Can we escape this brooding melancholy of the great workers--has any truly intellectual person escaped it ever? The question can never be answered with perfect certainty, because we can never quite accurately know the whole truth about the life of another. I have known several men of action, almost entirely devoid of intellectual culture, who enjoyed an unbroken flow of animal energy and were clearly free from the melancholy of Dürer; but I never intimately knew a really cultivated person who had not suffered from it more or less, and the greatest sufferers were the most conscientious thinkers and students. Amongst the illustrious dead, it may be very safely answered that any poet who has described it has written from his own experience--a transient experience it may be, yet his own. When Walter Scott, _à-propos_ of Dryden, spoke of "the apparently causeless fluctuation of spirits incident to one doomed to labor incessantly in the feverish exercise of the imagination," and of that "sinking of spirit which follows violent mental exertion," is it not evident that his kindly understanding of Dryden's case came from the sympathy of a fellow-laborer who knew by his own experience the gloomier and more depressing passages of the imaginative life? It would be prudent perhaps to omit the mention of Byron, because some may attribute his sadness to his immorality; and if I spoke of Shelley, they might answer that he was "sad because he was impious;" but the truth is, that quite independently of conduct, and even of belief, it was scarcely possible for natures so highly imaginative as these two, and so ethereally intellectual as one of the two, to escape those clouds of gloom which darken the intellectual life. Wordsworth was not immoral, Wordsworth was not unorthodox, yet he could be as sad in his own sober way as Byron in the bitterness of his desolation, or Shelley in his tenderest wailing. The three men who seem to have been the least subject to the sadness of intellectual workers were Alexander Humboldt, Cuvier, and Goethe. Alexander Humboldt, so far as is known to us, lived always in a clear and cheerful daylight; his appetite for learning was both strong and regular; he embraced the intellectual life in his earliest manhood, and lived in it with an unhesitating singleness of purpose, to the limits of extreme old age. Cuvier was to the last a model student, of a temper at once most unflinching and most kind, happy in all his studies, happier still in his unequalled facility of mental self-direction. Goethe, as all know, lived a life of unflagging interest in each of the three great branches of intellectual labor. During the whole of his long life he was interested in literature, in which he was a master; he was interested in science, in which he was a discoverer, and in art, of which he was an ardent though not practically successful student. His intellectual activity ceased only on rare occasions of painful illness or
