Edwin Arlington Robinson - Modernities

Small knowledge have we that by knowledge met
May not some day be quaint as any told
In almagest or chronicle of old,
Whereat we smile because we are as yet
The last—though not the last who may forget
What cleavings and abrasions manifold
Have marked an armor that was never scrolled
Before for human glory and regret.

With infinite unseen enemies in the way
We have encountered the intangible,
To vanquish where our fathers, who fought well,
Scarce had assumed endurance for a day;
Yet we shall have our darkness, even as they,
And there shall be another tale to tell.

Edwin Arlington Robinson
