The line of demarcation between sanity and insanity, like that between
health and disease, is sometimes so nebulous that it becomes exceedingly difficult
to decide where the one ends and the other begins. It is not a matter of wonder,
therefore, that differences of opinion should arise in this connection, particularly
when the question of responsibility is raised. There has been not a little
discussion as to the existence of so-called moral insanity as an entity, but
despite the objections to its recognition, the disorder has retained its place
in mental nosology. Perhaps the term moral imbecility would be preferable.
The affection must be looked on as a degenerative one of congenital origin.
The general intellectual functions may be unimpaired, while the moral sense
is lost in greater or lesser degree.
