Nosce Teipsum: The Imagination or Common Sense

And yet these porters, which all things admit,
Themselues perceiue not, nor discerne the things;
One common power doth in the forehead sit,
Which all their proper formes together brings.

For all those nerues, which spirits of Sence doe beare,
And to those outward organs spreading goe;
Vnited are, as in a center there,
And there this power those sundry formes doth know.

Those outward organs present things receiue,
This inward Sense doth absent things retaine;
Yet straight transmits all formes shee doth perceiue,
Vnto a higher region of the braine.
