In the inorganic kingdom we have evidences of an influence which cannot be denominated either chemical or mechanical. The communication of magnetical and electrical properties to iron by mere contact with another body, without the introduction of any change of form or of composition, either of the iron itself or of the imparting body, is an example of this. NOw, to influences of this kind the term dynamical has been applied, and several pharmacologists have employed it to indicate those influences of medicines over the organism which are ascribable to neither mechanical nor chemical causes.-PEREIRAS Materia Medica.
Hahnemann says, “by far the greater number of diseases are of a dynamic nature,” and further, “that disease can only be removed by dynamic means”. Again he says, “diseases will not , out of deference to our stupidity, cease to be dynamic aberrations which our spiritual existence undergoes in its mode of feeling and acting-that is to say, immaterial changes in the state of health”. Again he says that it is an established fact that, “with the exception of those diseases brought on by the introduction of indigestible or hurtful substances into alimentary canal, and other organs, those produced by foreign bodies penetrating the skin, etc., there does not exist a single disease that can have a material principle for it cause.”-J.T. TEMPLE, M.D., 1868.
