The state of passion in itself, independently of the good or bad influence of its object on our morality, has something in it that charms us. We aspire to transport ourselves into that state, even if it costs us some sacrifices. You will find this instinct at the bottom of all our most habitual pleasures. As to the nature itself of the affection, whether it be one of aversion or desire, agreeable or painful, this is what we take little into consideration. Experience teaches us that painful affections are those which have the most attraction for us, and thus that the pleasure we take in an affection is precisely in an inverse ratio to its nature. It is a phenomenon common to all men, that sad, frightful things, even the horrible, exercise over us an irresistible seduction, and that in presence of a scene of desolation and of terror we feel at once repelled and attracted by two equal forces. Suppose the case be an assassination. Then every one crowds round the narrator and shows a marked attention. Any ghost story, however embellished by romantic circumstances, is greedily devoured by us, and the more readily in proportion as the story is calculated to make our hair stand on end. This disposition is developed in a more lively manner when the objects themselves are placed before our eyes. A tempest that would swallow up an entire fleet would be, seen from shore, a spectacle as attractive to our imagination as it would be shocking to our heart. It would be difficult to believe with Lucretius that this natural pleasure results from a comparison between our own safety and the danger of which we are witnesses. See what a crowd accompanies a criminal to the scene of his punishment! This phenomenon cannot be explained either by the pleasure of satisfying our love of justice, nor the ignoble joy of vengeance. Perhaps the unhappy man may find excuses in the hearts of those present; perhaps the sincerest pity takes an interest in his reprieve: this does not prevent a lively curiosity in the spectators to watch his expressions of pain with eye and ear. If an exception seems to exist here in the case of a well-bred man, endowed with a delicate sense, this does not imply that he is a complete stranger to this instinct; but in his case the painful strength of compassion carries the day over this instinct, or it is kept under by the laws of decency. The man of nature, who is not chained down by any feeling of human delicacy, abandons himself without any sense of shame to this powerful instinct. This attraction must, therefore, have its spring of action in an original disposition, and it must be explained by a psychological law common to the whole species.
