I could quote Luhmann on this as well, who thought that "without writing one cannot think," But there is nothing peculiarly "Luhmannian" about this idea. Isaac Asimov is said to have said "Writing to me is simply thinking through my fingers." And, to give one other example, E. B. White (of "Strunk and White" fame) claimed that "writing is one way to go about thinking." In other words, writing is thinking. And since I do almost all my significant writing in ConnectedText these days, it might be called my "writing environment."

Asimov, for the uninitiated, is one of the most important figures in science fiction and is often regarded as one of the “big three” authors, along with Robert A Heinlein and Arthur C Clarke. Together they helped bring about the so-called “golden age” of science fiction in the mid-20th century.
