Once it is recognized that productive thinking in any area of cognition is perceptual thinking, the central function of art in general education will become evident.

The arts are neglected because they are based on perception, and perception is disdained because it is not assumed to involve thought.

Climbing is a heroic liberating act; and height spontaneously symbolizes things of high value, be it in the value of worldly power or of spirituality. To rise in an elevator, balloon, or airplane is to experience being liberated from weight, sublimated, invested with superhuman abilities. In addition, to rise from the earth is to approach the realm of light and overview. Therefore the negative overcoming of weight is at the same time the positive achievement of enlightenment and an unobstructed outlook.
