In its first half century the United States was visited by scores of curious European travellers who came to investigate the strange new world that was being created in the Western Hemisphere. In their accounts of the experience they praised, or condemned, the institutions and national characteristics spread out before them, seized avidly upon all differences from the European norm, and worried each peculiarity beyond recognition and beyond any just limit of its importance. Americans themselves, with the keen sensitiveness of the young and the boasting enthusiasm natural to vigorous creators of new ideas and institutions, examined the work of their hands and, believing it good, reassured themselves and answered their calumniators in a flood of aggressive replies. Every American interested in a reform movement, a new cult, or a Utopian scheme burst into print, adding another to the rapidly growing list of polemic books and pamphlets. From this variety of sources, it is possible to recapture something of the inward spirit that gave rise to the more familiar and more tangible events of America’s youth.
