TWO: One of the greatest preventives of crimes is, not the cruelty of the punishments attached to them, but their infallibility, and consequently that watchfulness on the part of the magistrates and that inexorable severity on the part of the judge which, to be a useful virtue, must coincide with a mild system of laws. The certainty of a punishment, moderate though it be, will ever make a stronger impression than the fear of another, more terrible, perhaps, but associated with the hope of impunity; for even the least evils when certain always terrify mens minds, and hope, that gift of heaven, which often makes up to us for everything, always throws into the distance the idea of greater evils, especially when its force is increased by impunity, which avarice and weakness so often grant.Laws are the conditions under which men, leading independent and isolated lives, joined together in society, when tired of living in a perpetual state of war, and of enjoying a liberty which the uncertainty of its tenure rendered useless. Of this liberty they voluntarily sacrificed a part, in order to enjoy the remainder in security and quiet. The sum-total of all these portions of liberty, sacrificed for the good of each individually, constitutes the sovereignty of a nation, and the sovereign is the lawful trustee and administrator of these portions. But, besides forming this trust-fund, or deposit, it was necessary to protect it from the encroachments of individuals, whose aim it ever is not only to recover from the fund their own deposit, but to avail themselves of that contributed by others. Sensible motives, were therefore wanted to divert the despotic will of the individual from re-plunging into their primitive chaos the laws of society.[123] Such motives were found in punishments, established against transgressors of the laws; and I call them sensible motives, because experience has shown that the majority of men adopt no fixed rules of conduct, nor avoid that universal principle of dissolution, observable alike in the moral as in the physical world, save by reason of motives which directly strike the senses and constantly present themselves to the mind, counterbalancing the strong impressions of private passions, opposed as they are to the general welfare; not eloquence, nor declamations, nor the most sublime truths have ever sufficed to curb the passions for any length of time, when excited by the lively force of present objects.
