My first pillar of Science<\/a> is that it is based on repeatable observations.\u00a0 In order to see how Christianity measures up, we need to examine whether it is based on observations, and whether it is repeatable.<\/p>\n Observations ultimately boil down to sense-data experienced by individual human beings.\u00a0 You can’t go directly from observations to theories without a certain amount of interpretation, but that’s true in Science too.\u00a0 In order to be regarded as accurate, theories need to be based on empirical evidence, which has to be specific enough to prove that that theory is accurate, rather than just some similar theory in the class of theories.\u00a0 Not all aspects of the theory need to be directly confirmed to be accepted (otherwise we could never use a theory to make predictions in new circumstances).\u00a0 So long as the untested aspects of the theory are closely bound to aspects of the theory which are testable, the theory has a whole can be considered empirical.<\/p>\n Now Christian theology is empirical in this sense: that most of the core doctrines are the most reasonable explanations of certain ordinary sense-data<\/em> reported by actual human beings.\u00a0 By “ordinary” sense data, I mean things which appear to be interactions with the normal shared waking world, rather than sense-data seen in dreams or hullucinations, experienced in an altered state of consciousness.\u00a0 (If Christianity is true, God does sometimes communicates using dreams and such, but the most important information was not given primarily in this way.)\u00a0 The experiences might be “visions” in the sense of revealing truths about things in Heaven, but they are not “visions” in the sense of being subjective and intangible features of a single individual’s private experiences.<\/p>\n Here’s an example.\u00a0 One of the most esoteric doctrines in all Christianity\u2014the one that may at first sight seem to have the least to do with the actual physical world\u2014is the doctrine of the Trinity: that God consists of a loving communion between the Father, Son, and Holy Spirit.\u00a0 But the Gospel of St. Luke tells us that<\/p>\n When all the people were being baptized, Jesus was baptized too. And as he was praying, heaven was opened and the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: \u201cYou are my Son, whom I love; with you I am well pleased.\u201d (Luke 3:21-22<\/a>)<\/em><\/p><\/blockquote>\n There is a specific series of sense-data which communicates something about the relationship between these three entities, two of which are normally invisible.\u00a0 (The Son would also have been invisible, but for his Incarnation as a human being.)\u00a0 Combining this with other similar events, such as the Transfiguration<\/a> and Pentecost<\/a>, and the fact that Jesus claimed to be divine but also prayed to his Father, the Church came to the conclusion that the Trinity was the best explanation of the observed facts.\u00a0 If it had been based on philosophical speculation, they would have come up with some more logical way to divine divinity into three aspects (like say, Creator-Preserver-Destroyer).<\/p>\n Note that here I am addressing the question of whether the claimed <\/em> empirical facts support the theological claim.\u00a0 Although some might argue that the claimed facts support some other claim (e.g. space aliens), most skeptics would probably think that’s pretty silly.\u00a0 It’s a completely different question whether the purported testimony is actually true<\/em>, whether it really happened or else was made up by somebody.\u00a0 The accuracy of the accounts is a very important question, but before I go into it, I wanted to make sure to get clear what kind of factual support Christianity claims to have.<\/p>\n Here’s a parable to illustrate why this distinction is important.\u00a0 Water normally boils at 100 $$^\\circ$$C.\u00a0 Suppose I claim that if I drop an orange into water, it boils at 150 $$^\\circ$$C instead.\u00a0 I’m pretty sure that’s false, but suppose you claim it is true.\u00a0 And you say that you know it’s true because you went into the laboratory and tested it carefully.\u00a0 Now that doesn’t mean I have to believe your claim.\u00a0 I could accuse you of lying, or making stupid mistakes in the lab.\u00a0 But if I make fun of you for “believing without any evidence at all” and make derogatory comments about the tooth fairy and Santa Claus, then I haven’t understood the nature of your claim.<\/p>\n Admittedly, the degree to which Christian doctrine is founded on sense-data depends on the specific doctrine.\u00a0 For example, the Second Coming will involve a lot of sense-data when it happens, but because it concerns the future <\/em>the sense-data hasn’t been observed yet.\u00a0 It is based primarily on his promise that he will do so.\u00a0 It is related to his Ascension into Heaven, which is itself partially based on sense-data (so far as his leaving Earth is concerned).\u00a0 The fact that he has the power to rise from the dead and ascend into Heaven is certainly relevant <\/em>to assessing how likely he is to keep this promise to return to Earth.<\/p>\n The appeal to sense-data becomes particularly clear in the case of the Resurrection.\u00a0 Here are all the accounts of Resurrection Accounts<\/a> contained in the four Gospels, Acts, and 1 Corinthians.\u00a0 (The appendix of the Mark account is a latter addition, which was almost certainly not written by St. Mark.\u00a0 It might well go back to the first century, but for obvious reasons I won’t be putting any weight on it.\u00a0 I’ve included it solely for the sake of completeness.)<\/p>\n Note how the accounts refer specifically to the fact that Jesus had a tangible body which could be viewed by multiple people with multiple senses simultaneously, and that he eats fish in order to reassure the disciples that he is not a ghost.\u00a0 This despite the fact that he was also capable of instantaneously appearing and disappearing.\u00a0 Note also the role that doubt and skepticism plays in several of these stories, as well as the fact that Jesus could eventually be recognized, but was frequently not recognized at first.<\/p>\n This is most obvious, of course, in the “Doubting Thomas” incident I quoted yesterday<\/a>.\u00a0 St. Thomas had an opportunity to believe in the Resurrection on the testimony of others first, but he rebuffs this by saying that he needs to experience the sense-data himself <\/em>in order to believe it.\u00a0 He demands that the experiment be repeated.\u00a0 Jesus appears again a week later, and offers the evidence, but at the same time rebukes him gently by pronouncing a blessing on those who believe without seeing.<\/p>\n At this point the story is likely to raise all sorts of questions to a skeptical mind.\u00a0 Why should faith play a role at all?\u00a0 Why not just empiricism?<\/p>\n There’s some deep issues here, but let’s start with this: Jesus isn’t requiring belief without empirical sense-data.\u00a0 He’s asking for belief based on the empirical sense data of other people besides yourself.\u00a0 <\/em>That may involve faith in the sense of trusting others, but not in the sense of “belief without evidence”.<\/p>\n Leaving aside for the moment questions of why God would choose to arrange things that way, the situation itself is not that unusual.\u00a0 It is how things always <\/em>work when you’re studying History prior to the 20th century, which is not repeatable.\u00a0 It’s how things usually<\/em> work in Science itself, since only a very few people have replicated the fundamental experiments in physics personally.\u00a0 Most of us believe in scientific experiments on the testimony of other people.\u00a0 As a theorist I certainly haven’t done all those experiments myself; in fact, I haven’t even interviewed most of the people who did them!<\/p>\n This year, the Higgs boson was discovered at the LHC.\u00a0 This is Science, so the results have to be “repeatable”.\u00a0 That means, if you have billions of dollars, your own team of hundreds of scientists, and a decade of your life to devote to it, you too can discover the Higgs boson.\u00a0 But are you going to wait for that to happen before you believe it?\u00a0 No, you believe it now, on faith!\u00a0 And what I mean by faith here is not a vaporous sentimentality, but trust <\/em>based on good evidence\u00a0<\/em>tha<\/em>t the community of particle physicists is reliable <\/em>in this particular respect.<\/p>\n (I apologize to anyone who was expecting a Bayesian analysis<\/a> in this post.\u00a0 As you can see, I’m still working up to it.)<\/p>\n","protected":false},"excerpt":{"rendered":" My first pillar of Science is that it is based on repeatable observations.\u00a0 In order to see how Christianity measures up, we need to
