John Blades on A Guidebook to Learning: For the Lifelong Pursuit of Wisdom (1986), by Mortimer J. Adler, and the author's writing process, at The Chicago Tribune. [link fixed -ed.]
"Having just published [book] No. 39, Adler seems to have refined the art of writing books to a mathematical science. As he explains his working method:
"'I go to Aspen every summer and write one in 14 or 15 days. I deliver it to the publisher on Sept. 1, and it comes out the next March.'
"The 84-year-old author/philosopher doesn`t want the process to sound too mechanical, however.
"'You have to understand,' he says, 'that I`ve been working on the book all year before I sit down to write it. I`ve got my notes organized in folders for each chapter, and the writing goes very quickly. It`s much the best way to write a book.'"
