As a followup, consider this scenario. Say we had a large lecture hall full of people, who each speak different languages. There are about 6500 different languages spoken by humans, on the earth, so the lecture hall will have 6500 people in the audience.
What I will do is place a few objects on a table, center stage, and have each person tell me what these objects are. Since we have 6500 different languages there may be thousands of different noises/sound for each object. Verbal language and words are subjective and arbitrary. There is no universal sound for each thing. This is all learned and conditioned.
On the other hand, each person in the audience will see the same things on center stage. This is how they all express there objects in their native tongue. Visual is not learned but is part of a natural universal language, common to all humans. You can place any object in the field of vision and you will know it. This is true of all of us.
This universal nature is why visual is connected to logic and proof. This is independent of verbal language and opinions. Spoken language is more subjective and the various noises and sounds are arbitrary. This makes illusions possible, based on how you define things.
