Genius must be born, and never can be taught. - John Dryden

Dim as the borrowed beams of moons and stars
To lonely, weary, wandering travelers,
Is Reason to the soul; and, as on high
Those rolling fires discover but the sky,
Not light us here, so Reason's glimmering ray
Was lent, not to assure our doubtful way,
But guide us upward to a better day.

A Heroick Poem, truly such, is undoubtedly the greatest Work which the Soul of Man is capable to perform.
