THOSE who employ their pens on political subjects, free from party-rage, and party-prejudices, cultivate a science, which, of all others, contributes most to public utility, and even to the private satisfaction of those who addict themselves to the study of it. I am apt, however, to entertain a suspicion, that the world is still too young to fix many general truths in politics, which will remain true to the latest posterity. We have not as yet had experience of three thousand years; so that not only the art of reasoning is still imperfect in this science, as in all others, but we even want sufficient materials upon which we can reason. It is not fully known, what degree of refinement, either in virtue or vice, human nature is susceptible of; nor what may be expected of mankind from any great revolution in their education, customs, or principles. MACHIAVEL was certainly a great genius; but having confined his study to the furious and tyrannical governments of ancient times, or to the little disorderly principalities of ITALY, his reasonings especially upon monarchical government, have been found extremely defective; and there scarcely is any maxim in his prince, which subsequent experience has not entirely refuted. A weak prince,[1] says he, is incapable of receiving good counsel; for if he consult with several, he will not be able to choose among their different counsels. If he abandon himself to one, that minister may, perhaps, have capacity; but he will not long be a minister: He will be sure to dispossess his master, and place himself and his family upon the throne. I mention this, among many instances of the errors of that politician, proceeding, in a great measure, from his having lived in too early an age of the world, to be a good judge of political truth. Almost all the princes of EUROPE are at present governed by their ministers; and have been so for near two centuries; and yet no such event has ever happened, or can possibly happen.
