Eucatastrophe

“The Resurrection was the greatest ‘eucatastrophe’ possible in the greatest Fairy Story–and produces that essential emotion: Christian joy which produces tears because it is qualitatively so like sorrow, because it comes from those places where Joy and Sorrow are at one, reconciled, as selfishness and altruism are lost in Love.” -- J.R.R. Tolkien (The Letters of J. R. R. Tolkien, 1981)

A eucatastrophe is a sudden turn of events in a story which ensures that the protagonist 

does not meet some terrible, impending, and very plausible and probable doom.

The Power of Small Acts: Gandalf's Wisdom

“Saruman believes it is only great power that can hold evil in check, but that is not what I have found. It is the small everyday deeds of ordinary folk that keep the darkness at bay. Small acts of kindness and love. Why Bilbo Baggins? Perhaps because I am afraid, and he gives me courage.” 

On Fairy-Stories

Below is an extract from "On Fairy-Stories," an essay by J. R. R. Tolkien which discusses the fairy-story as a literary form. It was initially written for presentation by Tolkien as the Andrew Lang lecture at the University of St Andrews, Scotland, in 1939. I liked this extract:

Not long ago—incredible though it may seem—I heard a clerk of Oxenford declare that he “welcomed” the proximity of mass-production robot factories, and the roar of self-obstructive mechanical traffic, because it brought his university into “contact with real life.” He may have meant that the way men [sic] were living and working in the twentieth century was increasing in barbarity at an alarming rate, and that the loud demonstration of this in the streets of Oxford might serve as a warning that it is not possible to preserve for long an oasis of sanity in a desert of unreason by mere fences, without actual offensive action (practical and intellectual). 

I fear he did not. In any case the expression “real life” in this context seems to fall short of academic standards. The notion that motor-cars are more “alive” than, say, centaurs or dragons is curious; that they are more “real” than, say, horses is pathetically absurd. How real, how startlingly alive is a factory chimney compared with an elm-tree: poor obsolete thing, insubstantial dream of an escapist!
