"Why do so many ingenious theorists give fresh reasons every year for the decline of letter writing, and why do they assume, in derision of suffering humanity, that it has declined? They lament the lack of leisure, the lack of sentiment ... They talk of telegrams, and telephones, and postal cards, as if any discovery of science, any device of civilization, could eradicate from the human heart that passion for self-expression which is the impelling force of letters."
