It is plain from what has gone before that I have not wished to deny the direct influence of the physical environment upon man. Indeed, it is a fact which the whole world has observed. According to many persons, then—and a number of scientific researches have proved it—a high degree of criminality against persons proceeds from a hot temperature, while a low temperature, on the other hand, leads to many crimes against property. This implies not only that the kind of crime is different in hot countries from that in cold, but also that the change of the seasons with their variations in temperature have the corresponding effects. I will not fatigue the reader by citing an unlimited number of examples to prove that the exceptions to this rule are very numerous. We cannot find a greater number of crimes against persons and a smaller number of crimes against property with each degree nearer the equator. If this were the case dishonesty would be unknown at the equator, and everyone there would be very violent. There are countries which, though in the same latitude, are very different as to crime, as there are others, much alike as to crime though situated far from each other, etc., etc. [118] The adherents of the theory of the “physical environment” explain these exceptions by saying that they are caused by the “social environment.” By so doing they recognize that the latter may entirely alter and even annihilate the influence of the former. Let us concern ourselves rather with the different kinds of crime, and investigate the influence which the physical environment exercises upon it. In the first place, as to the assertion that cold increases the number of crimes against property it is unnecessary to speak at length, for nearly all authors are agreed that not physical but economic causes come into play here. Cold increases men’s needs; they must have warmer clothing and a well heated dwelling. But it is clear that all this is no motive for stealing. For the person of means gets what he wants with his own money. It is the present social organization that, during the severe weather, does not permit people to provide for the needs that are more numerous then, for the opportunity to work is more often lacking in winter than in summer.
