It results from these considerations that there is no sphere of literature which is so often the refuge of wealthy scholars, idle men of taste, baffled politicians of independent means, ambitious and well-read but not specially gifted citizens who have inherited comfortable estates.  It is so dignified an employment, that it gratifies pride,—­so possible without trenchant opinions, that it does not alarm the conservative,—­so thoroughly respectable, safe, and capable of being made illustrious, so comparatively easy to the fluent but unoriginal mind, and practicable to follow, when methodically carried out, in a stated, regular manner, that we can scarcely be astonished at the alacrity with which such voluntary tasks are undertaken or the steadiness with which they are followed; at the same time, it may be because so few are able to command the means and opportunity, that historical writing is so highly estimated.  As a test of intellectual power, a gauge of individual sentiment, an evidence of original genius, it is immeasurably inferior to dramatic, philosophical, or any of the more personal forms of literature, when inspired by deep convictions, original ideas, or creative imagination.  It requires more knowledge than reflection, more patience than earnestness, more judgment than sentiment; and those who have raised it to a vital significance and profound beauty and interest have done so by virtue of endowments which, otherwise directed, would have placed them high and firm on the roll of genius:  for it is possible to write history without this transcendent gift,—­possible to write it respectably without the slightest grandeur or grace of mind,—­by virtue of command of words, industry, care, and good sense.  We cannot imagine Shakspeare tracing out his conception of Hamlet, or giving language to Lear or Miranda, without a soulful experience as far above mere intellectual assiduity as humanity is above mechanism; we cannot think of Milton elaborating his sublime epic, without, in fancy, taking in the studious years, the Italian nights of music, starlight, and high converse, the beautiful youth, the self-sacrificing prime, the blind old age, the religious patriotism, the pious loyalty, the learning and love, and the isolated meditation, cheered by grand symphonies and hoarded wisdom, through and by which, concentrated into melodious expression, the life of a noble mind thus majestically expressed itself:  but we can easily fancy cold and cultured Gibbon returning from the Continent, full of classic lore, disgusted with his failure in public life, not sympathetic enough to enjoy heartily a career either of pleasure or of society, and so, in his dreams of scholarship, seizing upon the idea of a long, laborious, erudite, and elegant task; and we can also well imagine Hume, with his love of speculation, turning gratefully to the records of the past for subjects of reflection, analysis, and inference.  In these and other notable instances, we feel it is more an accident than an inspiration, more from circumstances than from innate and absolute endowment and impulse, that the historic Muse is wooed.
