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, [Footnote: Compare the state of Hungary with that of Holland.] 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 crowded 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 enable 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 of an animal body, communicates with ease the vital blood and the national spirit to its members.
