It is a sign of our times, conspicuous to the coarsest observer, that many intelligent and religious persons withdraw themselves from the common labors and competitions of the market and the caucus, and betake themselves to a certain solitary and critical way of living, from which no solid fruit has yet appeared to justify their separation. They hold themselves aloof: they feel the disproportion between their faculties and the work offered them, and they prefer to ramble in the country and perish of ennui, to the degradation of such charities and such ambitions as the city can propose to them. They are striking work, and crying out for somewhat worthy to do! What they do, is done only because they are overpowered by the humanities that speak on all sides; and they consent to such labor as is open to them, though to their lofty dream the writing of Iliads or Hamlets, or the building of cities or empires seems drudgery. Now every one must do after his kind, be he asp or angel, and these must. The question, which a wise man and a student of modern history will ask, is, what that kind is? And truly, as in ecclesiastical history we take so much pains to know what the Gnostics, what the Essenes, what the Manichees, and what the Reformers believed, it would not misbecome us to inquire nearer home, what these companions and contemporaries of ours think and do, at least so far as these thoughts and actions appear to be not accidental and personal, but common to many, and the inevitable flower of the Tree of Time. Our American literature and spiritual history are, we confess, in the optative mood; but whoso knows these seething brains, these admirable radicals, these unsocial worshippers, these talkers who talk the sun and moon away, will believe that this heresy cannot pass away without leaving its mark.
