The way to be liberated from the constraining effects of any medium is to develop a perspective on it — how it works and what it does. Being illiterate in the processes of any medium (language) leaves one at the mercy of those who control it. The new media — these new languages — then are among the most important "subjects" to be studied in the interests of survival. But they must be studied in a new way if they are to be understood, they must be studied as mediators of perception. Indeed, for any "subject" or "discipline" to be understood it must be studied this way.
