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.
