Haller scarcely treated any subjects but the super-sensuous, and part of the poems of Klopstock are also of this nature: this choice itself excludes them from the simple kind. Accordingly, in order to treat these super-sensuous themes in a poetic fashion, as no body could be given to them, and they could not be made the objects of sensuous intuition, it was necessary to make them pass from the finite to the infinite, and raise them to the state of objects of spiritual intuition. In general, it may be said, that it is only in this sense that a didactic poetry can be conceived without involving contradiction; for, repeating again what has been so often said, poetry has only two fields, the world of sense and the ideal world, since in the sphere of conceptions, in the world of the understanding, it cannot absolutely thrive. I confess that I do not know as yet any didactic poem, either among the ancients or among the moderns, where the subject is completely brought down to the individual, or purely and completely raised to the ideal. The most common case, in the most happy essays, is where the two principles are used together; the abstract idea predominates, and the imagination, which ought to reign over the whole domain of poetry, has merely the permission to serve the understanding. A didactic poem in which thought itself would be poetic, and would remain so, is a thing which we must still wait to see. What we say here of didactic poems in general is true in particular of the poems of Haller. The thought itself of these poems is not poetical, but the execution becomes so sometimes, occasionally by the use of images, at other times by a flight towards the ideal. It is from this last quality only that the poems of Haller belong to this class. Energy, depth, a pathetic earnestness—these are the traits that distinguish this poet. He has in his soul an ideal that enkindles it, and his ardent love of truth seeks in the peaceful valleys of the Alps that innocence of the first ages that the world no longer knows. His complaint is deeply touching; he retraces in an energetic and almost bitter satire the wanderings of the mind and of the heart, and he lovingly portrays the beautiful simplicity of nature. Only, in his pictures as well as in his soul, abstraction prevails too much, and the sensuous is overweighted by the intellectual. He constantly _teaches_ rather than _paints_; and even in his paintings his brush is more energetic than lovable. He is great, bold, full of fire, sublime; but he rarely and perhaps never attains to beauty.
