And this, again, is the reason why Lombroso's criticisms on my description of occasional criminals are lacking in force. He says, as Benedikt said at the Congress at Rome, that all criminals are criminals by birth, so that there is no such thing as an occasional criminal, in the sense of a _*normal_ individual casually launched into crime. But I have not, any more than Garofalo, drawn such a picture of the occasional criminal, for as a matter of fact I have said precisely the opposite, as indeed Lombroso himself acknowledges a little further on (ii. 422), <p 43>namely, that between the born and the occasional criminal there is only a difference of degree and modality, as in all the criminal classes. To cite a few details of criminal psychology, it may be stated that of the two physiological conditions of crime, moral insensibility and improvidence, occasional crime is especially due to the latter, and inborn and habitual crime to the former. With the born criminal it is, above all, the lack or the weakness of moral sense which fails to withstand crime, whereas with the occasional criminal the moral sense is almost normal, but inability to realise beforehand the consequences of his act causes him to yield to external influences. Every man, however pure and honest he may be, is conscious now and then of a transitory notion of some dishonest or criminal action. But with the honest man, exactly because he is physically and morally normal, this notion of crime, which simultaneously summons up the idea of its grievous consequences, glances off the surface of the normal conscience, and is a mere flash without the thunder. With the man who is less normal and has less forethought, the notion dwells, resists the weak repulsion of a not too vigorous moral sense, and finally prevails; for, as Victor Hugo says, ``Face to face with duty, to hesitate is to be lost.''[11] [11] For instance, I will recall a fact which Morel has related of himself, how one day, as he was crossing a bridge in Paris, he saw a working-man gazing into the water, and a homicidal idea flashed across his mind, so that he had to hurry away, for fear of yielding to the temptation to throw the man into the water. Again, there is the case of Humboldt's nurse, who was attacked one day by the temptation to kill her charge, and ran with him to his mother in order to avoid a <p 44>disaster. Brierre de Boismont also tells us of a learned man who, at the sight of a picture in a public gallery, was tempted to cut the canvas, and ran away from his impulse to crime. <p 44> The criminal of passion is one who is strong enough to resist ordinary temptations of no exceptional force, to which the occasional criminal would yield, but who does not resist psychological storms which indeed are sometimes actually irresistible.
