Society is the true sphere of human virtue. In social, active life, difficulties will perpetually be met with; restraints of many kinds will be necessary; and studying to behave right in respect of these is a discipline of the human heart, useful to others, and improving to itself. Suffering is no duty, but where it is necessary to avoid guilt, or to do good; nor pleasure a crime, but where it strengthens the influence of bad inclinations, or lessens the generous activity of virtue.
