In Monday's episode, Mortimer describes a conversation in which his friend Graham Greene almost convinces him of the truth of Christianity. He quotes from Robert Browning's poem Bishop Blougram's Apology. Green and Mortimer share the attitudes of the two characters in the poem--the bishop and his dinner guest, with their parallel belief and unbelief.
I've put the parts quoted by Mortimer in bold in this piece of Browning's much longer poem:
And now what are we? unbelievers both,
Calm and complete, determinately fixed
To-day, to-morrow and for ever, pray?
You’ll guarantee me that? Not so, I think!
In no wise! all we’ve gained is, that belief,
As unbelief before, shakes us by fits,
Confounds us like its predecessor. Where’s
The gain? how can we guard our unbelief,
Make it bear fruit to us?—the problem here.
Just when we are safest, there’s a sunset-touch,
A fancy from a flower-bell, some one’s death,
A chorus-ending from Euripides,—
And that’s enough for fifty hopes and fears
As old and new at once as nature’s self,
To rap and knock and enter in our soul,
Take hands and dance there, a fantastic ring,
Round the ancient idol, on his base again,—
The grand Perhaps! We look on helplessly.
There the old misgivings, crooked questions are—
This good God,—what he could do, if he would,
Would, if he could—then must have done long since:
If so, when, where and how? some way must be,—
Once feel about, and soon or late you hit
Some sense, in which it might be, after all.
Why not, “The Way, the Truth, the Life?”
—That way
Over the mountain, which who stands upon
Is apt to doubt if it be meant for a road;
While, if he views it from the waste itself,
Up goes the line there, plain from base to brow,
Not vague, mistakeable! what’s a break or two
Seen from the unbroken desert either side?
And then (to bring in fresh philosophy)
What if the breaks themselves should prove at last
The most consummate of contrivances
To train a man’s eye, teach him what is faith?
And so we stumble at truth’s very test!
All we have gained then by our unbelief
Is a life of doubt diversified by faith,
For one of faith diversified by doubt:
We called the chess-board white,—we call it black.
“Well,” you rejoin, “the end’s no worse, at least;
We’ve reason for both colours on the board:
Why not confess then, where I drop the faith
And you the doubt, that I’m as right as you?”
