hundred times greater than where both parents are adventitiously deaf and have no deaf relatives. This is pretty conclusive proof that it is only the congenital defects which are transmissible, but these are so highly transmissible that they may express themselves in pauperism from generation to generation. The marriage of all persons in whom there is an hereditary taint of feeble-mindedness, insanity, epilepsy, and the like ought, therefore, to be forbidden by law. But unless these defective classes were segregated in institutions, the only result of this might be to increase illegitimacy; therefore, any step in eradicating degeneracy and pauperism must look to the isolation and custodial care through life of the hopelessly defective classes. All this gives point to our conclusion that poverty and pauperism have roots which are quite independent of defects in economic conditions, and that, until heredity itself can be controlled, we cannot expect to eliminate poverty entirely. Proposed Remedies for Poverty and Pauperism.--The scientific remedies for poverty and pauperism, that is, the scientific methods of dealing with the various dependent classes and of preventing their existence, now form the subject-matter of a great independent science, the science of philanthropy, which, as we have already seen, may be considered a branch of applied sociology. We have not room in this book to discuss adequately these remedies, but we may call the attention of the student again to the vast literature existing upon the subject, and may point out the trend of modern scientific philanthropy in developing scientific methods for removing the causes of dependence and of preventing the existence of the various dependent classes. As we have already seen, poverty is an economic expression of biological or psychological defects of the individual on the one hand, and of a faulty social and industrial organization on the other hand. This implies that the remedies must be along the lines of the biological and psychological adjustment of the individual and of the correction of the faults in social organization.
