Not but that it has been, in all nations and times, of infinite practical service that there is involved in the constitution of the world a law by which a coarse self-interest thus interposes to obstruct in a degree the violent propensity to evil; for it has prevented, under Providence, more actual mischief, beyond comparison more, than all other causes together. The man inclined to perpetrate an iniquity, of the nature of a wrong to his fellow-mortals, is apprized that he shall provoke a reaction, to resist or punish him; that he shall incur as great an evil as that he is disposed to do, or greater; that either a revenge regardless of all formalities of justice will strike him, or a process instituted in organized society will vindictively reach his property, liberty, or life. This defensive array, of all men against all men, compels to remain shut up within the mind an immensity of wickedness which is there burning to come out into action. But for this, Noah's flood had been rendered needless. But for this, our planet might have been accomplishing its circles round the sun for thousands of years past without a human inhabitant. Through the effect of this essential law, in the social economy, it was possible for the race to subsist, notwithstanding all that ignorance of the Divine Being, of heavenly truth, and of uncorrupt morality, in which we are contemplating the heathen nations as benighted. But while thus it prevented utter destruction, it had no corrective operation on the depravity of the heart. It was not through a judgment of things being essentially evil that they were forborne; it was not by the power of conscience that wicked propensity was kept under restraint. It was only by a hold on the meaner principles of his nature, that the offender in will was arrested in prevention of the deed. And so the race were such virtually, as they would have hastened to become actually, could they have ceased to be afraid of one another's strength and retaliation.' [Footnote: It is not very uncommon to hear credit given to human nature apparently in sober simplicity, for the whole amount of the negation of bad actions _thus_ prevented, as just so much genuine virtue, by some dealers in moral and theological speculation.] But even this restraint imposed by mutual apprehension, important as its operation was in the absence of nobler influences, was yet of miserably partial efficacy. Men were continually breaking through this protective provision, and committed against one another a stupendous amount of crimes. And no wonder, when we consider that the evil passions, endowed as they seem to be with a portentous excess of vigor by the very circumstance of _being_ evil, (as the demoniacs were the strongest of men,) are exasperated the more by a certain degree of awe impressed on them by the defensive attitude of their objects. When strength so great might thus be irritated to greater, and when there were no "powers of the world to come," to invade the dreadful cavern of iniquity in the mind, and there combat and subdue it, there would often be no want of the audacity to send it forth into action at all hazards, and in defiance and contempt of the restraining force which operated through mutual fear of vindictive reaction.
