within their scope, and is capable of explanation by definition and principles. Otherwise they go wrong altogether, for they only judge rightly upon principles clearly set forth and established. On the other hand, subtle men, who are only subtle, lack patience, in matters of speculation and imagination, to reach first principles which they have never known in the world, and which are entirely beyond their beat. . . . “There are different kinds of sound sense. Some succeed in one order of things, and not in another, in which they are simply extravagant. . . . Some minds draw consequences well from a few principles, others are more at home in drawing conclusions from a great variety of principles. For example, some understand well the phenomena of water, with reference to which the principles are few, but the results extremely delicate, so that only very great accuracy of mind can trace them. Such men would probably not be great geometers, because geometry involves a multitude of principles, and because the mind which may penetrate thoroughly a few principles to their depth may not be at all able to penetrate things which combine a multitude of principles. . . . There are two sorts of mind: the one fathoms rapidly and deeply the consequences of principles—this is the observant and accurate mind; the other embraces a great multitude of principles, without confounding them—and this is the mathematical mind. The one is marked by energy and accuracy, the other by amplitude. But the one may exist without the other. The mind may be powerful and narrow, or it may be ample and weak.” {168} Few of Pascal’s Thoughts are more interesting than those on “Eloquence and Style.” So great a master of the art of expression had naturally something to say on these subjects. “Continued eloquence wearies. Princes and kings amuse themselves sometimes; they are not always upon their thrones—they tire of these. Grandeur must be laid aside in order to be realised. “Eloquence is a picture of thought; and thus those who, after having drawn a picture, still go on, make a tableau and not a likeness.
