These Passions have a free commanding might, And divers actions in our life do breed; For all acts done without true Reason's light, Do from the Passion of the Sense proceed. But sith the Brain doth lodge these powers of Sense, How makes it, in the Heart those passions spring? The mutual love, the kind intelligence 'Twixt heart and brain, this Sympathy doth bring. From the kind heat, which in the heart doth reign, The spirits of Life do their beginning take! These spirits of Life ascending to the brain, When they come there, the spirits of Sense do make These spirits of Sense in Phantasy's high court, Judge of the Forms of Objects, ill or well! And so, they send a good or ill report Down to the heart, where all Affections dwell. If the report be good; it causeth love! And longing hope! and well assured joy! If it be ill; then doth it hatred move! And trembling fear! and vexing griefs annoy! Yet were these natural affections good (For they which want them, blocks or devils be!); If Reason in her first perfection stood, That she might Nature's Passions rectify. [Sidenote: The motion of Life.] Besides, another Motive Power doth rise Out of the heart: from whose pure blood do spring The Vital Spirits, which born in arteries, Continual motion to all parts do bring. [Sidenote: The local motion.] This makes the pulses beat, and lungs respire, This holds the sinews, like a bridle's reins; And makes the body to advance, retire, To turn or stop, as she them slacks or strains! Thus the Soul tunes the Body's instrument; These harmonies She makes with Life and Sense: The organs fit, are by the Body lent; But th'actions flow from the Soul's influence. [Sidenote: The Intellectual Powers of the Soul.] But now I have a Will, yet want a Wit, To express the workings of the Wit and Will; Which, though their root be to the body knit, Use not the Body, when they use their skill. These powers the nature of the Soul declare, For to Man's Soul, these only proper be! For on the earth, no other wights there are, Which have these heavenly powers, but only [Sidenote: The Wit or Understanding.] The Wit (the pupil of the Soul's clear eye! And in Man's world, th'only shining star!) Looks in the Mirror of the Phantasy, Where all the gatherings of the senses are From thence this Power, the Shapes of things abstracts, And them within her _Passive_ part receives; Which are enlightened by that part which _Acts_, And so the Forms of single things perceives.
