“Most men are rather stupid, and most of those who are not stupid are, consequently, rather vain; and it is 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.”
