1. imo Occam's razor is abused
IMO nothing is wrong with Occam's razor statement in Quote 1, so I agree with it.
Here is another way to say Quote 1 but in more mathy terms:
1.1. a case where Occam's razor is not abused
Before I show you how Occam's razor is abused, let me show you a case where it is not abused.
Suppose that we want to predict how far would a 100kg stone travel after being thrown by a catapult. Then, someone proposes function $$f : x_1,_2,\ldots,x_n \to [0, \infty]$$ where $x_1,x_2,\ldots,x_n$ are some input numbers that quantify things, such as stone's mass, stone's shape, length of the catapult's arm, amount of force that moves the arm, etc.
Suppose that $f$ is pretty accurate in predicting how far the stone would travel, with an error that follows the normal distribution $N(\mu, \sigma^2)$.
Nice, right? So now we can use the function $f$, feed it with input, and pretty accurately get where the projectile would land.
But now imagine some other dude found that the $n^{th}$ input of $f$ was not needed, so he came up with another function $$g : x_1,_2,\ldots,x_{n-1} \to [0, \infty]$$ that needs 1 less input (no need for $x_n$), and is also exactly as accurate with an error that follows the same normal distribution $N(\mu, \sigma^2)$.
As you see, the utility of $f$ is exactly identical to $g$'s, and hence the extra complexity of $f$ due to it needing $n$ many arguments (instead of $n-1$ as in $g$), is unnecessary complexity.
Hence, we can rightfully conclude that $g$ is a better model in explaining the phenomenon than $f$.
1.2. a case where Occam's razor is abused
What if I tell you that, while $f$ needs an extra argument that $g$ does not need:
- $f$ is much faster when implemented in a computer, which allows calculating catapult's expected accuracy much faster in field, hence increasing its fire rate.
- The extra argument that only $f$ needs, i.e. $x_n$, is a constant specific to the catapult, and is easy to obtain.
In this case, $f$'s extra arguments is suddenly not unnecessary any more because the extra argument allows to increase the utility of $f$ in a scenario that we care about. Therefore, IMO using Occam's razor here to reject $f$ is wrong.
See, utility is important. If more things increase a thing's utility, then those more things are no longer unnecessary, and hence Occam's razor does not apply to them.
Utility depends on the domain/scenario. E.g. in the scenario of Section 1.1 $f$'s more things is unnecessary, and hence Occam's razor applies to eliminate $f$. But in this section's scenario $f$'s more things is not unnecessary and hence Occam's razor does not apply.
1.3. is believe in God unnecessary?
I agree that, say, physics' models probably don't need believe in God. E.g. if you give me an equation to model gravity that somehow incorporates believe in God into it, then most likely your model has a unnecessary complexity over the existing physics model for gravity, which lacks believe in God.
But does this mean that, in all scenarios, believe in God is an unnecessary addition? Simply because adding believe in God in some models, such as physic's models for gravity, is unnecessary, it does not mean that believe in God is unnecessary in virtually every other scenario.
E.g. $f$ is not virtually unnecessary in all scenarios. $f$ was only unnecessary in Section 1.1's scenario, but it was totally necessary in Section 1.2's scenario.
Therefore, if any person claims that “believe in God is unnecessary. Period!”, then that person must prove that there is virtually no scenario at all where believe in God has any utility.
I have never seen any person manage to back the claim that “there is no scenario where God is necessary”. Therefore, by the same sciencey stuff they claim they like, I hereby call their claims unsubstantiated.
1.4. proof that believe in God is necessary
Section 1.3 showed how the claim “believe in God is unnecessary” is actually unsubstantiated. In this section, I will take it further by showing you that it is actually false.
Theorem 1. Believe in God is necessary.
1.4.1. Theorem 1's proof
First let's define some basic tools1:
Definition 1. For a thing $a$ to be necessary, there must be a senario $s$ where $a$ has maximum utility over its alternative things.
Definition 2. For any scenario $s$, and for any pair of things $a$ and $b$, $a$'s utility is more than $b$'s in scenario $s$, if and only if $a$ achieves the goal of $s$ better than $b$.
Axiom 1. Our goal in reality/nature is to maximize what is good.
Definition 3. A thing is good if it maximizes our survivability. Click here for more info about this definition.
In order to prove Theorem 1, all we need to do is to show that there exists a scenario $s$ where believe in God has a higher utility than otherwise.
Below is a list of scenarios where believe in God results in a higher survivability of its followers (one is enough, but I show more):
- Statistics show that those who commit fornication
increase their divorce risk by more than the double.
Logically, it's no brainer to see that more divorce implies more kids that are raised by single-parents. Statistics show that single-parented children are more than twice as likely to commit suicide.
As you know, Abrahamic religions forbid sin, and therefore this is a scenario where believing in the Abrahamic God results in saving some lives, aka maximizing the survivability.
You may say, but what if parents never get married? Well, stats show that they have even higher separation/dumping rate. So.. really, the best way for your children is a proper Abrahamic marriage.
- LGBTs have increased suicide risk. Obviously Abrahaic religions are against this faggy shit, and hence believing in the Abrahamic God helps saving lives (aka increasing survivability).
- Believe in hell lowers the crime rate. Obviously, another property of Abrahaic religion is hell. This is why I also personally think “hell” is a mercy, as it lowers all kinds of crime rate including homicide. For those who complain about the Abrahamic God for having hell, think again.
- Believe in God extends our optimization scope, which allows us to be more likely to invest in good very long-term projects that non-believers won' — for more info read this.
- I can pull more, but I got tired. So let's stop here.
On the other hand, I don't know any general statistics that show that believe in the Abrahamic God is harmful. You might be thinking of ISIS, or religious wars. But I have two points for you:
- ISIS exists in a proxy war situation and receives foreign funds, plus they themselves violate Abrahamic teachings as they kill innocents, even by Quranic standards.
- In the history of all wars, religious wars make up only 6.97% of them. Meaning, non-religiousness resulted in much more wars. Meaning, religiousness correlate with reduced wars.
IMO it should be very clear that believe in the Abrahamic God increases our survivability. Then:
- By Definition 3 we can see that believe in the Abrahamic God is good.
- By Axiom 1 we can see that believe in the Abrahamic God allows us to meet our goal better
- By Definition 2 we can see that there is at least a scenario $s$ where believe in the Abrahamic God has more utility than otherwise.
- By Definition 1 we can see that believe in the Abrahamic God is necessary.
