Politics not only give birth to numerous associations, but to associations of great extent. In civil life it seldom happens that any one interest draws a very large number of men to act in concert; much skill is required to bring such an interest into existence: but in politics opportunities present themselves every day. Now it is solely in great associations that the general value of the principle of association is displayed. Citizens who are individually powerless, do not very clearly anticipate the strength which they may acquire by uniting together; it must be shown to them in order to be understood. Hence it is often easier to collect a multitude for a public purpose than a few persons; a thousand citizens do not see what interest they have in combining together--ten thousand will be perfectly aware of it. In politics men combine for great undertakings; and the use they make of the principle of association in important affairs practically teaches them that it is their interest to help each other in those of less moment. A political association draws a number of individuals at the same time out of their own circle: however they may be naturally kept asunder by age, mind, and fortune, it places them nearer together and brings them into contact. Once met, they can always meet again. Men can embark in few civil partnerships without risking a portion of their possessions; this is the case with all manufacturing and trading companies. When men are as yet but little versed in the art of association, and are unacquainted with its principal rules, they are afraid, when first they combine in this manner, of buying their experience dear. They therefore prefer depriving themselves of a powerful instrument of success to running the risks which attend the use of it. They are, however, less reluctant to join political associations, which appear to them to be without danger, because they adventure no money in them. But they cannot belong to these associations for any length of time without finding out how order is maintained amongst a large number of men, and by what contrivance they are made to advance, harmoniously and methodically, to the same object. Thus they learn to surrender their own will to that of all the rest, and to make their own exertions subordinate to the common impulse--things which it is not less necessary to know in civil than in political associations. Political associations may therefore be considered as large free schools, where all the members of the community go to learn the general theory of association.
