"I don't believe in this world-sorrow."

In Chapter Two of A Room With a View, by E.M. Forster, Lucy Honeychurch encounters the older Mr. Emerson on her first outing in Florence after her arrival. Because of Mr. Emerson's philosophical bent, the conversation quickly turns to philosophy. Mr. Emerson delivers these wonderful lines ('George' is Mr. Emerson's son, a young man of Lucy's age):

In his ordinary voice, so that she scarcely realized he was quoting poetry, he said: '"From far, from eve and morning / And yon twelve-winded sky / The stuff of life to knit me / Blew hither: Here am I." George and I both know this, but why does it distress him? We know that we come from the winds, and that we shall return to them; that all life is perhaps a knot, a tangle, a blemish in the eternal smoothness. But why should this make us unhappy? Let us rather love one another, and work and rejoice. I don't believe in this world-sorrow.'

Mr. Emerson is quoting a poem from A.E. Housman's A Shropshire Lad. Later, when Reverend Beebe and Freddy visit Mr. Emerson and George when Mr. Emerson and George are moving into the villa on Summer Street, they see a pile of books, among which is A Shropshire Lad. Reverend Beebe says, "Never heard of it."  

Here is the whole poem:

From far, from eve and morning
And yon twelve-winded sky,
The stuff of life to knit me
Blew hither: Here am I.

Now--for a breath I tarry
Nor yet disperse apart
Take my hand quick and tell me,
What you have in your heart.

Speak now and I will answer;
How shall I help you, say;
Ere to the wind's twelve quarters
I take my endless way.
