Intelligence is the result of the radiation of magnetism from every object in the universe. Magnetism is radiated by different bodies in different degrees of intensity. Man is provided with seven distinct organs of sense, which receive and interpret these radiations. The lowest rate of vibration is received and interpreted by the sense of gender and the next stage by the sense of touch. Above that we have the senses of taste, hearing, sight, smell and clairvoyance. So that the human body is in reality a magnetic musical instrument of seven octaves, each octave constituting a separate sense and each sense subdivided into seven degrees. The radiation of magnetism from exterior objects strikes the human body in these different degrees of vibration and it is the ability of the body to receive these vibrations and of the brain to analyze them, which constitutes the intelligence of the individual. The absence of any organ of sense or the absence of any part of the brain needed in its analysis is accompanied by the corresponding absence or diminution of intelligence. Reasoning therefor from these premises it follows that by inspection of the organization of an individual and by careful examination of his organs of sense and brain capacity we are able to determine how much intelligence he possesses and in what direction it will be projected. When we study its development and its deterioration, its faculties and their manifestation, we amass a glittering pile of brilliant facts; we classify those facts, reduce them to rules to serve the needs of the human race, and we have the science of Phrenology; and when we apply those rules in the practical delineation of character, we have the Art. In regard to Phrenology being an exact science, I have shown you that the distinction must be drawn between the principles of the science and the results of their estimative application. The principles of the science are absolute. In his application of them the examiner is hampered by the frailties and fallibilities of the human intellect, just to the same extent that the skilled surgeon or the bright astronomer is subject to the same drawbacks. Would any sensible man decline the services of a skilled surgeon in the hour of need, because surgeons differ in judgment, or, in some cases, make mistakes. Astronomy is regarded as a wonderfully exact science because an eclipse can be computed one hundred years in advance to the fraction of a second, yet astronomers differ in regard to the distance of the sun from the earth to the trifling extent of six million miles. Shall we therefore reject astronomy?
