In addition to prostitutes and ordinary offenders, who constitute the larger part of female criminality, there exists a small number of born criminals of the female sex, who are more ferocious and terrible even than the male criminal of the same type. The criminality of this class of women develops on the same foundation of epilepsy and moral insanity. The physical characters are those peculiar to the male born criminal--projecting ears, strabismus, anomalies of dentition, and abnormal conformation of the skull, brain, etc.; in addition, an absence of feminine traits. In voice, structure of the pelvis, distribution of hair, etc., she tends to resemble the opposite sex and to lose all the instincts peculiar to her own. From this brief description it may be gathered that this work on the female offender owes much of its interest to the light it throws on the normal woman. It is true that it casts doubt on many of the postulates of feminism; but, on the other hand, it lays stress on and exalts the many invaluable qualities characteristic of the female sex. The preface to the work concludes with the following remarks: "Not one of the conclusions drawn from the history and examination of woman can justify the tyranny of which she has been and is still a victim, from the laws of savage peoples, which forbade her to eat meat and the flesh of the cocoanut, to those modern restrictions, which shut her out from the advantages of higher education and prevent her from exercising certain professions for which she is qualified. These ridiculous, cruel, and tyrannical prohibitions have certainly been largely instrumental in maintaining or, worse still, increasing her present state of inferiority and permitting her exploitation by the other sex. The very praises, not always sincere, alas, heaped on the docile victim, are often intended more as a preparation for further sacrifices than as an honour or reward." IV _Political Crime (Delitto Politico)_ (In Collaboration with Rodolfo Laschi) The law of inertia governs nature. Every organism tends to adhere indefinitely to the same mode of life and will not change unless forced to do so. In the depths of the ocean, where existence, comparatively speaking, is uniform and undisturbed, we still find organisms allied to the species of pre-historic epochs. Those stars and suns, which are outside the sphere of action of other worlds, continue eternally their vertiginous gyrations in the trajectories assigned to them at the beginning of all things. Every progress in nature is the result of a struggle between the tendency to immobility, manifested by misoneism, or the hatred of novelty, and a foreign force which seeks to conquer this tendency.
