From this ignorance of how to distinguish dreams, and other strong fancies, from vision and sense, did arise the greatest part of the religion of the Gentiles in time past, that worshipped satyrs, fauns, nymphs, and the like; and nowadays the opinion that rude people have of fairies, ghosts, and goblins, and of the power of witches. For, as for witches, I think not that their witchcraft is any real power, but yet that they are justly punished for the false belief they have that they can do such mischief, joined with their purpose to do it if they can, their trade being nearer to a new religion than to a craft or science. And for fairies, and walking ghosts, the opinion of them has, I think, been on purpose either taught, or not confuted, to keep in credit the use of exorcism, of crosses, of holy water, and other such inventions of ghostly men. Nevertheless, there is no doubt but God can make unnatural apparitions: but that He does it so often as men need to fear such things more than they fear the stay, or change, of the course of Nature, which he also can stay, and change, is no point of Christian faith. But evil men, under pretext that God can do anything, are so bold as to say anything when it serves their turn, though they think it untrue; it is the part of a wise man to believe them no further than right reason makes that which they say appear credible. If this superstitious fear of spirits were taken away, and with it prognostics from dreams, false prophecies, and many other things depending thereon, by which crafty ambitious persons abuse the simple people, men would be would be much more fitted than they are for civil obedience.
And this ought to be the work of the schools, but they rather nourish such doctrine. For (not knowing what imagination, or the senses are) what they receive, they teach: some saying that imaginations rise of themselves, and have no cause; others that they rise most commonly from the will; and that good thoughts are blown (inspired) into a man by God, and evil thoughts, by the Devil; or that good thoughts are poured (infused) into a man by God, and evil ones by the Devil. Some say the senses receive the species of things, and deliver them to the common sense; and the common sense delivers them over to the fancy, and the fancy to the memory, and the memory to the judgement, like handing of things from one to another, with many words making nothing understood.
The imagination that is raised in man (or any other creature endued with the faculty of imagining) by words, or other voluntary signs, is that we generally call understanding, and is common to man and beast. For a dog by custom will understand the call or the rating of his master; and so will many other beasts. That understanding which is peculiar to man is the understanding not only his will, but his conceptions and thoughts, by the sequel and contexture of the names of things into affirmations, negations, and other forms of speech: and of this kind of understanding I shall speak hereafter.

CHAPTER III OF THE CONSEQUENCE OR TRAIN OF IMAGINATIONS
BY CONSEQUENCE, OR TRAIN OF THOUGHTS, I UNDERSTAND THAT SUCCESSION of one thought to another which is called, to distinguish it from discourse in words, mental discourse.
When a man thinketh on anything whatsoever, his next thought after is not altogether so casual as it seems to be. Not every thought to every thought succeeds indifferently. But as we have no imagination, whereof we have not formerly had sense, in whole or in parts; so we have no transition from one imagination to another, whereof we never had the like before in our senses. The reason whereof is this. All fancies are motions within us, relics 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 coming again to take place and be predominant, the latter followeth, by coherence of the matter moved, in 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 pass in time that in the imagining of anything, there is no certainty what we shall imagine next; only this is certain, it shall be something that succeeded the same before, at one time or another.
This train of thoughts, or mental discourse, is of two sorts. The first is unguided, without design, and inconstant; wherein there is no passionate thought to govern and direct those that follow to itself 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 only without company, but also without care of anything; though even then their thoughts are as busy as at other times, but without harmony; as the sound which a lute out of tune would yield 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 dependence of one thought upon another. For in a discourse of our present civil war, what could seem more impertinent than to ask, as one did, what was the value of a Roman penny? Yet the coherence to me was manifest enough. For the thought of the war introduced the thought of the delivering up the King to his enemies; the thought of that brought in the thought of the delivering up of Christ; and that again the thought of the 30 pence, which was the price of that treason: and thence easily followed that malicious question; and all this in a moment of time, for thought is quick.
The second is more constant, as being regulated by some desire and design. For the impression made by such things as we desire, or fear, is strong and permanent, or (if it cease for a time) of quick return: so strong it is sometimes as to hinder and break our sleep. From desire ariseth the thought of some means we have seen produce the like of that which we aim at; and from the thought of that, the thought of means to that mean; and so continually, till we come to some beginning within our own power. And because the end, by the greatness of the impression, comes often to mind, in case our thoughts begin to wander they are quickly again reduced into the way: which, observed by one of the seven wise men, made him give men this precept, which is now worn out: respice finem; that is to say, in all your actions, look often upon what you would have, as the thing that directs all your thoughts in the way to attain it.
The train of regulated thoughts is of two kinds: one, when of an effect imagined we seek the causes or means that produce it; and this is common to man and beast. The other is, when imagining anything whatsoever, we seek all the possible effects that can by it be produced; that is to say, we imagine what we can do with it when we have it. Of which I have not at any time seen any sign, but in man only; for this is a curiosity hardly incident to the nature of any living creature that has no other passion but sensual, such as are hunger, thirst, lust, and anger. In sum, the discourse of the mind, when it is governed by design, is nothing but seeking, or the faculty of invention, which the Latins call sagacitas, and solertia; a hunting out of the causes of some effect, present or past; or of the effects of some present or past cause. Sometimes a man seeks what he hath lost; and from that place, and time, wherein he misses it, his mind runs back, from place to place, and time to time, to find where and when he had it; that is to say, to find some certain and limited time and place in which to begin a method of seeking. Again, from thence, his thoughts run over the same places and times to find what action or other occasion might make him lose it. This we call remembrance, or calling to mind: The Latins call it reminiscentia, as it were a re-conning of our former actions.
Sometimes a man knows a place determinate, within the compass whereof he is to seek; and then his thoughts run over all the parts thereof in the same manner as one would sweep a room to find a jewel; or as a spaniel ranges the field till he find a scent; or as a man should run over the alphabet to start a rhyme.
Sometimes a man desires to know the event of an action; and then he thinketh of some like action past, and the events thereof one after another, supposing like events will follow like actions. As he that foresees what will become of a criminal re-cons what he has seen follow on the like crime before, having this order of thoughts; the crime, the officer, the prison, the judge, and the gallows.
