According to some writers, the unequal distribution of solar heat over the earth is the cause of marked differences in national character; others refer the distinctive effects to the quality of the air they breathe. Arbuthnot maintains that air not only fashions the body, but has also had great influence in forming language; that the close, serrated method of speaking of Northern nations was due to coldness of the climate, and hesitation of opening the mouth; whilst the sweet, sonorous phrases of temperate climes, like those of the Mediterranean, were due to the mildness of climate, where the vocal organs could be exposed without danger. "It is incontestable," also writes Alfred Maury, in his "Earth and Man," "that climate has upon the mode of government a considerable influence, because it exercises an immediate effect upon the character of individuals. In the warm countries, under an enervating atmosphere, where all inclines to effeminacy and idleness, the soul has not that energy and that force of will necessary to a people who wish to be free. Under a severe and cold climate, to the contrary, the character acquires more of energy, and the body more of activity. The passions are less violent, and leave to the reason a freer exercise. In the hot climes the instincts are impetuous, and they pass from an extreme of dejection to a state of exaltation which produces revolutions, insurrections, but which do not establish the independence. For, to the contrary, these violent crises introduce retaliation; and in the sanguinary conflicts, the power of an individual, although tyrannical, appears as a benefit, or is accepted as a necessity."
