A.E. Housman, The Application of Thought to Textual Criticism
(address to the Classical Association, August 4, 1921):
Most men are rather stupid, and most of those who are not stupid are, consequently, rather vain; and it hardly possible to step aside from the pursuit of truth without falling a victim either to your stupidity or else to your vanity. Stupidity will then attach you to received opinions, and you will stick in the mud; or vanity will set you hunting for novelty, and you will find mare's nests. Added to these snares and hindrances there are the various forms of partisanship: sectarianism, which handcuffs you to your own school and teachers and associates, and patriotism, which handcuffs you to your own country. Patriotism has a great name as a virtue, and in civic matters, at the present stage of the world's history, it possibly still does more good than harm; but in the sphere of intellect it is an unmitigated nuisance.
