him know, that, the purer it is, the more temperate, tranquil, reposeful.  Truth is not to be run down with fox-hounds; she is a divinity, and divinely must he draw nigh who will gain her presence.  Go to, thou bluster-brain!  Dost thou think to learn?  Learn docility first, and the manners of the skies.  And thou egotist, thinkest thou that these eyes of thine, smoky with the fires of diseased self-love, and thronged with deceiving wishes, shall perceive the essential and eternal?  They shall see only silver and gold, houses and lands, reputes, supremacies, fames, and, as instrumental to these, the forms of logic and seemings of knowledge.  If thou wilt discern the truth, desire IT, not its accidents and collateral effects.  Rest in the pursuit of it, putting simplicity of quest in the place of either force or wile; and such quest cannot be unfruitful.

Let the student, then, shun an excited and spasmodic tension of brain, and he will gain more while expending less.  It is not toil, it is morbid excitement, that kills; and morbid excitement in constant connection with high mental endeavor is, of all modes and associations of excitement, the most disastrous.  Study as the grass grows, and your old age—­and its laurels—­shall be green.

Already, however, we are trenching upon that more intimate relationship of the great opposites under consideration which has been designated Rest in Motion.  More intimate relationship, I say,—­at any rate, more subtile, recondite, difficult of apprehension and exposition, and perhaps, by reason of this, more central and suggestive.  An example of this in its physical aspect may be seen in the revolutions of the planets, and in all orbital or circular motion.  For such, it will be at once perceived, is, in strictness of speech, fixed and stationary motion:  it is, as Sir Isaac Newton demonstrated, an exact and equal obedience, in the same moment, to the law of fixity and the law of progression.  Observe especially, that it is not, like merely retarded motion, a partial neutralization of each principle by the other, an imbecile Aristotelian compromise and half-way house between the two; but it is at once, and in virtue of the same fact, perfect Rest and perfect Motion.  A revolving body is not hindered, but the same impulse which begot its movement causes this perpetually to return into itself.

Now the principles that are seen to govern the material universe are but a large-lettered display of those that rule in perfect humanity.  Whatsoever makes distinguished order and admirableness in Nature makes the same in man; and never was there a fine deed that was not begot of the same impulse and ruled by the same laws to which solar systems are due.  I desire, accordingly, here to take up and emphasize the statement previously made in a general way,—­that the secret of perfection in all that appertains to man—­in morals, manners, art, politics—­must be sought in such a correspondence and reciprocation of these great opposites as the motions of the planets perfectly exemplify.
