Just as philosophy seeks a full rounded development of the psyche in its approach to spiritual self-realization, so does it seek a full adequate treatment in its approach to the problem of curing sickness. It recognizes that even if a sickness began with evil thoughts or wrong feelings or disharmonious courses of action, these have already worked their way into and affected the physical body and brought about harmful changes in it, either causing its organs to work badly, or introducing poisons into its blood system, or even creating malignant growths in its tissues. Therefore physical means must also be used to treat these physical conditions, as well as the spiritual means to get rid of wrong thoughts and discordant feelings. Both methods should be applied together to make an adequate treatment. Consequently philosophy does not, like Christian Science, deny the utility or necessity of ordinary medical treatment. On the contrary, it welcomes such treatment, provided it is not narrow-minded, materialistic, or selfishly concerned more with fees than with healing.
