The Rational Corporeal Motions, being the purest, most free, and so most active, have great power over the Sensitive; as to perswade, or command them to obedience: As for example, When a man is studying about some Inventions of Poetical Fancies, or the like; though the Sensitive Corporeal Motions, in the Sensitive Organs, desire to desist from patterning of Objects, and would move towards sleep; yet the Rational will not suffer them, but causes them to work, viz. to write, or to read, or do some other Labour: Also, when the Rational Mind is merry, it will cause the Leggs to dance, the Organs of the Voice to sing, the Mouth to speak, to eat, to drink, and the like: If the Mind moves to sadness, it causes the Eyes to weep, the Lungs to sigh, the Mouth to speak words of Complaint. Thus the Rational Corporeal Motions of the Mind, will occasion the Senses to watch, to work, or to sport and play. But mistake me not; for I do not mean, the Senses are bound to obey the Rational Designs; for, the Sensitive Corporeal Motions, have as much freedom of Self-moving, as the Rational: for, the Command of the Rational, and the Obedience of the Sensitive, is rather an Agreement, than a Constraint: for, in many cases, the Sensitive will not agree, and so not obey: also, in many cases, the Rational submits to the Sensitive: also, the Rational sometimes will be irregular; and, on the other side, sometimes the Sensitive will be irregular, and the Rational regular; and sometimes both irregular.
[CHAP. XVII. Of Human Appetites and Passions.]
The Sensitive Appetites, and the Rational Passions do so resemble each other, as they would puzzle the most wise Philosopher to distinguish them; and there is not only a Resemblance, but, for the most part, a sympathetical Agreement between the Appetites, and the Passions; which strong conjunction, doth often occasion disturbances to the whole life of Man; with endless Desires, unsatiable Appetites, violent
Passions, unquiet Humors, Grief, Pain, Sadness, Sickness, and the like; through which, Man seems to be more restless, than any other Creature: but, whether the cause be in the Manner, or Form of Man's Composition, or occasioned by some Irregularities; I will leave to those who are wiser than I, to judg. But this is to be noted, That the more Changes and Alterations the Rational and Sensitive Motions make, the more variety of Passions and Appetites the Man hath: also, the quicker the Motions are, the sharper Appetite, and the quicker Wit, Man hath. But, as all the Human Senses are not bound to one Organ; so all Knowledges are not bound to one Sense, no more than all the Parts of Matter to the composition of one particular Creature: but, by some of the Rational and Sensitive actions, we may perceive the difference of some of the Sensitive and Rational actions; as, Sensitive Pain, Rational Grief; Sensitive Pleasure, Rational delight; Sensitive Appetite, Rational Desire; which are sympathetical actions of the Rational and Sensitive Parts: Also, through sympathy, Rational Passions will occasion Sensitive Appetites; and Appetites, the like Passions.
[CHAP. XVIII. Of the Rational Actions of the Head and Heart of Human Creatures.]
As I formerly said, In every Figurative Part of a Human Creature, the Actions are different, according to the Property of their different Composers; so that the Motions of the Heart are different to the Motions of the Head, and of the other several Parts: but, as for the Motions of the Head, they are (in my Opinion) more after the manner of Emboss'd Figures; and those of the Heart, more after the manner of Flat Figures; like Painting, Printing, Engraving, &c. For, if we observe, the Thoughts in our Heads are different from the Thoughts in our Hearts. I only name these two Parts, by reason they seem to sympathize, or to agree, more particularly to each other's actions, than some of the other Parts of Human Creatures.
