We repeat that these first productions are in nature a sort of assembling of resources; it matters little whether they be considered as _pasticcii_ or as _centoni_;[54] as little, perhaps, as to know that the child Michael Angelo often copied this or that antique statue; although with this difference, that the latter may have despaired of attaining such heights, while Bach, for aught we know, may have considered that what had already been achieved in his art was, after all, little more than so many sketches. [Footnote 54: _Centone_ (_It._): a composition made up of excerpts from other works.] To Buxtehude, Pachelbel, Froberger, F. Couperin, Frescobaldi, and still others--why name them all here?--belongs the proud distinction of having provided a _medium_ for Bach; and still their importance is not lessened by such a fact any more than is Bach's; in any case, it is very difficult to judge a man of genius without reference to chronological succession. Neither in the domain of art nor of science is furnished an example of a man creating a standard, of which his original conception has not been aided by one influence or another. Did Aristotle invent the syllogism, or did he not merely gather from about him some fragments of rudimentary procedure? And is not Bach the Aristotle of music, the master of musical reasoning, giving speech to his syllogisms in a form beautiful in itself, without taking into consideration the thought which it clothes? And is a fugue anything but a syllogism? Jenner (and we voluntarily take as examples fame become _banale_) did not intuitively discover vaccine. By a happy chance he established the fact that certain herds were immune from small-pox; accidentally hit on the truth, by following his conclusion to its cause. The man of genius is undeniably Pasteur, who generalizes a century later, assisted by the addition to the literature upon the subject of a mass of treatises, those of Davaine, of Villemain.... To cite Jenner in connection with our subject is more than amusing; but consider Frescobaldi--is he not the Jenner of the Fugue?... But let us avoid the necessity of classifying great men in the order of their merit; it is the evolution of Bach's genius which we wish to study. There is in this field an aspect of psychological analysis which we trust will prove of interest; but it is by no means our wish that any inference shall be drawn from the foregoing which could lead to an undervaluation of the originality of Johann Sebastian Bach.
