FORE:For since the observance of some regular proportion between crime and punishment, whatever that proportion may be, constitutes the first principle of an[87] equitable code; and since the most important thing in public morality is a fixed penal estimate for every class of crime; it is above all things desirable that the law should always adhere to such proportion and estimate, by concerning itself solely with the crime and not with the criminal. The injury to the public is precisely the same whether a criminal has broken the law for the first time or for the thousandth and first; and to punish a man more severely for his second offence than for his first, because he has been punished before, is to cast aside all regard for that due proportion between crime and punishment which is after all the chief ingredient of retributive justice, and to inflict a penalty often altogether incommensurate with the injury inflicted on the public.It would be possible to distinguish a case of fraud from a grave fault, a grave fault from a light one, and this again from perfect innocence; then to affix to the first the penalties due for crimes of falsification; to the second lesser penalties, but with the loss of personal liberty; and, reserving for the last degree the free choice of the means of recovery, to deprive the third degree of such liberty, whilst leaving it to a mans creditors. But the distinction between grave and light should be fixed by the blind impartiality of the laws, not by the dangerous and arbitrary wisdom of a judge. The fixings of limits are as necessary in politics as in mathematics, equally in the measurement[219] of the public welfare as in the measurement of magnitudes.[68]
