We learn mostly through our eyes. Every properly functioning human being transforms the visual signals that he receives from the outside into meaningful entities. Without the perceptual ordering of his sense responses into the image of things in space, man cannot orient himself, and without shaping his physical environment in accordance with these images, he cannot survive.

This reveals that learning through sight overshadows learning through any and all other senses, so no adjustment for error, incidents, or exceptions could lessen the impact of sight on the process of learning.

We do not think in words or numbers, but our mind thinks in pictures or natural forms and shapes present in the surrounding environment. To communicate facts, figures, and ideas, visual presentation is the most effective medium.
