It remains for me to observe, by way of stimulating the ambition of British genius, that, in France, the arts and sciences are now making a rapid and simultaneous progress; first, because the revolution has made them popular in that country; and, secondly, because they are daily connected by new ties, which, in a great measure, render them inseparable. Facts are there recurred to, less with a view to draw from them immediate applications than to develop the truths resulting from them. The first step is from these facts to their most simple consequences, which are little more than bare assertions. From these the _savans_ proceed to others more minute, till, at length, by imperceptible degrees, they arrive at the most abstracted generalities. With them, method is an induction incessantly verified by experiment. Whence, it gives to human intelligence, not wings which lead it astray, but reins which guide it. United by this common philosophy, the sciences and arts in France advance together; and the progress made by one of them serves to promote that of the rest. There, the men who profess them, considering that their knowledge belongs not to themselves alone, not to their country only, but to all mankind, are continually striving to increase the mass of public knowledge. This they regard as a real duty, which they are proud to discharge; thus treading in the steps of the most memorable men of past ages. Then, while the more unlearned and unskilled among us are emulating the patriotic enthusiasm of the French in volunteering, as they did, to resist invasion, let our men of science and genius exert themselves not to be surpassed by the industrious _savans_ and artists of that nation; but let them act on the principle inculcated by the following sublime idea of our illustrious countryman, the founder of modern philosophy. "It may not be amiss," says BACON, "to point out three different kinds, and, as it were, degrees of ambition. The first, that of those who desire to enhance, in their own country, the power they arrogate to themselves: this kind of ambition is both vulgar and degenerate. The second, that of those who endeavour to extend the power and domination of their country, over the whole of the human race: in this kind there is certainly a greater dignity, though; at the same time, no less a share of cupidity. But should any one strive to restore and extend the power and domination of mankind over the universality of things, unquestionably such an ambition, (if it can be so denominated) would be more reasonable and dignified than the others. Now, the empire of man, over things, has its foundation exclusively in the arts and sciences; for it is only by an obedience to her laws, that Nature can be commanded."[3] LONDON, June 10, 1803.
