INFINITY. This Quality manifests in a strong realization of the grand, the majestic, the vast, the illimitable, the infinite, the eternal, the absolute, the omnipotent, the omnipresent, the omniscient. It is the realizing sense of The Great. Those in whom it is large are impressed by the sublime, the majestic, the grand, in nature or in thought and conception. Niagara; the great work of the architect; the thunder-storm; the giant redwood of California; the ocean; or the thoughts of Infinity, alike appeal to the one in whom this Quality is large. If Reverence be large, the trend of Infinity will be toward religious ideas--the greatness of God. If the intellectual faculties be in the ascendency, Infinity will lead to high conceptions of Space, Nature, the Infinite. If Ideality be large, Infinity will incline toward the grand and great in art. If Constructiveness be well developed, Infinity will impel to the creation of great works, enterprises, buildings, schemes, or what not. Infinity influences everything in the direction of largeness and greatness. This Quality manifests in outer form on the side of the head, about midway between forehead and back-head, and about midway between "top and bottom" of that part of the head which contains the brain (see group figure). It is back of Ideality, and in front of Cautiousness; below Optimism and above Acquisitiveness, on the side of the head where the upward curve begins. HUMOR. This Quality manifests in a strong appreciation of the ludicrous, humorous, ironical, facetious, and raillery. Spurzheim says: "Those who write like Voltaire, Rabelais, Piron, Sterne, Rabener, Wieland, and all who are fond of jest, raillery, ridicule, irony, and comical conceptions, have the upper and outer parts of the forehead immediately before Beauty (Ideality) of considerable size." Combe says: "I have found in the manifestations of those whose Wit (Mirthfulness) predominates over Causality (Logic) a striking love of the purely ludicrous; their great delight being to heap absurd and incongruous ideas together; extract laughter out of every object; and enjoy the mirth their sallies created; and therefore agree with Spurzheim that the sentiment of the ludicrous is its primitive function." Those in whom it is very large are apt to be regarded as trifling and undignified, and people often lack respect for them. Those in whom it is weak are apt to be over-serious and dreary. A sense of humor is valuable in many ways, among which is its influence in letting us see the silly side of much pretentious nonsense which might otherwise deceive our reason and judgment. Many a solemn and dignified fallacy or error can best be attacked through a laugh and a realization of its absurdity. This Quality manifests outer form on the upper and lateral part of the forehead (see group figure). It is just before Ideality and just below Imitation. When large it gives a square and prominent shape to this part of the forehead. CHAPTER XII
