Nosce Teipsum: The Wit or Understanding

The WIT, the pupill of the Soule's cleare eye,
And in man's world, the onely shining starre;
Lookes in the mirror of the Fantasie,
Where all the gatherings of the Senses are.

From thence this power the shapes of things abstracts,
And them within her passiue part receiues;
Which are enlightned by that part which acts,
And so the formes of single things perceiues.

But after, by discoursing to and fro,
Anticipating, and comparing things;
She doth all vniversall natures know,
And all effects into their causes brings.
