anti-social acts which some sections of the community regard as major, while others regard them as minor, or even, in some cases, as not anti-social at all. The only convenient test we can apply is the strength of the social reaction—provided we are dealing with an act which is definitely anti-social, injuring recognized rights, and not merely an unusual or disgusting act.6 When an anti-social act meets with a reaction of social indignation which is fairly universal and permanent, it may be regarded as a crime coming under the jurisdiction of the law. If opinion varies, if a considerable section of the community revolt against the punishment of the alleged anti-social act, then we are not entitled to dignify it with the appellation of "crime." This is not an altogether sure or satisfactory criterion because there are frequently times and places, especially under the stimulation of some particular occurrence evoking an outburst of increased public emotion, when a section of the community succeeds by its noisy vigour in creating the impression that it voices the universal will. But, on the whole, it works out justly. Ethical standards differ in different places at different times. They are, indeed, always changing. Therefore, in regard to all matters which belong to the sphere of what we commonly call morals, there are in every community some who approve of a given act, others who disapprove of it, yet others who regard it with indifference. In such a shifting sphere we cannot legislate with the certainty of carrying the whole community with us, nor can we properly introduce the word "crime," which ought to indicate only an action of so gravely anti-social nature that there can be no possibility of doubt about it.
It is, however, important to understand the marked national differences in the reaction to these slightly or dubiously anti-social acts, for such differences rest on ancient tradition, and are to some extent the expression of the genius of a people, though they are not the absolutely immutable product of racial constitution, and, within limits, they
