The X-files episode 4x05 - "The Field Where I Died" starts out with Mulder standing in a grassy field and reading some lines from a poem, thus:

...at times I almost dream
I, too, have spent a life the sages' way,
And tread once more familiar paths. Perchance
I perished in an arrogant self-reliance
Ages ago; and in that act, a prayer
For one more chance went up so earnest, so
Instinct with better light let in by death,
That life was blotted out-not so completely
But scattered wrecks enough of it remain,
Dim memories, as now, when once more seems
The goal in sight again...

This turns out to be a quote from a very long (several thousand lines) poem by Robert Browning called Paracelsus. The original passage that Mulder reads is quoted below:

For me, I estimate their works and them
So rightly, that at times I almost dream
I too have spent a life the sages' way.
And tread once more familiar paths. Perchance
I perished in an arrogant self-reliance
Ages ago; and in that act, a prayer
For one more chance went up so earnest, so
Instinct with better light led in by death,
That life was blotted out--not so completely
But scattered wrecks enough of it remain,
Dim memories, as now, when once more seems
The goal in sight again. All which, indeed,
Is foolish, and only means--the flesh I wear,
The earth I tread, are not more clear to me
Than my belief, explained to you or no.
