The first repetition is on p. 61, which is excerpted below. The second repetition is on p. 63; its context is essentially the same as that of the second repetition in the first edition. Box's widely cited book "Statistics for Experimenters" (co-authored with William Hunter) does not include the aphorism in its first edition (published in 1978). The second edition (published in 2005; co-authored with William Hunter and J. Stuart Hunter) includes the aphorism three times: on p. 208, p. 384, and p. 440. On p. 440, the relevant sentence is this: "The most that can be expected from any model is that it can supply a useful approximation to reality: All models are wrong; some models are useful". In addition to stating the aphorism verbatim, Box sometimes stated the essence of the aphorism with different words. One example is from 1978, while Box was President of the American Statistical Association. At the annual meeting of the Association, Box delivered his Presidential Address, wherein he stated this: "Models, of course, are never true, but fortunately it is only necessary that they be useful". There have been varied discussions about the aphorism. A selection from those discussions is presented below. In 1983, the statisticians Peter McCullagh and John Nelder published their much-cited book on generalized linear models. The book includes a brief discussion of the aphorism (though without citing Box). A second edition of the book, published in 1989, contains a very similar discussion of the aphorism. The discussion from the first edition is as follows. In 1995, the statistician Sir David Cox commented as follows. In 1996, an Applied Statistician's Creed was proposed. The Creed includes, in its core part, the aphorism. In 2002, K. P. Burnham and D. R. Anderson published their much-cited book on statistical model selection. The book states the following. The statistician J. Michael Steele has commented on the aphorism as follows. In 2008, the statistician Andrew Gelman responded to that, saying in particular the following. In 2013, the philosopher of science Peter Truran published an essay related to the aphorism. The essay notes, in particular, the following. Truran's essay further notes that Newton's theory of gravitation has been supplanted by Einstein's theory of relativity and yet Newton's theory remains generally "empirically adequate".
