if there is such a specific weakness, it is possible it has a period of maximum intensity, and if that should be only a brief phase in development—let us say at adolescence—it might turn out to be much more to the advantage of humanity to contrive protective legislation over the dangerous years. I argue to establish no view in these matters beyond a view that at present we know very little.
Not only do ignorance and doubt bar our way to anything more than a pious wish to eliminate criminality and drunkenness in a systematic manner, but even the popular belief in ruthless suppression whenever there is “madness in the family” will not stand an intelligent scrutiny. The man in the street thinks madness is a fixed and definite thing, as distinct from sanity as black is from white. He is always exasperated at the hesitation of doctors when in a judicial capacity he demands: “Is this man mad or isn’t he?” But a very little reading of alienists will dissolve this clear assurance. Here again it seems possible that we have a number of states that we are led to believe are simple because they are gathered together under the generic word “madness,” but which may represent a considerable variety of induced and curable and non-inheritable states on the one hand and of innate and incurable and heritable mental disproportions on the other.
