The scheme that I am trying to present can perhaps best be summarized by a concrete instance. You can teach the deformities of rickets in one of two ways: one is to describe knock-knee, its cause, mechanical production and treatment, and then do the same for bow legs and coxa vara, which is a good way and the usual one. The other way is to teach about bone, its growth and ossification, to tell of bone disturbances, the most frequent of which is a certain disturbance of ossification called rickets; that this process causes softening, and that bending thus occurs according to the mechanical influences in the case, perhaps in one direction, perhaps in another; that you may have an inward, outward or forward deformity of the leg; that you must bring up ossification to normal by diet and hygiene, and not operate until this has happened. Meanwhile, you would treat by braces or manipulation, and thus you would link up rickets with other disturbances of ossification, achondroplasia and the like. In the latter method I believe that the man will have received more education than in the former. Education, In its derivation, means drawing out. It seems to me sometimes as if we had gone on the assumption that it meant putting in. These suggesions are offered in all modesty—merely as suggestions.
