This mundus tenebrosus, this shaddowy world of Mankind, is sunk into Night; there is not a Field without its Spirits, nor a City without its Daemons, and the Lunaticks speak Prophesies while the Wise men fall into the Pitte. We are all in the Dark, one with another. And, as the Inke stains the Paper on which it is spilt and slowly spreads to Blot out the Characters, so the Contagion of darkness and malefaction grows apace until all becomes unrecognizable. Thus it was with the Witches who were tryed by Swimming not long before, since once the Prosecution had commenced no Stop could be put to the raving Women who came forward: the number of Afflicted and Accused began to encrease and, upon Examination, more confess'd themselves guilty of Crimes than were suspected of. And so it went, till the Evil revealed was so great that it threatened to bring all into Confusion.And yet in the way of that Philosophie much cryed up in London and elsewhere, there are those like Sir Chris. who speak only of what is Rational and what is Demonstrated, of Propriety and Plainness. Religion Not Mysterious is their Motto, but if they would wish the Godhead to be Reasonable why was it that when Adam heard that Voice in the Garden he was afraid unto Death? The Mysteries must become easy and familiar, it is said, and it has now reached such a Pitch that there are those who wish to bring their mathematicall Calculations into Morality, viz. the Quantity of Publick Good produced by any Agent is a compound Ratio of his Benevolence and Abilities, and such like Excrement. They build Edifices which they call Systems by laying their Foundacions in the Air and, when they think they are come to sollid Ground, the Building disappears and the Architects tumble down from the Clowds. Men that are fixed upon matter, experiment, secondary causes and the like have forgot there is such a thing in the World which they cannot see nor touch nor measure: it is the Praecipice into which they will surely fall.
