Original: (fr) Parce que la pratique est subjective, la théorie qui est toujours la théorie d’un objet, ne peut atteindre la réalité de cette pratique, ce qu’elle est en elle-même, sa subjectivité précisément, mais seulement se la représenter, de telle manière que cette représentation laisse hors d’elle l’être réel de la pratique, l’effectivité du faire. La théorie ne fait rien.
“Success is nothing more than a few simple disciplines, practiced every day.”

“A business man once stated that there is nothing so practical as a good theory.”

“The theory of the Text can coincide only with a practice of writing.”
Conclusion
From Work to Text (1971)
Context: The discourse on the Text should itself be nothing other than text, research, textual activity, since the Text is that social space which leaves no language safe, outside, nor any subject of the enunciation in position as judge, master, analyst, confessor, decoder. The theory of the Text can coincide only with a practice of writing.
