ONE:But these periods of time will not be lengthened in exact proportion to the atrocity of crimes, since the probability of a crime is in inverse ratio to its atrocity. It will, then, be necessary to shorten the period for inquiry and to increase that of prescription; which[159] may appear to contradict what I said before, namely, that it is possible to inflict equal penalties on unequal crimes, by counting as a penalty that period of imprisonment or of prescription which precedes the verdict. To explain to the reader my idea: I distinguish two kinds of crimesthe first, atrocious crimes, beginning with homicide and including all the excessive forms of wickedness; the second comprising less considerable crimes. This distinction is founded in human nature. Personal security is a natural right, the security of property a social one. The number of motives which impel men to violate their natural affections is far smaller than those which impel them, by their natural longing for happiness, to violate a right which they do not find written in their hearts but only in the conventions of society. The very great difference between the probability of these two kinds of crime respectively makes it necessary that they should be ruled by different principles. In cases of the more atrocious crimes, because they are more uncommon, the time for inquiry ought to be so much the less as the probability of the innocence of the accused is greater; and the time of prescription ought to be longer, as on an ultimate definite sentence of guilt or innocence depends the destruction of the hope of impunity, the harm of which is proportioned to the atrocity of the crime. But in cases of lesser criminality, where the presumption in favour of a mans[160] innocence is less, the time for inquiry should be longer; and as the harm of impunity is less, the time of prescription should be shorter. But such a division of crimes ought, indeed, not to be admitted, if the danger of impunity decreased exactly in proportion to the greater probability of the crime. One should remember that an accused man, whose guilt or innocence is uncertain, may, though acquitted for lack of proofs, be subjected for the same crime to a fresh imprisonment and inquiry, in the event of fresh legal proofs rising up against him, so long as the time of prescription accorded by the laws has not been past. Such at least is the compromise that I think best fitted to preserve both the liberty and the security of the subject, it being only too easy so to favour the one at the expense of the other, that these two blessings, the inalienable and equal patrimony of every citizen, are left unprotected and undefended, the one from declared or veiled despotism, the other from the turbulence of civil anarchy.The lighting of a city by night at the public expense; the distribution of guards in the different quarters; simple moral discourses on religion, but only in the silent and holy quiet of churches, protected by public authority; speeches on behalf of private and public interests in national assemblies, parliaments, or wherever else the majesty of sovereignty residesall these are efficacious means for preventing the dangerous condensation of popular passions. These means are a principal branch of that magisterial vigilance which the French call police; but if this is exercised by arbitrary laws, not laid down in a code of general circulation, a door is opened to tyranny,[221] which ever surrounds all the boundaries of political liberty. I find no exception to this general axiom, that Every citizen ought to know when his actions are guilty or innocent. If censors, and arbitrary magistrates in general, are necessary in any government, it is due to the weakness of its constitution, and is foreign to the nature of a well organised government. More victims have been sacrificed to obscure tyranny by the uncertainty of their lot than by public and formal cruelty, for the latter revolts mens minds more than it abases them. The true tyrant always begins by mastering opinion, the precursor of courage; for the latter can only show itself in the clear light of truth, in the fire of passion, or in ignorance of danger.
