Here is a little food for thought (bold and italics, mine):
Democratic poets will always appear trivial and frigid if they seek to invest gods, demons, or angels with corporeal forms, and if they attempt to draw them down from heaven to dispute the supremacy of earth. But if they strive to connect the great events they commemorate with the general providential designs which govern the universe, and, without showing the finger of the Supreme Governor, reveal the thoughts of the Supreme Mind, their works will be admired and understood, for the imagination of their contemporaries takes this direction of its own accord.
It may be foreseen that in like manner, that poets living in democratic times will prefer the delineation of passions and ideas to that of persons and achievements. The language, the dress, and the daily actions of men in democracies are repugnant to conceptions of the ideal. These things are not poetical in themselves because they are too familiar to all those to whom the poet would speak of them. This forces the poet constantly to search below the external surface which is palpable to the senses, in order to read the inner soul; and nothing lends itself more to the delineation of the ideal, than the scrutiny of the hidden depths in the immaterial nature of man. I need not traverse earth and sky to discover a wondrous object woven of contrasts, of infinite greatness and littleness, of intense gloom and amazing brightness, — capable at once of exciting pity, admiration, terror, contempt. I have only to look at myself. Man springs out of nothing, crosses time, and disappears forever in the bosom of God; he is seen but for a moment, wandering on the verge of the two abysses, and there he is lost.
If man were wholly ignorant of himself, he would have no Poetry in him; for it is impossible to describe what the mind does not conceive. If man clearly discerned his own nature, his imagination would remain idle, and would have nothing to add to the picture. But the nature of man is sufficiently disclosed for him to apprehend something of himself, and sufficiently obscure for all the rest to be plunged into thick darkness, in which he gropes forever, — and forever in vain, — to lay hold on some completer notion of his being.
Amongst a democratic people, Poetry will not be fed with legends or the memorials of old traditions. The poet will not attempt to people the universe with supernatural beings, in whom his readers and his own fancy have ceased to believe; nor will he coldly personify virtues and vices, which are better received under their own features. All these resources fail him; but Man remains, and the poet needs no more. The destinies of mankind – man himself, taken aloof from his country and his age, and standing in the presence of Nature and of God, with his passions, his doubts, his rare prosperities and inconceivable wretchedness — will become the chief, if not the sole, theme of Poetry amongst these nations.
Experience may confirm this assertion, if we consider the productions of the greatest poets who have appeared since the world has been turned to democracy. The authors of our age who have so admirably delineated the features of Faust, Childe Harold, Rene, and Jocelyn, did not seek to record the actions of an individual, but to enlarge and to throw light on some of the obscurer recesses of the human heart.
Such are the poems of democracy. The principle of equality does not then destroy all the subjects of Poetry: it renders them less numerous, but more vast.
