Teaching here isn't so bad. Once you accept as one of the ineluctable laws of nature that kids will continue to say "Silas Mariner" and "Ancient Marner" and "between you and I" and "mischievious" and that the administration will continue to use phrases like "egregious conduct" and "ethnic background" you can go on from there.
[S]cientists are not robotic inducing machines that infer structures of explanation only from regularities observed in natural phenomena (assuming, as I doubt, that such a style of reasoning could ever achieve success in principle). Scientists are human beings, immersed in culture, and struggling with all the curious tools of inference that mind permits […]. Culture can potentiate as well as constrain as Darwin's translation of Adam Smith's laissez-faire economic models into biology as the theory of natural selection. In any case, objective minds do not exist outside culture, so we must make the best of our ineluctable embedding.stephen jay gould
Political realism is aware of the moral significance of political action. It is also aware of the ineluctable tension between the moral command and the requirements of successful political action. And it is unwilling to gloss over and obliterate that tension and thus to obfuscate both the moral and the political issue by making it appear as though the stark facts of politics were morally more satisfying than they actually are, and the moral law less exacting than it actually is.hans morgenthau
Nothing endures, nothing is precise and certain (except the mind of a pedant), perfection is the mere repudiation of that ineluctable marginal inexactitude which is the mysterious inmost quality of Being. Being, indeed! – there is no being, but a universal becoming of individualities, and Plato turned his back os truth when he turned towards his museum of specific ideals.
