No man of genius put forth more expansive promises of universal power than LEIBNITZ. Science, imagination, history, criticism, fertilized the richest of human soils; yet LEIBNITZ, with immense powers and perpetual knowledge, dissipated them in the multiplicity of his pursuits. "The first of philosophers," the late Professor Playfair observed, "has left nothing in the immense tract of his intellect which can be distinguished as a monument of his genius." As a universalist, VOLTAIRE remains unparalleled in ancient or in modern times. This voluminous idol of our neighbours stands without a rival in literature; but an exception, even if this were one, cannot overturn a fundamental principle, for we draw our conclusions not from the fortune of one man of genius, but from the fate of many. The real claims of this great writer to invention and originality are as moderate as his size and his variety are astonishing. The wonder of his ninety volumes is, that he singly consists of a number of men of the second order, making up one great man; for unquestionably some could rival Voltaire in any single province, but no one but himself has possessed them all. Voltaire discovered a new art, that of creating a supplement to the genius which had preceded him; and without Corneille, Racine, and Ariosto, it would be difficult to conjecture what sort of a poet Voltaire could have been. He was master, too, of a secret in composition, which consisted in a new style and manner. His style promotes, but never interrupts thinking, while it renders all subjects familiar to our comprehension: his manner consists in placing objects well known in new combinations; he ploughed up the fallow lands, and renovated the worn-out exhausted soils. Swift defined a good style, as "proper words in proper places." Voltaire's impulse was of a higher flight, "proper thoughts on proper subjects." Swift's idea was that of a grammarian. Voltaire's feeling was that of a philosopher. We are only considering this universal writer in his literary character, which has fewer claims to the character of an inventor than several who never attained to his celebrity.
