Man’s science is the culture of his heart;
And not to lose his plummet in the depths
Of nature, or the more profound of God.

The wisest on a level with the fool.
To fathom nature (ill attempted here!)
Past doubt is deep philosophy above;
Higher degrees in bliss archangels take,
As deeper learn’d; the deepest, learning still.
