"“There is seeing in the physical sense of light transmitted through the eyes and seeing in an internal mental sense. Clarity of physical seeing is called visual acuity and can be objectively measured. Clarity of internal seeing is often called ‘wisdom’, ‘genius’ or ‘insight’, and cannot be mechanically gained or measured. Somewhere within each person these two kinds of seeing meet. At this junction, between physical and mental vision, imagination can activate both visual acuity and internal seeing.”"
