I feel such a difference between a philologist/linguist and a linguaphile as, say, a choreographer and a ballerina.
My view is that knowing languages is part of the process of becoming a cultured person.
Knowledge—like a nail—is made load-bearing by being driven in. If it's not driven deep enough, it will break when any weight is put upon it.
Language is present in a piece of work like the sea in a single drop.
He who knows other languages feels even closer to his own language.
Solely in the world of languages is the amateur of value. Well-intentioned sentences full of mistakes can still build bridges between people.
