And this gray spirit yearning in desire To follow knowledge like a sinking star, Beyond the utmost bound of human thought. - Alfred Tennyson

To follow knowledge like a sinking star, Beyond the utmost bound of human thought.

Let me go: take back thy gift:
Why should a man desire in any way
To vary from the kindly race of men,
Or pass beyond the goal of ordinance
Where all should pause, as is most meet for all?
...Why wilt thou ever scare me with thy tears,
And make me tremble lest a saying learnt,
In days far-off, on that dark earth, be true?
‘The Gods themselves cannot recall their gifts.’
- Tithonus

Sunset and evening star
And one clear call for me!
And may there be no moaning of the bar,
When I put out to sea,

But such a tide as moving seems asleep,
Too full for sound and foam,
When that which drew from out the boundless deep
Turns again home.

Twilight and evening bell,
And after that the dark!
And may there be no sadness of farewell,
When I embark;

For though from out our bourne of Time and Place
The flood may bear me far,
I hope to see my Pilot face to face
When I have crossed the bar.

And out of darkness came the hands that reach thro' nature, moulding men.
