Facile and fertile literary brains
Faithfully and religiously eschewed [eschew = avoid; shun]
Fallen into the convenient oblivion of the waste-basket
Fanatical and dangerous excesses
Far off and incredibly remote
Fastidious correctness of form
Fate had turned and twisted a thousand ways
Fed by many currents from the long stream of human experience
Feigning a virtuous indignation
Fertility of argumentative resource
