. Good is abstract and irreducible, and good is the greatest good and evil is
the greatest evil would probably be a better, more Platonic, way of trying to understand what good is.
