In a critical essay, Jean-Francois Lyotard writes of words as being "things," sentences are "events," and thought is "art." He states that "the space-time-matter of language is made perceptible, visible, by writing. Kosuth's work is a meditation on writing." Lyotard "compares Kosuth's visual works with the square letters of the Torah. These letters are also texts, but they are waiting for their accents, their vowels, their punctuation, their intonation, their putting into practice." -- Source of annotation: Marvin or Ruth Sackner.
