All Fancies are Motions within us, reliques of those made in the Sense: And those motions that immediately succeeded one another in the sense, continue also together after Sense: In so much as the former comming again to take place, and be praedominant, the later followeth, by coherence of the matter moved, is such manner, as water upon a plain Table is drawn which way any one part of it is guided by the finger.

But because in sense, to one and the same thing perceived, sometimes one thing, sometimes another succeedeth, it comes to passe in time, that in the Imagining of any thing, there is no certainty what we shall Imagine next; Onely this is certain, it shall be something that succeeded the same before, at one time or another.
Trayne Of Thoughts Unguided This Trayne of Thoughts, or Mentall Discourse, is of two sorts.

The first is Unguided, Without Designee, and inconstant; Wherein there is no Passionate Thought, to govern and direct those that follow, to it self, as the end and scope of some desire, or other passion: In which case the thoughts are said to wander, and seem impertinent one to another, as in a Dream.

Such are Commonly the thoughts of men, that are not onely without company, but also without care of any thing; though even then their Thoughts are as busie as at other times, but without harmony; as the sound which a Lute out of tune would yeeld to any man; or in tune, to one that could not play.

And yet in this wild ranging of the mind, a man may oft-times perceive the way of it, and the dependance of one thought upon another.
