When we point out, in the situation of a people, circumstances which, by determining their pursuits, regulate their habits, and their manner of life; and when, instead of referring to the supposed physical source of their dispositions, we assign their inducements to a determinate conduct; in this we speak of effects and of causes whose connection is more familiarly known. We can understand, for instance, why a race of men like the Samoiede, confined, during great part of the year, to darkness, or retired into caverns, should differ, in their manners and apprehensions, from those who are at liberty in every season; or who, instead of seeking relief from the extremities of cold, are employed in search of precautions against the oppressions of a burning sun. Fire and exercise are the remedies of cold; repose and shade the securities from heat. The Hollander is laborious and industrious in Europe; he becomes more languid and slothful in India.(6*)Great extremities, either of heat or cold, are, perhaps, in a moral view, equally unfavourable to the active genius of mankind, and by presenting alike unsuperable difficulties to be overcome, or strong inducements to indolence and sloth, equally prevent the first applications of ingenuity, or limit their progress. Some intermediate degrees of inconvenience in the situation, at once excite the spirit, and, with the hopes of success, encourage its efforts. 'It is in the least favourable situations,' says Mr Rousseau, 'that arts have flourished the most. I could show them in Egypt, as they spread with the overflowing of the Nile; and in Africa, as they mounted up to the clouds, from a rocky soil and from barren sands; while on the fertile banks of the Eurotas, they were not able to fasten their roots.'

Where mankind from the first subsist by toil, and in the midst of difficulties, the defects of their situation are supplied by industry. and while dry, tempting, and healthful lands are left uncultivated,(7*) the pestilent marsh is drained with great labour, and the Sea is fenced off with mighty barriers, the materials and the costs of which, the soil to be gained can scarcely afford, or repay. Harbours are opened, and crouded with shipping, where vessels of burden, if they are not constructed with a view to the situation, have not water to float. Elegant and magnificent edifices are raised on foundations of slime; and all the conveniencies of human life are made to abound, where nature does not seem to have prepared a reception for men. It is in vain to expect, that the residence of arts and commerce should be determined by the possession of natural advantages. Men do more when they have certain difficulties to surmount, than when they have supposed blessings to enjoy: and the shade of the barren oak and the pine are more favourable to the genius of mankind, than that of the palm or the tamarind.

Among the advantages which enable nations to run the career of policy, as well as of arts, it may be expected, from the observations already made, that we should reckon every circumstance which enables them to divide and to maintain themselves in distinct and independent communities. The society and concourse of other men, are not more necessary to form the individual, than the rivalship and competition of nations are to invigorate the principles of political life in a state. Their wars, and their treaties, their mutual jealousies, and the establishments which they devise with a view to each other, constitute more than half the occupations of mankind, and furnish materials for their greatest and most improving exertions. For this reason, clusters of islands, a continent divided by many natural barriers, great rivers, ridges of mountains, and arms of the sea, are best fitted for becoming the nursery of independent and respectable nations. The distinction of states being clearly maintained, a principle of political life is established in every division, and the capital of every district, like the heart in an animal body, communicates with ease the vital blood and the national spirit to its members.

The most respectable nations have always been found where at least one part of the frontier has been washed by the sea. This barrier, perhaps the strongest of all in the times of barbarity, does not, however, even then supersede the cares of a national defence; and in the advanced state of arts, gives the greatest scope and facility to commerce.

Thriving and independent nations were accordingly scattered on the shores of the Pacific and the Atlantic. They surrounded the Red sea, the Mediterranean, and the Baltic; while, a few tribes excepted, who retire among the mountains bordering on India and Persia, or who have found some rude establishment among the creeks and the shores of the Caspian and the Euxine, there is scarcely a people in the vast continent of Asia who deserves the name of a nation. The unbounded plain is traversed at large by hordes, who are in perpetual motion, or who are displaced and harassed by their mutual hostilities. Although they are never perhaps actually blended together in the course of hunting, or in the search of pasture, they cannot bear one great distinction of nations, which is taken from the territory, and which is deeply impressed by an affection to the native seat. They move in troops, without the arrangement or the concert of nations; they become easy accessions to every new empire among themselves, or to the Chinese and the Muscovite, with whom they hold a traffic for the means of subsistence, and the materials of pleasure.

Where a happy system of nations is formed, they do not rely for the continuance of their separate names, and for that of their political independence, on the barriers erected by nature.
