r the defect is an abnormal impulse, or a normal impulse
abnormally strong, or an abnormally weak or defective inhibition, the
condition is hereditary, and such defectives propagate their kind.

It has been shown that they are more fertile than any other classes
because of the very defect that makes them a danger to society.

The defective restraint that allows them to commit offences against
person and property, also allows their procreative impulse unrestrained
activity.

Defectives, therefore, are not only fertile, but they propagate their
kind, and a few examples will serve to show to some extent the
fertility, and to an enormous extent the hereditary tendencies, of the
unfit.
