A person may be frequently solitary without being alone. The haughty baron, proud of his illustrious descent, is solitary unless he is surrounded by his equals: a profound reasoner is solitary at the tables of the witty and the gay. The mind may be as abstracted amidst a numerous assembly; as much withdrawn from every surrounding object; as retired and concentrated in itself; as solitary, in short, as a monk in his cloister, or a hermit in his cave. Solitude, indeed, may exist amidst the tumultuous intercourse of an agitated city as well as in the peaceful shades of rural retirement; at London and at Paris, as well as on the plains of Thebes and the deserts of Nitria. The mind, when withdrawn from external objects, adopts, freely and extensively, the dictates of its own ideas, and implicitly follows the taste, the temperament, the inclination, and the genius, of its possessor. Sauntering through the cloisters of the Magdalen convent at Hidelshiem, I could not observe, without a smile, an aviary of canary birds, which had been bred in the cell of a female devotee. A gentleman of Brabant, lived five-and-twenty years without ever going out of his house, entertaining himself during that long period with forming a magnificent cabinet of pictures and paintings. Even unfortunate captives, who are doomed to perpetual imprisonment, may soften the rigors of their fate, by resigning themselves, as far as their situation will permit, to the ruling passion of their souls. Michael Ducret, the Swiss philosopher, while he was confined in the castle of Aarburg, in the canton of Berne, in Swisserland, measured the height of the Alps: and while the mind of baron Trenck, during his imprisonment at Magdebourg, was with incessant anxiety, fabricating projects to effect his escape, general Walrave, the companion of his captivity, contentedly passed his time in feeding chickens. The human mind, in proportion as it is deprived of external resources, sedulously labors to find within itself the means of happiness, learns to rely with confidence on its own exertions, and gains with greater certainty the power of being happy. A work, therefore, on the subject of solitude, appeared to me likely to facilitate man in his search after true felicity. Unworthy, however, as the dissipation and pleasures of the world appear to me to be, of the avidity with which they are pursued, I equally disapprove of the extravagant system which inculcates a total dereliction of society; which will be found, when seriously examined, to be equally romantic and impracticable. To be able to live independent of all assistance, except from our own power, is, I acknowledge, a noble effort of the human mind; but it is equally great and dignified to learn the art of enjoying the comforts of society with happiness to ourselves, and with utility to others.
