The better to determine this question, let us suppose a man to be engaged in the progressive voluptuousness of the most sensual scene. Here, if ever, we may expect sensation to be triumphant. Passion is in this case in its full career. He impatiently shuts out every consideration that may disturb his enjoyment; moral views and dissuasives can no longer obtrude themselves into his mind; he resigns himself, without power of resistance, to his predominant idea. Alas, in this situation, nothing is so easy as to extinguish his sensuality! Tell him at this moment that his father is dead, that he has lost or gained a considerable sum of money, or even that his favourite horse is stolen from the meadow, and his whole passion shall be instantly annihilated: so vast is the power which a mere proposition possesses over the mind of man. So conscious are we of the precariousness of the fascination of the senses that upon such occasions we provide against the slightest interruption. If our little finger ached, we might probably immediately bid adieu to the empire of this supposed almighty power. It is said to be an experiment successfully made by sailors and persons in that class of society, to lay a wager with their comrades that the sexual intercourse shall not take place between them and their bedfellow the ensuing night, and to trust to their veracity for a confession of the event. The only means probably by which any man ever succeeds in indulging the pleasures of sense, in contradiction to the habitual persuasion of his judgement, is by contriving to forget everything that can be offered against them.
If, notwithstanding all his endeavours, the unwished for idea intrudes, the indulgence instantly becomes impossible. Is it to be supposed that the power of sensual allurement, which must be carefully kept alive, and which the slightest accident overthrows, can be invincible only to the artillery of reason, and that the most irresistible considerations of justice, interest and happiness will never be able habitually to control it?
