Jonathan Swift Quote

The motives of the best actions will not bear too strict an inquiry. It is allowed that the cause of most actions, good or bad, may be resolved into the love of ourselves; but the self-love of some men inclines them to please others, and the self-love of others is wholly employed in pleasing themselves. This makes the great distinction between virtue and vice.
