Who loves or pursues or desires
to obtain pain of itself, because it
can procure great pleasure.

To taken a trivial example, which of
us ever undertakes it laborious
physical exercise works.

Which is the same saying through
shrinking from toil and pains. These
cases are perfectly simple & easy
to distinguish. In a free hour, when
our power oft we like best.

Pleasure is to be welcomed every
pain avoided. But in certain claims of
duty or the obligations.
