In the North the art of mercurial dialogue, which in the South is a natural gift, is only learned under favourable conditions, and is often condemned by those who have it not, as a popinjay's accomplishment. Immediate cordiality to strangers is frowned upon as tending to divorce courtesy from truth. It is otherwise with the southern peoples. While the Englishman conceals his benevolence by a frigid aloofness of manner, or blurts out friendliness like an indiscretion, the Italian is courtly without a second thought, and the Frenchman seems the comrade of a chance acquaintance from the moment when he has taken his hand. They are amiable without effort in the security of a harmonious nature, and if they encounter diffidence at all, observe it like an anthropologist confronted with a survival of primitive times in the culture of a civilized age.
Taine did not err when he found the home of shyness among the Teutonic peoples; he saw that it flourishes in climatic conditions acting hardly upon a vigorous race, and only allowing it to cultivate ease of manner by effort and outlay, just as they only allow it to raise under glass the grapes and oranges which more favoured peoples can grow in the open air. He saw too that this pain of diffidence becomes more subtle as the progress of culture makes us more sensitive to vague impressions from our environment, and tunes the nerves to a higher pitch. A shy nature upon this plane of susceptibility suffers anguish from an uncontrollable body; and even in peaceful moments the memory of the discomfitures so inflicted may distort a man's whole view of the world around him. He is impatient of the wit which demands a versatility in response beyond his powers, and persuades himself into contempt of those ephemeral arts to which his nature cannot be constrained. Irritated at the injustice which places so high in the general scale of values accomplishments which he cannot practise, shrinking from the suave devices of gesture and expression which in his own case might quickly pass into antic or grimace, he withdraws more and more from the places where such arts win esteem to live in a private world of inner sentiment. As he leaves this sure retreat but rarely himself, so he forbids ingress to others; and becoming yearly a greater recluse, he confines himself more and more within the walls of his forbidden city. The mind which may have been fitted to expand in the free play of intellectual debate or to explore the high peaks of idea, loses its power of flight in this cave where it dwells with a company of sad thoughts, until at last the sacrifice is complete and the perfect eremite is formed.
