Read the following poem:

Others abide our question. Thou art free.
We ask and ask-thou smilest and art still,
Out-topping knowledge.
For the loftiest hill,
Who to the stars uncrowns his majesty,
Planting his steadfast footsteps in the sea,
Making the heaven of heavens his
dwelling place,
Spares but the cloudy border of his base
To the foiled searching of mortality.

by Matthew Arnold
