This view has been opposed in various quarters on the ground that Lombroso, in other parts of his leading work, explains criminality as an atavistic reversion to primitive human types, and that, consequently, in accordance with the same principle of equivalent values, the type of the epileptic must also be identical with that of primitive man. This conclusion being an impossible one, it is held that Lombroso’s whole chain of reasoning is false. But Lombroso invokes the principle of equivalent values in relation, not to qualitative, but to quantitative, relations. His opponents have just as little right to use this principle for a _reductio ad absurdum_ as Lombroso himself had to speak of “identity” instead merely of “analogy.” It must be admitted that the criminal and the epileptic temperaments are very closely allied, that epileptics provide a disproportionately large contingent to the world of crime, and that it is quite possible that genetic relationships exist between the born criminal and the epileptic. It may well happen that when a mother suffering from nervous or mental disorder becomes pregnant, the brain and the whole organism of her child will be poorly nourished, and will, therefore, not develop normally. The child may have its development arrested at an earlier and more primitive stage, corresponding to the type of a remote ancestor, and, at the same time, these nutritive disturbances may lead to disturbances in the formation of the nerve elements, whereby the child is rendered epileptic throughout its life. The child is thus born an epileptic, and according to the nature of the arrest of development from which it suffers, it may happen that it is incapable of a normal development of the life of feeling, or it may be incapable of acquiring a normal power of resistance to anti-social impulses. It then becomes a criminal, and is, at the same time, an epileptic, with atavistic characteristics. These features may thus be united at the root, as we may see in every idiot asylum, and, unfortunately, also in numerous instances in every prison.
