PHRENOLOGY is the science of intelligence. It is derived from two Greek words--_Phren_ intelligence _Logos_ "discourse" or science. But before we can properly understand this definition we must have a definition of the term "Science," which is about as often misused as any word I know. _Science_ is classified knowledge. The word itself in its etymology signifies what we _know_ about a particular subject. And whenever we learn two facts about any subject, and we differentiate and classify those two facts, we have a science of that subject. Thus we have the science of Astronomy, containing the classified facts that intelligent observers have learned concerning the stars. The science of Mathematics, a classification of knowledge concerning numbers, and the science of Phrenology, which simply means the facts that intelligent observers have collected concerning intelligence, classified and reduced to rules to serve a practical purpose. Before I leave this term "Science," I wish to draw a distinction between a science and an art. The science is the classified knowledge; the art is the process of turning that knowledge to practical account. The science of Astronomy never discovered a star, the science of Arithmetic never computed the value of a fraction. The sciences are merely icebergs of cold, hard facts piled up in crystallized principles and rules. Art is the warm, living application of these principles and rules to serve the needs of mankind. The art of Astronomy, with the assistance of its handmaiden, the art of Mathematics, astounds the world with its achievements, and holds in one hand the balances with which it weighs the sun, and in the other the chain with which it surveys the distance to the Pleiades. So with the Science and Art of Phrenology. The science is as absolute as Mathematics. In its principles there are no fallacies. To its rules there are absolutely no exceptions. The Art of Phrenology, on the other hand, is estimative, and the results of its application will depend on the graces, the gifts and the abilities of him who seeks to apply it. As we have brilliant astronomers and poor astronomers, as we have correct mathematicians and incorrect ones, so we may have phrenologists whose discoveries and whose workmanship may command the admiration of the world, those whose talents are of the order of mediocrity, and those who blunder on all occasions. You have had Phrenology defined to you as the Science of Intelligence, and you naturally ask for a definition of intelligence itself.
