From the impossibility of confining numbers to the constant and uniform prosecution of a common interest, arises the difficulty of securing subjects against the encroachment of governours. Power is always gradually stealing away from the many to the few, because the few are more vigilant and consistent; it still contracts to a smaller number, till in time it centres in a single person. Thus all the forms of governments instituted among mankind, perpetually tend towards monarchy; and power, however diffused through the whole community, is, by negligence or corruption, commotion or distress, reposed at last in the chief magistrate. "There never appear," says Swift, "more than five or six men of genius in an age; but if they were united, the world could not stand before them." It is happy, therefore, for mankind, that of this union there is no probability. As men take in a wider compass of intellectual survey, they are more likely to choose different objects of pursuit; as they see more ways to the same end, they will be less easily persuaded to travel together; as each is better qualified to form an independent scheme of private greatness, he will reject with greater obstinacy the project of another; as each is more able to distinguish himself as the head of a party, he will less readily be made a follower or an associate. The reigning philosophy informs us, that the vast bodies which constitute the universe, are regulated in their progress through the ethereal spaces by the perpetual agency of contrary forces; by one of which they are restrained from deserting their orbits, and losing themselves in the immensity of heaven; and held off by the other from rushing together, and clustering round their centre with everlasting cohesion. The same contrariety of impulse may be perhaps discovered in the motions of men: we are formed for society, not for combination; we are equally unqualified to live in a close connexion with our fellow-beings, and in total separation from them; we are attracted towards each other by general sympathy, but kept back from contact by private interests.
