" And for the matter, or substance of the invisible agents, so fancied; they could not by natural cogitation, fall upon any other conceit, but that it was the same with that of the soul of man; and that the soul of man, was of the same substance, with that which appeareth in a dream, to one that sleepeth; or in a looking-glass, to one that is awake; which, men not knowing that such apparitions are nothing else but creatures of the fancy, think to be real, and external substances; and therefore call them ghosts; as the Latins called them imagines, and umbræ; and thought them spirits, that is, thin aërial bodies; and those invisible agents, which they feared, to be like them; save that they appear, and vanish when they please. But the opinion that such spirits were incorporeal, or immaterial, could never enter into the mind of any man by nature; because, though men may put together words of contradictory signification, as spirit, and incorporeal ; yet they can never have the imagination of any thing answering to them: and therefore, men that by their own meditation, arrive to the acknowledgment of one infinite, omnipotent, and eternal God, chose rather to confess he is incomprehensible, and above their understanding, than to define his nature by spirit incorporeal, and then confess their definition to be unintelligible: or if they give him such a title, it is not dogmatically, with intention to make the divine nature understood; but piously, to honour him with attributes, of significations, as remote as they can from the grossness of bodies visible. Then, for the way by which they think these invisible agents wrought their effects; that is to say, what immediate causes they used, in bringing things to pass, men that know not what it is that we call causing, that is, almost all men, have no other rule to guess by, but by observing, and remembering what they have seen to precede the like effect at some other time, or times before, without seeing between the antecedent and subsequent event, any dependence or connexion at all: and therefore from the like things past, they expect the like things to come; and hope for good or evil luck, superstitiously, from things that have no part at all in the causing of it: as the Athenians did for their war at Lepanto, demand another Phormio; the Pompeian faction for their war in Africa, another Scipio; and others have done in diverse other occasions since. In like manner they attribute their fortune to a stander by, to a lucky or unlucky place, to words spoken, especially if the name of God be amongst them; as charming and conjuring, the liturgy of witches; insomuch as to believe, they have power to turn a stone into bread, bread into a man, or any thing into any thing.
