Doubt is the father of invention.
by George William Russell
WHEN twilight flutters the mountains over,
The faery lights from the earth unfold:
And over the caves enchanted hover
The giant heroes and gods of old.
The bird of æther its flaming pinions
Waves over earth the whole night long:
The stars drop down in their blue dominions
To hymn together their choral song.
The child of earth in his heart grows burning,
Mad for the night and the deep unknown;
His alien flame in a dream returning
Seats itself on the ancient throne.
When twilight over the mountains fluttered,
And night with its starry millions came,
I too had dreams: the songs I have uttered
Come from this heart that was touched by the flame.
