According as the Motions of the Heart or Brain are, such Passions are produced.

The Eights in Musick, when they equal are,
If one be struck, the other seems to jarr:
So the Heart-strings, if equally all stretch'd,
Like those of Musick, Love from thence is fetch'd;
For when one's struck, the other moves just so,
And with delight as Evenly doth go.
