We have only to vibrate the unused cells of the brain to bring forth primitive savagery. Take the action of a mob—let a vibratory wave of passion be set up in the unused cells of the brain and the entity knows no law but primitive force. Fear is for the time forgotten in the lust for blood. This is the explanation of the so-called bravery of the soldier in time of battle. Although fear dominates him before the clash of arms is reached, yet the moment he meets his antagonist the primitive lust for blood overcomes his fear and he becomes once more a primeval savage and fights to the death. The rationale of this is, that environment and mode of thought has put in vibration and attuned certain cells of the brain, by which he establishes communication with some reservoir of primitive savage vibration in the universe, and all the wild impulses of primeval instinct rush into and dominate him. The forgotten “vices” of our ancestors, apparently repeated from generation to generation, mean no more than this, as we have suggested heretofore; environment and its engendered mode of thought simply fitting the brain as a receiver for the reception of specific vibrations. We treat as criminals those who should be really treated for disease. We are responsible for the slum conditions in our cities and country which set up the brain attunement that calls forth these vibrations of ancestral vices. This is HOW the slums breed vice and crime. And it is in this direction we should put forth our efforts to reform the criminal. Are we not responsible for our criminals? We most assuredly are. We are responsible for these slum conditions and environments which create and bring into play these specific brain cells and cell vibrations. We say “Natural born criminals.” Not always. They are made so by environment. If the money spent in the effort to reform the vicious and criminal was applied to cleansing the slums and changing man’s environment, it would greatly reduce the necessity for jails, reform schools and asylums. We should enact laws to enable us to begin with the child in the public schools—compulsory if necessary. Not only educating, but seeing that they were properly clothed and housed and fed, and removed from their vicious surroundings, parents or guardians. In fact, we are the real criminals who permit such a thing as a crime producing slum or a “poor quarter.” The state can easily afford to do this in order to do away with the so-called vicious element or criminal class.
