Book V. Line 429.
Eripuit coelo fulmen, sceptrumque tyrannis
This epigraph, written by Turgot on the bust of Franklin, seems to have been imitated from a line in Manilius; where noticing the progress of science in ascribing things to their natural and proper causes instead of supernatural ones, he says,
Eriput Jovi fulmen, viresque tonandi, Et sonitum ventis concessit, nubibus ignem.
No. 35
And Knox from his full park to battle brings
His brazen tubes, the last resort of kings.
Book V. Line 665.
Ultima ratio regum; a device of Louis XIV engraved on his ordnance, and afterwards adopted by other powers. When we consider men as reasonable beings and endowed with the qualities requisite for living together in society, this device looks like a satire upon the species; but in reality it only proves the imperfect state to which their own principles of society have yet advanced them in the long and perhaps interminable progress of which they are susceptible. This ultima ratio being already taken out of the hands of individuals and confided only to the chiefs of nations is as clear a proof of a great progress already made, as its remaining in the hands of those chiefs is a proof that we still remain far short of that degree of wisdom and experience which will enable all the nations to live at peace one with another.
There certainly was a time when the same device might have been written on the hatchet or club or fist of every man; and the best weapon of destruction that he could wield against his neighbour might have been called ultima ratio virarum, meaning that human reason could go no farther. But the wisdom we have drawn from experience has taught us to restrain the use of mortal weapons, making it unlawful and showing it to be unreasonable to use them in private disputes. The principles of social intercourse and the advantages of peace are so far understood as to enable men to form great societies, and to submit their personal misunderstandings to common judges; thus removing the ultima ratio from their own private hands to the hands of their government.
Hitherto there has usually been a government to every nation; but the nations are increasing in size and diminishing in number; so that the hands which now hold the ultima ratio by delegation are few, compared with what they have been. I mean this observation to apply only to those extensions of nationality which have been formed on the true principles of society and acquiesced in from a sense of their utility. I mean not to apply it to those unnatural and unwieldy stretches of power, whose overthrow is often and erroneously cited as an argument against the progress of civilization; such as the conquests of Alexander, the Roman generals, Omar, Gengis Khan and others of that brilliant description. These are but meteors of compulsive force, which pass away and discourage, rather than promote, the spirit of national extension of which I speak.
