Faust — Part 1 by Johann Wolfgang von Goethe

…MEPHISTOPHELES
I to the upper ranks do not belong;
Yet if, by me companion’d, thou
Thy steps through life forthwith wilt take;
Upon the spot myself I’ll make
Thy comrade;— Should it suit thy need,
I am thy servant, am thy slave indeed!

FAUST
And how must I thy services repay?

MEPHISTOPHELES
Thereto thou lengthen’d respite hast!

FAUST
No! No!
The devil is an egoist I know:
And, for Heaven’s sake, ’tis not his way
Kindness to any one to show.
Let the condition plainly be exprest!
Such a domestic is a dangerous guest.

MEPHISTOPHELES
I’ll pledge myself to be thy servant here,
Still at thy back alert and prompt to be;
But when together yonder we appear,
Then shalt thou do the same for me.

FAUST
But small concern I feel for yonder world;
Hast thou this system into ruin hurl’d,
Another may arise the void to fill.
This earth the fountain whence my pleasures flow,
This sun doth daily shine upon my woe,
And if this world I must forego,
Let happen then,—what can and will.
I to this theme will close mine ears,
If men hereafter hate and love,
And if there be in yonder spheres
A depth below or height above.

MEPHISTOPHELES
In this mood thou mayst venture it. But make
The compact! I at once will undertake
To charm thee with mine arts. I’ll give thee more
Than mortal eye hath e’er beheld before.
