Continuity in excess often manifests in "long-windedness," prosiness, boredom, prolixity and tiresomeness. When it is weak there is manifested a "flightiness," tendency to change, lack of concentration, attraction of the new, a shifting of base, change of mind, and general instability and lack of "stick-to-itiveness." This Quality manifests outer form on the centre line of the top back of the head, just below the crown (Self-Esteem) and just above Inhabitiveness (see group figure). Reference to the group figure will show that it is peculiar in shape, and forms a semi-circular arch over a part of the top-back head. When fully developed that part of the head is simply evenly rounded with swelling; when deficient it leaves a hollow, crescent shape, horns downward. In America we find the majority of people are weak in Continuity, while in certain other countries it is found largely developed in the majority of cases. This fact gives to Americans a benefit in certain directions and a weakness in others. Both Firmness and Continuity are manifested almost entirely in connection with the other Qualities, and are known almost altogether in that way. In themselves they have almost abstract nature. In determining character, they must be taken largely into consideration, because their influence on the other Qualities is very great. In fact they may be said to _determine_ the degree of _application_ of the other Qualities. CHAPTER XI THE MODIFICATIVE QUALITIES The sixth group is known as the Modificative Qualities (called by the phrenologists "The Self-Perfecting Group"), which is composed of the following particular Qualities. _Ideality_, _Infinity_ and _Humor_, respectively. This group manifests outer form in the region of the temples, and when large gives width to the sides of the fore part of the head (See Figure 7). IDEALITY. This Quality could well be called the "Artistic" quality of the mind. It manifests in a strong desire for the beautiful, the ideal, the elegant, the polished, the graceful, the refined. It is also closely connected with the phase of mental activity called "Imagination." Those in whom it is largely developed manifest the artistic taste and temperament, the love of art, beauty and the ideal, the poetic spirit, the love of the refined and choice--and a corresponding dislike for all opposed to these tastes and qualities.
