The relative absence of this element entirely or proportionately unfits the individual for these mental processes requiring delicacy and acuteness. He may possess a well-balanced organization as to temperament and cerebral development, but without the element of delicate quality he will be utterly incapable of those mental processes requiring delicate shades of thought. [Illustration: Sol Smith Russell--Quality Responsive.] The individual who unites the elements of strong and delicate quality will exhibit both power and fineness. He will be able to display more versatility of talent than the individual possessing the element of strength or delicacy alone. Those persons who have displayed great intelligence coupled with brilliancy, have uniformly united both of these elements. The element of _Responsiveness_ depends upon a certain sensitiveness of texture, resembling the resonance of a well tuned musical instrument, and a certain harmonious adjustment of parts which renders the individual capable of receiving a mental impression promptly and responding to its action. Persons possessing this quality have such delicate sympathy of the entire organization that the mental processes are exceedingly rapid, and the physical manifestations are equally prompt. The movements of the body are quick, the brain is active, the eye bright, intelligent and keen sighted, the expression of the face vivacious, the voice musical, the speech rapid, and the individual often anticipates the thought of those with whom he converses; if you hesitate on a word he will instantly supply it. Such persons are keenly sensitive to surrounding circumstances, easily impressed, and the entire organization seems to vibrate in unison with the impressions made upon it. It is not uncommon to find this condition mistaken by observers for the nervous temperament of the pathological classification. The true distinction lies in the fact that the latter is a diseased condition, resulting in a super-sensitiveness of the nervous system, while responsive quality exists in perfect health, and is a perfectly normal condition of a character frequently resulting in great advantage to the individual, and absolutely essential in many vocations. It is indispensable to the musician, the artist, the poet, etc., and I depend upon it in estimating the capacity of my subjects for various professions and trades, especially those involving the fine arts, literature, and many of the departments of merchandising.
