Human perception is literally incarnation.
What we call art would seem to be specialist artifacts for enhancing human perception.
The poet, the artist, the sleuth, whoever sharpens our perception tends to antisocial; rarely 'well adjusted,' he cannot go along with currents and trends.
Typography tended to alter language from a means of perception and exploration to a portable commodity.
Language always preserves a play or figure/ground relation between experience, and perception and its replay in expression.
The artist is a person who is expert in the training of perception.
The greatest propaganda in the world is our mother tongue, that is what we learn as children, and which we learn unconsciously. That shapes our perceptions for life. That is propaganda at its most extreme form.
All media exist to invest our lives with artificial perceptions and arbitrary values.
