Menitculture or the A-B-C or True Living (1896) - Horace Fletcher - Bog

Medical science had struggled for centuries with the repression and amelioration of physical disease before it discovered the possibility of prevention by killing the germ. Mental science pursued the same course of attempted repression in this country until quite recently it was found that mental afflictions have germs also, and it naturally follows that any who are interested in the subject should try to discover, not only the germs themselves, but methods of getting rid of them.
