We don’t see the world. We have an artificial image of it in our minds. A fact that should be brought out much more. The meaning of things perceived would shift immensely.
If, after all, we only have an image in our head that is generated by impulses from our senses, then it is not far-fetched, indeed almost probable, that if we dampen down our five senses we can experience the qualities of the world quite differently. How can one not investigate this fact if one really wants to know more about the world?
