Reasonableness is a matter of degree. Beliefs can be very reasonable (Japan exists), fairly reasonable (quarks exist), not unreasonable (there's intelligent life on other planets) or downright unreasonable (fairies exist).There's a scale of reasonableness, if you like, with very reasonable beliefs near the top and deeply unreasonable ones towards the bottom. Notice a belief can be very high up the scale, yet still be open to some doubt. And even when a belief is low down, we can still acknowledge the remote possibility it might be true.How reasonable is the belief that God exists? Atheists typically think it very unreasonable. Very low on the scale. But most religious people say it is at least not unreasonable (have you ever met a Christian who said 'Hey, belief in God is no more reasonable than belief in fairies, but I believe it anyway!'?) They think their belief is at least halfway up the scale of reasonableness.Now, that their belief is downright unreasonable might, in fact, be established empirically. If it turned out that not only is there no good evidence of an all-powerful, all-good God, there's also overwhelming evidence against (from millions of years of unimaginable and pointless animal suffering, including several mass extinctions - to thousands of children being crushed to death or buried alive in Pakistan earthquake, etc. etc. etc.) then it could be empirically confirmed that there's no God.Would this constitute a 'proof' that there's no God? Depends what you mean by 'proof'. Personally I think these sorts of consideration do establish beyond any reasonable doubt that there is no all-powerful all-good God. So we can, in this sense, prove there's no God.Yet all the people quoted in my last blog say you cannot 'scientifically' prove or disprove God's existence. If they mean prove beyond any doubt they are right. But then hardly anything is provable in that sense, not even the non-existence of fairies.

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.

Mind you, I cannot swear that my story is true. It may have been a dream; or worse, a symptom of some severe mental disorder. But I believe it is true. After all, how are we to know what things there are on earth? Strange monstrosities still exist, and foul, incredible perversions. Every war, each new geographical or scientific discovery, brings to light some new bit of ghastly evidence that the world is not altogether the same place we fondly imagine it to be. Sometimes peculiar incidents occur which hint of utter madness.How can we be sure that our smug conceptions of reality actually exist? To one man in a million dreadful knowledge is revealed, and the rest of us remain mercifully ignorant. There have been travelers who never came back, and research workers who disappeared. Some of those who did return were deemed mad because of what they told, and others sensibly concealed the wisdom that had so horribly been revealed. Blind as we are, we know a little of what lurks beneath our normal life. There have been tales of sea serpents and creatures of the deep; legends of dwarfs and giants; records of queer medical horrors and unnatural births. Stunted nightmares of men's personalities have blossomed into being under the awful stimulus of war, or pestilence, or famine. There have been cannibals, necrophiles, and ghouls; loathsome rites of worship and sacrifice; maniacal murders, and blasphemous crimes. When I think, then, of what I saw and heard, and compare it with certain other grotesque and unbelievable authenticities, I begin to fear for my reason.

I have long been of the Opinion, says he, that the Fire was a vast Blessing and the Plague likewise; it gave us Occasion to understand the Secrets of Nature which otherwise might have overwhelm'd us. (I busied my self with the right Order of the Draughts, and said nothing.) With what Firmness of Mind, Sir Chris. went on, did the People see their City devoured, and I can still remember how after the Plague and the Fire the Chearfulnesse soon returned to them: Forgetfulnesse is the great Mystery of Time.I remember, I said as I took a Chair opposite to him, how the Mobb applauded the Flames. I remember how they sang and danced by the Corses during the Contagion: that was not Chearfulnesse but Phrenzy. And I remember, also, the Rage and the Dying -These were the Accidents of Fortune, Nick, from which we have learned so much in this Generation.It was said, sir, that the Plague and the Fire were no Accidents but Substance, that they were the Signes of the Beast withinne. And Sir Chris. laughed at this.At which point Nat put his Face in: Do you call, sirs? Would you care for a Dish of Tea or some Wine?Some Tea, some Tea, cried Sir Chris. for the Fire gives me a terrible Thirst. But no, no, he continued when Nat had left the Room, you cannot assign the Causes of Plague or Fire to Sin. It was the negligence of Men that provoked those Disasters and for Negligence there is a Cure; only Terrour is the Hindrance.Terrour, I said softly, is the Lodestone of our Art.

It is one of the greatest Curses visited upon Mankind, he told me, that they shall fear where no Fear is: this astrological and superstitious Humour disarms men's Hearts, it breaks their Courage, it makes them help to bring such Calamities on themselves. Then he stopped short and looked at me, but my Measure was not yet fill'd up so I begg' d him to go on, go on. And he continued: First, they fancy that such ill Accidents must come to pass, and so they render themselves fit Subjects to be wrought upon; it is a Disgrace to the Reason and Honour of Mankind that every fantasticall Humourist can presume to interpret the Skies (here he grew Hot and put down his Dish) and to expound the Time and Seasons and Fates of Empires, assigning the Causes of Plagues and Fires to the Sins of Men or the Judgements of God. This weakens the Constancy of Humane Actions, and affects Men with Fears, Doubts, Irresolutions and Terrours.I was afraid of your Moving Picture, I said without thought, and that was why I left.It was only Clock-work, Nick.But what of the vast Machine of the World, in which Men move by Rote but in which nothing is free from Danger?Nature yields to the Froward and the Bold.It does not yield, it devours: You cannot master or manage Nature.But, Nick, our Age can at least take up the Rubbidge and lay the Foundacions: that is why we must study the principles of Nature, for they are our best Draught.No, sir, you must study the Humours and Natures of Men: they are corrupt, and therefore your best Guides to understand Corrupcion.The things of the Earth must be understood by the sentient Faculties, not by the Understanding. There was a Silence between us now until Sir Chris. says, Is your Boy in the Kitchin? I am mighty Hungry.
