In short, the maxim of preserving the balance of power is {p75} founded so much on common sense and obvious reasoning that it is impossible it could altogether have escaped antiquity, where we find, in other particulars, so many marks of deep penetration and discernment. If it was not so generally known and acknowledged as at present, it had at least an influence on all the wiser and more experienced princes and politicians; and indeed, even at present, however generally known and acknowledged among speculative reasoners, it has not, in practice, an authority much more extensive among those who govern the world.
