Desire We Past Illusions To Recall

Desire we past illusions to recall?
To reinstate wild Fancy, would we hide
Truths whose thick veil Science has drawn aside?
No, let this Age, high as she may, install
In her esteem the thirst that wrought man's fall,
The universe is infinitely wide;
And conquering Reason, if self-glorified,
Can nowhere move uncrossed by some new wall
Or gulf of mystery, which thou alone,
Imaginative Faith! canst overleap,
In progress toward the fount of Love, the throne
Of Power whose ministers the records keep
Of periods fixed, and laws established, less
Flesh to exalt than prove its nothingness.
