I have said that the conditions necessary for the development of a civilization are--the aggregation of large masses, and stable institutions resulting from common views and interests. The sociable inclinations of man, and the less noble attributes of his nature, perform the rest. While the former bring him in intimate and varied connections with his fellow-men, the latter give rise to continual contests and emulation. In a large community, a strong fist is no longer sufficient to insure protection and give distinction, and the resources of the mind are applied and developed. Intellect continually seeks and finds new fields for exertion, either in the regions of the abstract, or in the material world. By its productions in either, we recognize an advanced state of society. The most common source of error in judging foreign nations, is that we are apt to look merely at the exterior demonstrations of their civilization, and because, in this respect, their civilization does not resemble ours, we hastily conclude that they are barbarous, or, at least, greatly inferior to us. A conclusion, drawn from such premises, must needs be very superficial, and therefore ought to be received with caution. I believe myself now prepared to express my idea of a civilization, by defining it as _A state of comparative stability, in which a large collection of individuals strive, by peaceful means, to satisfy their wants, and refine their intelligence and manners._ This definition includes, without exception, all the nations which I have mentioned as being civilized. But, as these nations have few points of resemblance, the question suggests itself: Do not, then, all civilizations tend to the same results? I think not; for, as the nations called to the noble task of accomplishing a civilization, are endowed with the utilitarian and speculative tendencies in various degrees and proportions, their paths must necessarily lie in very divergent directions.
