=No Special Inheritable Crime-Factor.--=The main difficulty in trying to find a hereditary basis for crime lies in the multiplicity of things crime may be. The individual impulsions which lead to certain offenses may be utterly different from those which conduce to others. Undoubtedly many inborn tendencies which are perfectly normal or neutral in themselves may be warped by circumstances into the commission of what are classified as crimes. The moral man may have the same desire for a thing that the criminal does, but when he finds that this desire can only be gratified by injury to others, he inhibits it because of his repugnance to such injury. The criminal makes no such inhibition. In general, crime means an offense of some kind against person, property or state. But a biological analysis of it, could it be made, would require among other things knowledge of crime in terms of motive or lack of motive, whether the act was intended to benefit the perpetrator, some other person, or even the race or state; whether the offense was one of dishonesty, of cupidity, of lust, or of violence against another. As a matter of fact no satisfactory classification of crime can be made since so many factors enter and in such varying degrees. Most classifications made in our legal codes are a hodge-podge based on a mixture of motive on the part of the participant, degree of turpitude involved, nature and extent of the injury inflicted, and the object against which the offense was perpetrated, whether an individual, society or the state. Moreover, it must not be forgotten that in many instances what was crime in the past is no longer so, and vice versa many things which are regarded as criminal to-day were not considered so in the past. So the futility of seeking a specific inherent propensity for "crime" is manifest. How, for instance, in terms of hereditary determiners shall we draw the fine lines of distinction among those who bribe legislators and legal officials, those who are avaricious and dishonest in the world of trade, and those who are wilfully obtuse in providing proper safeguards for employees?
