sing all useless intermeddling of the State
in the sexual life of individuals by the aid of unjustifiable
regulations, as well as all intervention in the natural sexual
requirements of man (in marriage, etc.), when no individual or social
interest is injured. What is much more difficult, is to prevent the
pressure of sexual sympathies and antipathies, and especially of
amorous passions in politics.

=7. Venereal Disease.=--There is need for a great combat with venereal
disease and pathological corruptions of the sexual appetite. (Vide
Chapters VIII, XIII and XIV.) Sexual criminals should be treated
conjointly with the pathology of the sexual appetite, and in the same
manner; for it is nearly always a question of anomalies of the human
brain, which are impossible to improve or eliminate by punishment or
other penal measures.

For the present, medical and administrative measures of restriction,
undertaken by society against dangerous and degenerate individuals in
the sexual domain, are the only possible remedy. We should also
endeavor in the future to prevent such individuals from breeding and
suppress the causes of blastophthoria, by the aid of our second
postulate.

=8. The Conflict of Human Races.=--There remains a last postulate,
extremely arduous and serious, which we have already mentioned. How is
our Aryan race and its civilization to guard against the danger of
being passively invaded and exterminated by the alarming fecundity of
other human races? One must be blind not to recognize this danger. To
estimate it at its proper value, it is not enough to put all "savages"
and "barbarians" into one basket and all "civilized" into the other.
The question is far more complicated than this. Many savage and
semi-savage races become rapidly extinct on account of their
comparative sterility. Europeans have introduced among them so much
alcohol, venereal disease and other plagues, that they promptly perish
from want of the power of resistance. This is the case with the
Weddas, the Todas, the Redskins of North America, the Australian
aboriginees, Malays and many others.

The question presents itself in another aspect with regard to negroes,
who are very resistant and extremely prolific, and everywhere adapt
themselves to civilized customs. But those who believe that negroes
are capable of _acquiring_ a higher civilization without undergoing a
phylogenetic cerebral transformation for a hundred thousand years, are
Utopians
