Quote by George Box
For the theory-practice iteration to work, the scientist must be, as it were, mentally ambidextrous; fascinated equally on the one hand by possible meanings, theories, and tentative models to be induced from data and the practical reality of the real world, and on the other with the factual implications deducible from tentative theories, models and hypotheses.
"Science and Statistics" in the Journal of the American Statistical Association, Vol. 71, No. 356. (Dec., 1976), pages 791-799, on page 792.
