"Does not Greece," said I, "furnish the clearest proof of the influence of moral causes on the character of nations? Compare what that country formerly was, with what it now is. Once superior to all the rest of the habitable globe, (of which it did not constitute the thousandth part,) in letters, arts, and arms, and all that distinguishes men from brutes; not merely in their own estimation, (for all nations are disposed to rate themselves high enough,) but by the general consent of the rest of the world. Do not the most improved and civilized of modern states still take them as their instructors and guides in every species of literature--in philosophy, history, oratory, poetry, architecture, and sculpture? And those too, who have attained superiority over the world, in arms, yield a voluntary subjection to the Greeks in the arts. The cause of their former excellence and their present inferiority, is no doubt to be found in their former freedom and their present slavery, and in the loss of that emulation which seems indispensable to natural greatness."
"Nay," replied he, "I am very far from denying the influence of moral causes on national character. The history of every country affords abundant evidence of it. I mean only to say, that though it does much, it does not do every thing. It seems more reasonable to impute the changes in national character to the mutable habits and institutions of man, than to nature, which is always the same. But if we look a little nearer, we may perhaps perceive, that amidst all those mutations in the character of nations, there are still some features that are common to the same people at all times, and which it would therefore be reasonable to impute to the great unvarying laws of nature. Thus it requires no extraordinary acuteness of observation, no strained hypothesis, to perceive a close resemblance between the Germans or the Britons of antiquity and their modern descendants, after the lapse of eighteen centuries, and an entire revolution in government, religion, language, and laws. And travellers still perceive among the inhabitants of modern Greece, deteriorated and debased as they are by political servitude, many of those qualities which distinguished their predecessors: the same natural acuteness--the same sensibility to pleasure--the same pliancy of mind and elasticity of body--the same aptitude for the arts of imitation--and the same striking physiognomy. That bright, serene sky--that happy combination of land and water, constituting the perfection of the picturesque, and that balmy softness of its air, which have proved themselves so propitious to forms of beauty, agility, and strength, also operate benignantly on the mind which animates them. Whilst the fruit is still fair to the eye, it is not probable that it has permanently degenerated in fragrance or flavour. The great diversities of national character may, perhaps, be attributed principally to moral and accidental causes, but partly also to climate, and to original diversities in the different races of man."
