But what completes his picture, what signalizes the advance of science, is the fact that his imagination provides a counterbalance against itself. He is as fertile in doubts as he is in explanations. If he sees a thousand reasons which tend to one view, he sees also a thousand which tend to the contrary. At the two extremities of the same fact, he raises up to the clouds, but in equal piles, the scaffolding of contradictory arguments. Having made a guess, he knows that it is but a guess; he pauses, ends with a perhaps, recommends verification. His writings consist only of opinions, given as such; even his principal work is a refutation of popular errors. In the main, he proposes questions, suggests explanations, suspends his judgments, nothing more; but this is enough; when the search is so eager, when the paths in which it proceeds are so numerous, when it is so scrupulous in securing its hold, the issue of the pursuit is sure; we are but a few steps from the truth. SECTION V.--Francis Bacon In this band of scholars, dreamers, and inquirers, appears the most comprehensive, sensible, originative of the minds of the age, Francis Bacon, a great and luminous intellect, one of the finest of this poetic progeny, who, like his predecessors, was naturally disposed to clothe his ideas in the most splendid dress: in this age, a thought did not seem complete until it had assumed form and color. But what distinguishes him from the others is, that with him an image only serves to concentrate meditation. He reflected long, stamped on his mind all the parts and relations of his subject; he is master of it, and then, instead of exposing this complete idea in a graduated chain of reasoning, he embodies it in a comparison so expressive, exact, lucid, that behind the figure we perceive all the details of the idea, like liquor in a fine crystal vase. Judge of his style by a single example: "For as water, whether it be the dew of Heaven or the springs of the earth, easily scatters and loses itself in the ground, except it be collected into some receptacle, where it may by union and consort comfort and sustain itself (and for that cause, the industry of man hath devised aqueducts, cisterns, and pools, and likewise beautified them with various ornaments of magnificence and state, as well as for use and necessity); so this excellent liquor of knowledge, whether it descend from divine inspiration or spring from human sense, would soon perish and vanish into oblivion, if it were not preserved in books, traditions, conferences, and especially in places appointed for such matters as universities, colleges, and schools, where it may have both a fixed habitation, and means and opportunity of increasing and collecting itself."[384]
