It may perhaps be useful to consider how far these reasonings upon the subject of liberty are confirmed to us by general experience as to the comparative inefficacy of climate, and the superior influence of circumstances, political and social. The following instances are for the most part abridged from the judicious collections of Hume upon the subject.
1. If the theory here asserted be true, we may expect to find the inhabitants of neighbouring provinces in different states widely discriminated by the influence of government, and little assimilated by resemblance of climate.
Thus the Gascons are the gayest people in France; but the moment we pass the Pyrenees, we find the serious and saturine character of the Spaniard.
Thus the Athenians were lively, penetrating and ingenious; but the Thebans unpolished, phlegmatic and dull. 2. It would be reasonable to expect that different races of men, intermixed with each other, but differently governed, would afford a strong and visible contrast. Thus the Turks are brave, open and sincere; but the modern Greeks mean, cowardly and deceitful. 3. Wandering tribes closely connected among themselves, and having little sympathy with the people with whom they reside, may be expected to have great similarity of manners. Their situation renders them conspicuous, the faults of individuals reflect dishonour upon the whole, and their manners will be particularly sober and reputable, unless they should happen to labour under so peculiar an odium as to render all endeavour after reputation fruitless. Thus the Armenians in the East are as universally distinguished among the nations with whom they reside as the Jews in Europe; but the Armenians are noted for probity, and the Jews for extortion. 4. What resemblance is there between the ancient and the modern Greeks, between the old Romans and the present inhabitants of Italy, between the Gauls and the French? Diodorus Siculus describes the Gauls as particularly given to taciturnity, and Aristotle affirms that they are the only warlike nation who are negligent of women.
If on the contrary climate were principally concerned in forming the characters of nations, we might expect to find that heat and cold producing an extraordinary effect upon men, as they do upon plants and inferior animals.
