The very habits, indeed, of abstraction and self-study to which the occupations of men of genius lead, are, in themselves, necessarily, of an unsocial and detaching tendency, and require a large portion of indulgence from others not to be set down as unamiable. One of the chief sources, too, of sympathy and society between ordinary mortals being their dependence on each other's intellectual resources, the operation of this social principle must naturally be weakest in those whose own mental stores are most abundant and self-sufficing, and who, rich in such materials for thinking within themselves, are rendered so far independent of any aid from others. It was this solitary luxury (which Plato called "banqueting his own thoughts") that led Pope, as well as Lord Byron, to prefer the silence and seclusion of his library to the most agreeable conversation.--And not only too, is the necessity of commerce with other minds less felt by such persons, but, from that fastidiousness which the opulence of their own resources generates, the society of those less gifted than themselves becomes often a restraint and burden, to which not all the charms of friendship, or even love, can reconcile them. "Nothing is so tiresome (says the poet of Vaucluse, in assigning a reason for not living with some of his dearest friends) as to converse with persons who have not the same information as one's self." But it is the cultivation and exercise of the imaginative faculty that, more than any thing, tends to wean the man of genius from actual life, and, by substituting the sensibilities of the imagination for those of the heart, to render, at last, the medium through which he feels no less unreal than that through which he thinks. Those images of ideal good and beauty that surround him in his musings soon accustom him to consider all that is beneath this high standard unworthy of his care; till, at length, the heart becoming chilled as the fancy warms, it too often happens that, in proportion as he has refined and elevated his theory of all the social affections, he has unfitted himself for the practice of them.[52] Hence so frequently it arises that, in persons of this temperament, we see some bright but artificial idol of the brain usurp the place of all real and natural objects of tenderness. The poet Dante, a wanderer away from wife and children, passed the whole of a restless and detached life in nursing his immortal dream of Beatrice; while Petrarch, who would not suffer his only daughter to reside beneath his roof, expended thirty-two years of poetry and passion on an idealised love. It is, indeed, in the very nature and essence of genius to be for ever occupied intensely with Self, as the great centre and source of its strength. Like the sister Rachel, in Dante, sitting all day before her mirror, "mai non si smaga Del suo ammiraglio, e siede tutto giorno."
