Notwithstanding the advantage of numbers, and superior resources in war, the strength of a nation is derived from the character, not from the wealth, nor from the multitude of its people. If the treasure of a state can hire numbers of men, erect ramparts, and furnish the implements of war; the possessions of the fearful are easily seized; a timorous multitude falls into rout of itself; ramparts may be scaled where they are not defended by valour; and arms are of consequence only in the hands of the brave. The band to which Agesilaus pointed as the wall of his city, made a defence for their country more permanent, and more effectual, than the rock and the cement with which other cities were fortified. We should owe little to that statesman, who were to contrive a defence that might supersede the external uses of virtue. It is wisely ordered for man, as a rational being, that the employment of reason is necessary to his preservation; it is fortunate for him, in the pursuit of distinction, that his personal consideration depends on his character; and it is fortunate for nations, that, in order to be powerful and safe, they must strive to maintain the courage, and cultivate the virtues, of their people. By the use of such means, they at once gain their external ends, and are happy. Peace and unanimity are commonly considered as the principal foundations of public felicity; yet the rivalship of separate communities, and the agitations of a free people, are the principles of political life, and the school of men. How shall we reconcile these jarring and opposite tenets? It is, perhaps, not necessary to reconcile them. The pacific may do what they can to allay the animosities, and to reconcile the opinions, of men; and it will be happy if they can succeed in repressing their crimes, and in calming the worst of their passions. Nothing, in the mean time, but corruption or slavery can suppress the debates that subsist among men of integrity, who bear an equal part in the administration of state. A perfect agreement in matters of opinion is not to be obtained in the most select company; and if it were, what would become of society? "The Spartan legislator," says Plutarch, "appears to have sown the seeds of variance and dissention among his countrymen: he meant that good citizens should be led to dispute; he considered emulation as the brand by which their virtues were kindled; and seemed to apprehend, that a complaisance, by which men submit their opinions without examination, is a principal source of corruption."
