“O Opportunity, thy guilt is great! ’Tis thou that execut’st the traitor’s treason; Thou sets the wolf where he the lamb may get; Whoever plots the sin, thou ’point’st the season. ’Tis thou that spurn’st at right, at law, at reason; And in thy shady cell, where none may spy him, Sits Sin, to seize the souls that wander by him.
