For vice is weakness, and the artful know
Their power increases as the passions grow;
If indolent the pupil, hard their task;
Such minds will ever for amusement ask;
And great the labour! for a man to choose
Objects for one whom nothing can amuse;
For ere those objects can the soul delight,
They must to joy the soul herself excite;
Therefore it is, this patient, watchful kind
With gentle friction stir the drowsy mind:
