From Robert Louis Stevenson’s essay “The Books Which Have Influenced Me”:
The most influential books, and the truest in their influence, are works of fiction. They do not pin the reader to a dogma, which he must afterwards discover to be inexact; they do not teach him a lesson, which he must afterwards unlearn. They repeat, they rearrange, they clarify the lessons of life; they disengage us from ourselves, they constrain us to the acquaintance of others; and they show us the web of experience, not as we can see it for ourselves, but with a singular change–that monstrous, consuming ego of ours being, for the nonce, struck out. To be so, they must be reasonably true to the human comedy; and any work that is so serves the turn of instruction. But the course of our education is answered best by those poems and romances where we breathe a magnanimous atmosphere of thought and meet generous and pious characters.
