Book II  The Book of the Traveller of the Worlds
 Canto III  The Glory and the Fall of Life Page 116

An uneven broad ascent now lured his feet.
Answering a greater Nature's troubled call
He crossed the limits of embodied Mind
And entered wide obscure disputed fields
Where all was doubt and change and nothing sure,
A world of search and toil without repose.
As one who meets the face of the Unknown,
A questioner with none to give reply,
Attracted to a problem never solved,
Always uncertain of the ground he trod,
Always drawn on to an inconstant goal
He travelled through a land peopled by doubts
In shifting confines on a quaking base.
In front he saw a boundary ever unreached
And thought himself at each step nearer now,--
A far retreating horizon of mirage.
A vagrancy was there that brooked no home,
A journey of countless paths without a close.
Nothing he found to satisfy his heart;
A tireless wandering sought and could not cease.
There life is the manifest Incalculable,
A movement of unquiet seas, a long
And venturous leap of spirit into Space,
A vexed disturbance in the eternal Calm,
An impulse and passion of the Infinite.
Assuming whatever shape her fancy wills,
Escaped from the restraint of settled forms
She has left the safety of the tried and known.
Unshepherded by the fear that walks through Time,
Undaunted by Fate that dogs and Chance that springs,
She accepts disaster as a common risk;
