THREE:A few stories may be taken as illustrative of thousands to indicate the mischief and travesty of justice which arises from the neglect of this principle, and from the custom of making a legal inquiry into moral antecedents.Given the necessity of the aggregation of mankind, and given the covenants which necessarily result from the very opposition of private interests, a scale of offences may be traced, beginning with those which tend directly to the destruction of society, and ending with acts of the smallest possible injustice committed against individual members of it. Between these extremes are comprised all the actions opposed to the public welfare which are called crimes, and which by imperceptible degrees decrease in enormity from the highest to the lowest. If the infinite and obscure combinations of human actions admitted of mathematical treatment, there ought to be a corresponding scale of punishments, varying from the severest to the slightest penalty. If there were an exact and universal scale of crimes and punishments, we should have an approximate and general test by[199] which to gauge the degrees of tyranny and liberty in different governments, the relative state of the humanity or wickedness of different nations. But the wise legislator will rest satisfied with marking out the principal divisions in such a scale, so as not to invert their order, nor to affix to crimes of the first degree punishments due to those of the last.
