A bit of Quintilian:
“To hunt down everything ever said even by the most despised writer means either wretched pedantry or ostentatious vanity. It suppresses and smothers talents which would be better kept free for other matters. For anyone who goes carefully through every page, whether worth reading or not, may just as well deploy his energies on old wives’ tales.” Bk 1.8
Don’t be satisfied with small, gray pearls, he says. Hold out for the big stuff. Hold out for the pearl of the world.
