Where biological defects of the individual are the cause of dependence, we have just implied that, unless these defects are relatively superficial, the scientific policy for treating these classes of defective individuals would be that of segregation in institutions. The feeble-minded, the chronic insane, the chronic epileptic, and other hopelessly defective persons, in other words, should be permanently kept in institutions where tender and humane care should be provided, but in such a way that they will not reproduce their kind and burden future generations. The policy of segregating the hopelessly defective is one of the most scientifically approved policies of modern philanthropy. In this way, to a certain extent, the reproduction of unfit elements in society might be lessened, and the spread of degeneracy checked. In the case of slightly defective adults, such as the congenitally deaf and the congenitally blind, it is difficult to say exactly what the policy should be. It would seem that many of these persons may be relatively adjusted to free social life, although if they marry and have offspring we know, if their defect is congenital, that a certain proportion of the offspring, according to Mendel's law, will inherit the defect. In the case of those individuals whose dependence is due to psychological defects, or defective character, it is evident that we have a different problem. Here, in general, the wise policy would seem to be, not to segregate, but to overcome the defective character. Psychological defects, we know, are much more frequently acquired than biological defects and much more easily remedied. The work of scientific philanthropy in dealing with this class of individuals must be, therefore, a work of remedying defects in individual character. This is, perhaps, best done through personal relations between the dependent person and those who may help him. Defective character is, on the whole, therefore, best remedied by such means as education, religious influences, friendly visiting, and the like. The class of dependents whose condition is due to defective character may be on the whole, therefore, best treated outside of institutions, and probably better through voluntary private charity than through public relief systems. There remains another class of dependents whose condition is not due either to biological nor to psychological defects in themselves, but to faulty social and industrial conditions. For these, the best method of treatment consists in remedying the faulty conditions or in removing them, if possible, from them. This means that, in many cases, society must provide pensions, insurance against accident and sickness, legislation to check social abuses, and, above all, proper facilities for education. Here comes in the need of child-labor legislation, of better housing, of industrial insurance, of industrial education, and the like.
