I recently came across early modern poet Sir John Davies's poems on the immortality of the soul, in his Nosce Teipsum. It is an interesting example of early modern philosophical argument in verse form, so I thought I would provide a sample.

The Passions of Sense

"BUT though the apprehensiue power doe pause,
The motiue vertue then begins to moue ;
Which in the heart below doth Passions cause,
Joy, griefe, and feare, and hope, and hate, and loue.

These passions haue a free commanding might,
And diuers actions in our life doe breed;
For, all acts done without true Reason's light,
Doe from the passion of the Sense proceed.

But sith the braine doth lodge the powers of Sense,
How makes it in the heart those passions spring ?
The mutuall loue, the kind intelligence
Twixt heart and braine, this sympathy doth bring.

From the kind heat, which in the heart doth raigne,
The spirits of life doe their begining take;
These spirits of life ascending to the braine,
When they come there, the spirits of Sense do make.

These spirits of Sense, in Fantasie's High Court,
Judge of the formes of obiects, ill or well;
And so they send a good or ill report
Downe to the heart, where all affections dwell.

If the report bee good, it causeth loue,
And longing hope, and well-assured ioy:
If it bee ill, then doth it hatred moue,
And trembling feare, and vexing griefe's annoy.

Yet were these naturall affections good:
(For they which want them, blockes or deuils be)
If Reason in her first perfection stood,
That she might Nature's passions rectifie.
