This original tendency exhibits itself among human beings in a variety of ways. The tendency of human beings to herd together, for which there is evidence in the earliest history of the race, may be observed on any crowded thoroughfare, or in any amusement park, or city. That group life has expanded partly through practical necessity, is, of course, true, but groups of humans tend to become, as in our monster cities, larger than they need be, or can be for economic efficiency. The fascination of city life has not infrequently been set down to the multiplicity of opportunities offered in the way of companions, amusements, and occupations after one's own taste. But the fascination has clearly a more instinctive basis, the desire to be with other people. Many a man, as has been pointed out, lives in a large city as unsociable and secluded a life as if he were surrounded by miles of mountain or prairie, who yet could not be happy elsewhere. Any one who has failed to be amused by a really good comedy when the theater was comparatively empty, or in the presence of thousands of others hugely enjoyed a second-rate baseball game, or gone down to the crowded shopping district to get what he could have purchased on a side-street uptown, can appreciate how instinctive is this undiscriminating desire for companionship. The native intensity of this desire is what makes rural isolation, on the other hand, so unsatisfactory. The bleakness of New England country life as pictured in Edith Wharton's _Ethan Frome_, or in some of Robert Frost's _North of Boston_, is due more than anything else to this privation from companionship. Perhaps nothing better could be said for the rural telephone, the interurban trolley, and the cheap automobile than that they make possible the fulfillment of this normal human longing to be near and with other people in body and spirit. The horror which makes it practically impossible in civilized countries to legalize punishment by solitary confinement and the nervous collapse which such confinement brings about are indications of how deep-seated is this desire.
