Better, surely, not to pretend to calculate the incalculable, not to pretend that there is an Archimedean point outside the world whence everything is measurable and alterable; better to use in each context the methods that seem to fit it best, that give the (pragmatically) best results; to resist the temptations of Procrustes; above all to distinguish what is isolable, classifiable and capable of objective study, and sometimes of precise measurement and manipulation, from the most permanent, ubiquitous, inescapable, intimately present features of our world, which, if anything, are overfamiliar, so that their ‘inexorable’ pressure, being too much with us, is scarcely felt, hardly noticed, and cannot conceivably be observed in perspective, be an object of study.
