Excerpt from Principles and Methods of Orthodontics: An Introductory Study of the Art for Students and Practitioners of Dentistry Orthodontics as a Science - As a science it is closely related to many Of the medical sciences, the basis Of which is biology, the science Of life Life, that strange, unknown something which flies through the Viewless air, flashes through the ocean's depths, blushes in the petals Of a rose, and mani fests itself in thousands Of marvellous forms - can science grasp, define, or explain it? In the present stage of our knowledge probably not completely; but it teaches us that all vital processes, including man and all his characteristics, as well as those Of all other species, are the result Of the interaction Of certain laws. TO define these laws, to test them in the crucible Of Observation and experiment, and then to express them in terms Of human experience - this is the mission Of science.
