The consideration of these cases gives a clear idea of how a physician endeavours to fill up gaps in his knowledge of the character of the man, his heredity and environment, as well as his previous actions at various times in life when under the stress of emotion. It may be considered that such a weighing of circumstances will serve to excuse many genuine criminals who eminently deserve to be punished. This is, however, the assumption of the older generation who considered that if a man did a material wrong he must be punished for it. It is a heritage of the day, when even accidental killing was considered to demand some punishment. At the present time the tendency is rather to consider only the moral wrong, that is, to calculate responsibility only for such actions as are committed with due {305} deliberation, intention, and the knowledge of right and wrong as well as the freedom to perform the action. The old English legal opinion which declared a man responsible if he knows that what he is doing is wrong has now given way in most judicial proceedings to the principle that the man must not only know that he is doing wrong, but that he must also realise that he is free not to do that which he knows to be wrong. That is to say, if he feels himself compelled to the commission of crime, there is surely an impairment of responsibility. Such impulses to do wrong without adequate motive occur not infrequently among those whose mental condition is not perfectly normal, and this must always be taken into consideration in the ultimate decision as to their responsibility for their action. JAMES J. WALSH. {306} XXVII SUICIDES It is a very difficult problem at times to explain just how a suicide is due to mental alienation in a person whose intellectual powers appeared previously unimpaired, yet in most of the cases a knowledge of all the circumstances and of the individual himself would lead inevitably to this more charitable view. Most suicides are persons that have been recognised as paranoiacs and likely to do queer things for a long time beforehand. Indeed, some of the melancholic qualities on which the unfortunate impulse to self-murder depends are likely to have exhibited themselves in former generations. Not long since it was argued that the regular occurrence of a certain number of suicides every year--varying in various places, always on the increase, but evidently showing a definite relationship to certain local conditions --demonstrate that the human will is not free, since from a set of statistics one can foretell about how many cases of suicide would take place in a given city during the next year. As a matter of fact, suicides are not in possession of free will as a rule, but are the victims of circumstances and are unable to resist external influences.
