How To Talk About Books You Have Not Read is a wonderful book by Pierre Bayard. The book can be read at two different levels as many books can. On one level it is a humorous book, a little like the book by Stephen Potter called One-Up-Manship, which has advice on how to impress people with one’s literary credentials even though one has never read the classics. Pierre Bayard, however, makes a very serious point - that no one will ever read all the books that they need to read or could read in their particular topic. It is far more important to know about a book and its core message, preferably in the author’s own words, and to understand how that book fits into the culture and relates to other books and concepts then not to know that a book existed.
Language creates reality, it does not describe it. That is one of the principles that has emerged from anthropology, linguistics and philosophy from authors as diverse as Ludwig Wittgenstein, John Searle and Benjamin Lee Whorf. Confusion about language and the meaning of the terms being used is one of the main causes of arguments, fruitless arguments, which disappear if everyone shares the same understanding of the terms being used.
