And yet this devotedness or devotion, this reverence for authority, is but one element of excellence. To reverence is good; but on the one condition that the object of it be a thing which deserves reverence; and the necessary complement, the security that we are not bestowing our best affections where they should not be given, must be looked for in some quality which, if less attractive, is no less essential for our true welfare. To prove all things--to try the spirits whether they be of God--is a duty laid upon us by the highest authority; and what is called progress in human things--religious as well as material--has been due uniformly to a dissatisfaction with them as they are. Every advance in science, every improvement in the command of the mechanical forces of nature, every step in political or social freedom, has risen in the first instance from an act of scepticism, from an uncertainty whether the formulas, or the opinions, or the government, or the received practical theories were absolutely perfect; or whether beyond the circle of received truths there might not lie something broader, deeper, truer, and thus better deserving the acceptance of mankind. Submissiveness, humility, obedience, produce if uncorrected, in politics a nation of slaves, whose baseness becomes an incentive to tyranny; in religion, they produce the consecration of falsehood, poperies, immaculate conceptions, winking images, and the confessional. The spirit of enquiry if left to itself becomes in like manner a disease of uncertainty, and terminates in universal scepticism. It seems as if in a healthy order of things, to the willingness to believe there should be chained as its inseparable companion a jealousy of deception; and there is no lesson more important for serious persons to impress upon themselves than that each of these temperaments must learn to tolerate the other; faith accepting from reason the sanction of its service, and reason receiving in return the warm pulsations of life. The two principles exist together in the highest natures; and the man who in the best sense of the word is devout, is also the most cautious to whom or to what he pays his devotion. Among the multitude, the units of which are each inadequate and incomplete, the elements are disproportionately mixed; some men are humble and diffident, some are sceptical and enquiring; yet both are filling a place in the great intellectual economy; both contribute to make up the sum and proportion of qualities which are required to hold the balance even; and neither party is entitled to say to the other, 'Stand by; I am holier than thou.'
