The prince heard this narration with very serious regard; but the princess smiled, and Pekuah convulsed herself with laughter. “Ladies,” said Imlac, “to mock the heaviest of human afflictions is neither charitable nor wise. Few can attain this man’s knowledge, and few practise his virtues; but all may suffer his calamity. Of the uncertainties of our present state, the most dreadful and alarming is the uncertain continuance of reason.” The princess was recollected, and the favourite was abashed. Rasselas, more deeply affected, inquired of Imlac, whether he thought such maladies of the mind frequent, and how they were contracted. CHAPTER XLIV THE DANGEROUS PREVALENCE OF IMAGINATION “Disorders of intellect,” answered Imlac, “happen much more often than superficial observers will easily believe. Perhaps, if we speak with rigorous exactness, no human mind is in its right state. There is no man whose imagination does not sometimes predominate over his reason, who can regulate his attention wholly by his will, and whose ideas will come and go at his command. No man will be found in whose mind airy notions do not sometimes tyrannize, and force him to hope or fear beyond the limits of sober probability. All power of fancy over reason is a degree of insanity; but while this power is such as we can control and repress, it is not visible to others, nor considered as any depravation of the mental faculties: it is not pronounced madness but when it becomes ungovernable and apparently influences speech or action. “To indulge the power of fiction, and send imagination out upon the wing, is often the sport of those who delight too much in silent speculation. When we are alone we are not always busy; the labour of excogitation is too violent to last long; the ardour of inquiry will sometimes give way to idleness or satiety. He who has nothing external that can divert him, must find pleasure in his own thoughts, and must conceive himself what he is not; for who is pleased with what he is? He then expatiates in boundless futurity, and culls from all imaginable conditions that which for the present moment he should most desire, amuses his desires with impossible enjoyments, and confers upon his pride unattainable dominion. The mind dances from scene to scene, unites all pleasures in all combinations, and riots in delights, which nature and fortune, with all their bounty, cannot bestow. “In time some particular train of ideas fixes the attention; all other intellectual gratifications are rejected; the mind, in weariness or leisure, recurs constantly to the favourite conception, and feasts on the luscious falsehood whenever she is offended with the bitterness of truth. By degrees the reign of fancy is confirmed; she grows first imperious, and in time despotic. Then fictions begin to operate as realities, false opinions fasten upon the mind, and life passes in dreams of rapture or of anguish.
