Sickness must therefore be examined by a thorough scrutiny of the elements that make up morbid changes that exist in the likeness of drug symptoms. To the extent that drugs in provings upon healthy men have brought out symptoms on animal ultimates must we study sickness with the hope of adjusting remedies to sickness in man under the law of similars. Ultimate symptoms, function symptoms, sensorium symptoms and mind symptoms are all useful and none should e overlooked. The idea of sickness in man must be formed from the idea of sickness perceived in our Materia Medica. As we perceive the nature of sickness in a drug image, so must we perceive the nature of the sickness in a human being to be healed.
Therefore our idea of pathology must be adjusted to such a Materia Medica as we possess, and it must be discovered where in these are similar in order to heal the sick. The totality of the symptoms written out carefully is all that we know of the internal nature of sickness. Then the proper administration of the similar remedy will constitute the art of healing.
