Therefore it is far from being exact to assert that the positive criminal school reduces crime to a purely and exclusively anthropological phenomenon. As a matter of fact, this school has always from the beginning maintained that crime is the effect of anthropological, physical, and social conditions, which evolve it by their simultaneous and inseparable operation. And if inquiries into biological conditions have been more abundant and more conspicuous by their novelty, this in no way contradicts the fundamental conclusion of criminal sociology. That being stated, we have still to examine the relative value of these three classes of conditions in the natural evolution of crime. It seems to me that this question is generally stated inaccurately, and also that it cannot be answered absolutely, and in a word. It is generally stated inaccurately; because they who think, for instance, that crime is nothing else than a purely and exclusively social phenomenon in the evolution of which the organic and psychical anomalies of the criminal have had no part, ignore more or less consciously the universal correlation of natural forces, and forget that, in regard to any phenomenon whatsoever, it is impossible to set an absolute limit to the network of its causes, immediate and remote, direct and indirect. To put this question in an arbitrary sense would <p 56>be like asking if a mammal is the product of its lungs, or its heart, or its stomach, or of vegetable constituents, or of the atmosphere; whereas each of these conditions, internal and external, is necessary to the life of the animal. In fact, if crime were the exclusive product of the social environment, how could one explain the familiar fact that in the same social environment, and in identical circumstances of poverty, abandonment, lack of education, sixty per cent. do not commit crimes, and, of the other forty, five prefer suicide, five go mad, five simply become beggars or tramps not dangerous to society, whilst the remaining twenty-five actually commit crimes? And amongst the latter, whilst some go no further than theft without violence, why do others commit theft with violence, and even kill their victim outright, before he offers resistance, or threatens them, or calls for help, and this with no other object than gain? The secondary differences of social condition, which may be observed even amongst the members of a single family, rotting in one of the slums of our great towns, or amongst those who are surrounded by the temptations of money or power, or the like, are clearly not enough in themselves to explain the vast differences in the actions which grow out of them, varying from honesty under the greatest discouragement to suicide and murder.
