—My criticism of what has gone before will be limited to some principal points only. First. The author dodges the question when he includes under economic conditions poverty only, and this in the very limited sense of the lack of the absolute necessities. He who writes upon the connection between crime and economic conditions must analyze the whole present economic system, and not stop with one of the consequences of that system, the poverty in which the proletarians find themselves. Consequently Garofalo’s whole argument, tending to show that the bourgeoisie have a great part in the crimes against property, is beside the mark, for capitalism results in great uncertainty of existence for the bourgeoisie also. It is then quite comprehensible that this class should be guilty of crimes of this kind. According to Fornasari di Verce, however, the Italian statistics show that the well-to-do class take less part in crime than the poor. According to him 13% of all those convicted in 1887 were well-to-do, a class which, roughly speaking, forms 40% of the whole population. (See also Colajanni, “La Sociologia Criminale”, II, pp. 536 ff.) In consequence of this arbitrary restriction of the subject the author’s remarks are of little value. But aside from this there are still serious charges to be made against his manner of treating the subject. Second. The assertion of Garofalo that in general in our present society he who wishes to work can find work, is not worth combating in a serious book. To say that machinery does not every day make some workers unnecessary, that there are no industrial crises causing an enormous amount of involuntary unemployment, is conclusive proof that one does not know the present mode of production. The existence of a group of the population, the so-called lower proletariat (“bas-prolétariat”, “Lumpen-proletariat”) cannot be a natural phenomenon, since it has not been always and everywhere present; it is strictly bound up with certain modes of production. Third. As I have had occasion to show already in more than one place, the increase of crimes against persons during periods of prosperity has a very great, though indirect, connection with economic conditions. Fourth. That poverty in the strict sense of the word is not the sole cause of economic criminality, that cupidity plays also an important rôle, I do not wish to deny. Only, this cupidity is not an innate quality of man, present everywhere and always, but is awakened only under certain economic conditions. This is especially the case in our present society.
