Are all religions basically the same?

11 Comments

UPDATE: Welcome visitors from The Western Experience! Thanks for the link, Jason!

I’m sure that all my readers will have noticed that there a huge number of different religions in the world. This is called religious pluralism. Religions all make claims about the way the universe is, and the way that we ought to act in order to solve the problems that we all face as human beings.

The law of non-contradiction

To start with, we all need to be familiar with the law of non-contradiction. This is the stuff that software engineers all learned in undergraduate computer science courses. Computer science is a lot like analytical philosophy because both study symbolic logic. Analytical philosophy is as rigorous as mathematics.

The law says that for any proposition P, P cannot be true and not true at the same time, and in the same context. For example, let P be the statement “it is raining outside my window right now”. It is impossible that the reality of the world be that it is raining outside my window right now, and not raining outside my window right now.

The external world is shared by all of us, and it is objective (it is not affected by what we think about it). When we make propositional claims, it is the external, mind-independent world that makes claims true or false. And by “world” I mean all of reality, past, present and future.

Similarities between religions

On a superficial level, religions are similar because they all try to answer the same kinds of questions:

  • what is the nature of the ultimate reality in the universe?
  • what is the fundamental problem faced by human beings?
  • what should human beings do to solve this problem?

These questions are shared by all religions, but on a more fundamental level, religions are all completely different because they give mutually exclusive answers to these questions. Therefore, according to the law of non-contradiction, they cannot all be true at the same time and in the same context.

Differences between religions

In this post, blogger Neil explains how the Christian Bible claims that Jesus died on a cross, but the Koran claims he did not die on a cross. How do we understand these two contradictory claims? Are they propositional truth claims about the external world, or something else? There are two answers.

Postmodernism: Treating religious claims as subjective nonsense

We could say that all religious claims are just nonsense, and are not intended to apply to the external world, but are just personal preference claims about each believer – they are neither true nor false. The problem is that the postmodernist is then being condescending to the religious adherent by redefining their own words.

Rationality: Treating religions claims as genuine claims about reality

We could instead avoid insulting believers by being condescending about their claims. We could say that all religious claims are exactly what the believers claim they are: real claims about the external world. We could then resolve the conflicts using the same tools we use in our everyday lives: the laws of logic and empirical evidence.

How do postmodernists reinterpret religious claims as non-propositional?

Here are a few ways that postmodernists reinterpret the conflicting claims of different religions:

  1. relativism: you reinterpret truth claims of the different religions so that they are claims of personal preference, which express the deluded myths that each individual religious person finds “fetching”
  2. pragmatism: you reinterpret truth claims of the different religions so that they are claims of personal selfishness, so that each religious believer chooses the delusion that is personally satisfying to them
  3. syncretism: you re-interpret truth claims of the different religions so that claims that are absolutely central, such as “was Jesus God?” are reinterpreted as being peripheral issues, and then the religions can all agree on the core of religious belief, such as advocacy of socialism, global warming and abortion

Why would postmodernists want to treat religious claims as nonsense?

In addition to the desperate desire to keep God from having authority over our moral decision-making (i.e. – sin, rebellion, etc.), there are 3 reasons why people try to treat religious claims as non-propositional nonsense.

  1. Ignorance: people do not know the conflicting truth claims that different religions make
  2. Laziness: people do not want to have to spend time evaluating the competing truth claims
  3. Cowardice: people do not want to investigate and debate truth claims: it makes them unpopular

Postmodernists have decided that the purpose of life is to be hedonistic, and not to worry about the world really is. They think that trying to find out the truth about our origins, our purpose, and our ultimate fate is hard work, and talking about it makes them unpopular. So they don’t want to do it.

But that is not what they say when you ask them. Instead, they say that disagreements about religion has caused a lot of wars, and so it’s better if we just reduce the question of truth in religion to personal preference. That way, everyone can choose the delusion that makes them happy, (although religions are all actually false).

But postmodernists are arrogant to redefine the claims of all religions as nonsense. And it is self-refuting because they are substituting their own view of religion as objectively true, which is just what they deny everyone else. And if disagreeing about religion causes wars, then why are they disagreeing with us about religion?

So then how do we deal with the plurality of religions?

The answer is to treat religion the exact same way as any other area of knowledge. We can tolerate people’s right to disagree, disagree while still being polite, and resolving disputes using logic, and evidence supplied from disciplines such as analytical philosophy, scientific investigation, and historical analysis.

People who want to involve emotion and intuition in the process of testing the conflicting religious claims can just butt out of the conversation. The search for truth should proceed irrespective of what you think about the truth claims of religion. Yes, the doctrine of Hell offends people, but that doesn’t make it false.

Further study

Portions of this article were borrowed from this lecture by philosopher Douglas Groothuis, in which he explains the how to think carefully, using the laws of logic, about religious claims and the fact of religious pluralism. Note that Doug is a lot less snarky than I am in the lecture.

Also, I noticed that Unbelievable has posted a debate between Muslim Shabir Ally and Christian Tony Costa on whether Jesus dried on a cross and whether he rose from the dead.

Here are some related posts on the question of postmodernism and testing religious claims. All of them are far, far, far less snarky than my post today.

Reviews of Christopher Hitchens’ book

4 Comments

I saw this book review about Christopher Hitchens’ book “God is Not Great”, written by Melinda Penner of Stand to Reason.

The post is here. Here is an excerpt:

Let me say something that isn’t very pleasing to think about Religion isn’t false just because it’s cruel.  Even if every one of Hitchens’ accusations were accurate, they don’t disprove the truth of religion.  God might be a cruel being who does delight in manipulating man.  In that case, Hitchens’ claim that “religion poisons everything” might be true, but his real claim is that God doesn’t exist.  And that just doesn’t follow from every evil example of religion.

What standard of morality is Hitchens using to judge God and Christians as evil? If it is his personal preference, then who cares what he thinks. If it is the current fashion of the culture he is in in this time and place, who cares? That “standard” will change as time and place changes. It’s convention. But, if it is an objective moral standard that exists independently of what individuals and cultures think, then God exists to make that design for the way the world ought to be.

Next excerpt:

Hitchens says religion is evil, and he does mean evil and sin.  He freely uses moral language to pin the blame right where he believes it belongs, but he never explained how he, as a materialist, can use moral language and mean them as moral terms that all mankind are beholden to….

As I mentioned, Hitchens professes materialism, believes it’s proved.  He freely makes moral accusations against religion and religious people.  He freely admits contempt, and, given what he believes, that would be the proper response.  He accuses religion of sins and evil.  These are real, objective categories for him, not his personal sentiment.  He never explains how, as a materialist who believes in a world of only what science can explain and prove in the physical world, he can lay claim to morality.  He ignores the grounding problem, the explanatory power of a view of reality to account for the features in it.  Morality, the way Hitchens is using it, has no material explanation.  How does he account for the prescriptive, universal nature of morality, not merely descriptive?  His humanism won’t get him there because that can only offer a descriptive, contingent account – whatever is is morality.  On this major flaw alone, it’s justified to ignore anything Hitchens claims because his view of reality can’t lay claim to morality.

Melinda wants to know how Hitchens’ can help himself to the notion of rationality on a materialistic worldview. After all, if materialism is true, humans are pure matter. Everything humans do is causally determine by their genetic programming and sensory inputs. But that behavior is targeted towards survival and reproduction not reasoning about the external world.

She writes:

There’s more to the grounding problem, too.  Is rationality material?  He can’t even ground the rationality he sees as the crown of human progress.  If man is purely material, then he’s a machine programmed by nature, c-fibers firing, acting according to the laws hard-wired by his biology.  He lauds the “chainless mind,” free from religion.  Yet in his view of reality, man is chained by determinism with no escape.  There is no rationality because there is no option to behave, think, believe any way other than we do.  There’s no point in even trying to persuade religious people to believe and behave different since we’re also just acting the way we’re programmed to.  Indeed, even scientific inquiry that Hitchens offers as the hope of mankind is nonsense since only one conclusion is predetermined by our programming.

And it goes on from there. I’m looking forward to the (not yet planned) debate between Melinda Penner and Christopher Hitchens! Because I think she could kick his butt with half her brain tied behind her back.

If you want to get ready for the debate today between William Lane Craig and Christopher Hitchens, check out my analysis of the 11 arguments Hitchens made in his opening speech in his debate with Frank Turek. You can also watch or listen to a preview debate that was held in Dallas recently between Craig, Hitchens and some other people. Biola University is live-blogging the debate as well.

UPDATE: I was just chatting with Brian Auten of Apologetics 315, and he recommended this review of Hitchens’ book by Douglas Groothuis. This is a 28-minute audio clip.

Is one true religion even possible?

Dr. Walter L. Bradley

This is a follow-up to my previous post on Walter Bradley’s lecture about the scientific evidence for an Creator and Designer of the universe. Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor, and a great example of the integration of Christian faith and a stellar academic career.

Is there truth in religion?

Another one of Bradley’s lectures is on the question “Is There Objective Truth in Religion?“. In the lecture, he describes a book by Mortimer Adler, called “Truth in Religion”. In the book, Adler makes a distinction between two kinds of “truth”.

  1. Trans-cultural truth – also known as objective truth. This is Adler’s term for the correspondence theory of truth. A claim is true if and only if it is made true by corresponding to the state of affairs in the mind-independent external world. It is irrelevant who makes the claim. The claim is either true or false for everyone, e.g. – “the ice cream is on the table”. Either it is, or it isn’t, for everyone.
  2. Cultural truth – also known as subjective truth. This is Adler’s term for claims that are arbitrarily true for individual and groups of subjects. For example, your personal preference for a certain flavor of ice cream, or the cultural preference for a certain style of dress or cooking. The claim is true for the person or group, e.g. – “I/we prefer chocolate ice cream and wearing tuxedos”.

The question that Bradley addresses in the lecture is: are religious claims trans-cultural truth or cultural truth?

Why do people want to believe that religious truth claims are subjective?

People want to believe that religious truth claims are subjective because religious claims differ, and people lack the courage to tell some group of people that their beliefs about the world are wrong. By reducing religion to personal preference, no one is wrong, because everyone who believes in any religion, or no religion, is just expressing their own personal preferences.

But, if religious truth claims are trans-cultural claims, e.g. – the universe began to exist, then some religions are going to be wrong, because religions disagree about reality. It’s possible that no religion is right, or that one religion is right, but it is not possible that they are all right because there is only one reality shared by all people. Religions make contradictory claims about reality – so they can’t all be true.

Suppose religious claims are trans-cultural? How would you test those claims?

I credit E.J. Carnell with a test for truth that I still use today. It is the same test used by Adler and Bradley.

  1. Logical consistency (the claim cannot violate the law of non-contradiction)
  2. Empirical verification (the claim is verified against the external world)

Adler says that other trans-cultural truth claims, such as those from math and science, must all pass the test for logical consistency, as a minimum. And so with religion, if it is like math and science. Once a proposition passed the test of the law of non-contradiction, then you can proceed to step 2 and see if it is empirically verified.

Adler surveys all the major religions in his book, and concludes that only 3 of them – Judaism, Islam and Christianity – pass the test of the law of non-contradiction. He ends the book by recommending to seekers that they proceed to evaluate the historical claims of these 3 religions, in order to see which if any passes the empirical tests.

Conclusion

Bradley concludes with the claim of the resurrection of Jesus could be investigated using historical methods, in order to decide which of these 3 religions might be true, if any. He also mentions the stories of a few people who performed the investigation and changed their initial opinion of the resurrection in the face of the historical evidence.

I blogged previously about whether the Bible teaches that faith is opposed to reason and evidence and William Lance Craig’s refutation of postmodern sketicism of religion. I also blogged about scientific and historical evidence that could also be used to test religious claims. My post on N.T. Wright’s view of the resurrection may also prove useful.

Also, a good debate between a Christian and a postmodern relativist on truth in religion is here.
