For example, having established by his purely quantitative methods that the Gross National Product of a country has risen by, say, five per cent, the economist-turned-econometrician is unwilling, and generally unable, to face the question of whether this is to be taken as a good thing or a bad thing. He would lose all his certainties if he even entertained such a question: growth of GNP must be a good thing, irrespective of what has grown and who, if anyone, has benefited.
