individual. Study, for instance, manslaughter in Italy, and, although
you will find it difficult to isolate one of the factors of criminality
from the network of the other circumstances and conditions that produce
it, yet there are such eloquent instances of the influence of racial
character, that it would be like denying the existence of daylight if
one tried to ignore the influence of the ethnical factor on
criminality.

In Italy there are two currents of criminality, two tendencies which are
almost diametrically opposed to one another. The crimes due to hot blood
and muscle grow in intensity from northern to southern Italy, while the
crimes against property increase from south to north. In northern Italy,
where movable property is more developed, the crime of theft assumes a
greater intensity, while crimes due to conditions of the blood are
decreasing on account of the lesser poverty and the resulting lesser
degeneration of the people. In the south, on the other hand, crimes
against property are less frequent and crimes of blood more frequent.
Still there also are in southern Italy certain cases where criminality
of the blood is less frequent, and you cannot explain this in any other
way than by the influence of racial character. If you take a
geographical map of manslaughter in Italy, you will see that from the
minimum, from Lombardy, Piedmont, and Venice, the intensity increases
until it reaches its maximum in the insular and peninsular extreme of
the south. But even there you will find certain cases in which
manslaughter shows a lesser intensity.

For instance, the province of Benevent is surrounded by other provinces
which show a maximum of crimes due to conditions of blood, while it
registers a smaller number. Naples, again, shows a considerably smaller
number of such cases than the provinces surrounding it, but it has a
