Christianity — the religion of human (IV)

Filed under: The World in Fei's Eyes — Fei @ 4:19 pm

First, I’d say God want to create an intricate, self-sustained world. God will not create a broken world that require His every attention. This, is the assumption I make. (If you think the world is broken, you don’t need to read any further.) In a self-sustained world, the method to “evolve” from the most primitive living cell to the most complex human exists. However, the method exists does not mean God did not create all the living beings. The key is time. 

We say the existence of high intelligent beings on earth is a low probability event. We don’t know how low the probability is because we don’t know how large the whole set is. However, by searching neighboring planets and stars, it seems the probability is low. The evolution from one family to another family who fits the environment better is also a small probability event. The probability may be so small that each step in the evolution takes millions or billions of years following the conventional evolution mechanism. God, on the other hand, may have His own schedule. He may not be willing to wait for billions of years to see the evolution outcome. Thus, God periodically injects some minute perturbation to the world, which make small probability events become large probability events, following His discretion. If you believe the evolution process takes too long (some consider several evolution steps take too long), you can use the same argument to explain the long evolution process. 

Thus, the evolution theory and creation theory can be united. From science side, different families of animals are indeed evolved because each family of animals is only slightly different from the family it is evolved from. On the other hand, without God’s injection, we may not see such a fast (or slow) evolution, or we may not see an evolution following the current direction. In this sense, species are “created”.

Now the question becomes: how does God inject the perturbation. If the injection is too abrupt and at a large scale, it may undermine the intricacy of the world. I think the injection is in a very small scale, so small that the modern physics cannot detect the turbulence of the injection. And the nature provide a perfect means for such injections. It is at the atomic level. Remember in the previous chapter I mentioned that quantum mechanics, which is the theory to describe subatomic particle behaviors, only provide data of statistical importance? God may well change the probability of a sequence of events at subatomic level, making possible an evolution with extreme low probability (or reverse). 

Now, the controversy between creation and evolution are mitigated.

Christianity — the religion of human (III)

Here I use another example to illustrate that a middle way may be found between science and Christianity. It is the well known creation-evolution controversy[1]. I don’t want to make a judgment whether creation or evolution is wrong. I just want to emphasize that creation does not prevent evolution, and evolution also leaves room for creation. 

Evolution theory was widely accepted in the 18th century, after Charles Darwin found the connections between different species. It requires that the difference of neighboring species be small because the environmental change is slow. Thus, species “evolve” gradually. The fossils of animals need to present similar characteristics alone the time line. Most Christians believe that evolution theory has some limited success in explaining the subtle difference between neighboring species at different locations. However, they do not believe families with totally different characteristics can be evolved from one to another, such as bird and fish. More importantly, they believe that human beings were created by God as it is clearly written in Bible. Thus, they reject the evolution theory because they believe human beings are separated from other primates. [An analogy for evolution theory and creation theory is going up hill via a slope and via stairs. The height difference of two neighboring points in a slope is small, but over distance, the accumulated difference can be significant. The height difference of two neighboring points in the stairs are either negligible, or significant.]

In the early days, evolution theory was frequently attacked by the creationists that the transitional fossils (fossils transitioning from one family to another) were seldom found. However, as time goes by, more and more transitional fossils were found. It seems that evolution theory has won; creation theory has lost. 

However, creation theory directly derived from the Bible never claims that the difference among species has to be large. Only later do humans make analogy between God’s creation and human’s creation, and assume that the difference between species has to be large, because humans cannot create intricate artifacts with minute difference using his dumb hands. To me, this assumption is wrong. When God create a self-sustained world (assume the world is created), He cannot be stupid enough to leave such an obvious trace that the species are created. If species cannot evolve from one to another, the world can easily obtain a symmetric harmony. I personally believe that the Garden of Eden was such a world. In that world, time does not exist (or have no meaning). 

The Christians would disagree: you just give up creation and admit evolution, which is directly against the Bible! Don’t worry, I would say, let me show you the middle way hypothesis.

Christianity — the religion of human (II)

Filed under: The World in Fei's Eyes — Fei @ 1:46 am

At first sight, Christians have a hard time, because science is widely accepted in the world today, as scientific experiments have been tested. However, whatever God says are not tested as often.

We need to go back to the scientific method of “repetition”. This method applies better in natural sciences, and is less successful in social sciences. When we take a second look at the Bible, it is not obvious to me that God said much about natural sciences. It is understandable because the Bible was written thousands of years ago. The Bible is like a history book describing the stories or legends at that time. As we discussed before, we cannot “repeat” history. We never know what exactly happened at that time. Each party can find supporting evidence and hard-to-explain phenomena. 

Here I give you an example. On September 11, 2001, four commercial planes were hijacked and flown into landmarks, causing severe damages. It was well recorded in American history. After the attack, FBI, CIA, and homeland security operated full time to look for the terrorists. They found Bin Laden. However, mysteries of the attack were never resolved. Some people suspected that the twin towers collapsed not because of the two hijacked planes but because they were secretly demolished after the attack, perhaps for the benefit of insurance. The wreckage of UA-93, which hit west Pennsylvania, was never found. Only a big hole was found in that area. People could not find a lot of plane wreckage from the plane that hit Pentagon, and some people questioned the official announcement of the Pentagon attack. Thus, some conspiracy theories were spread among people, claiming the attacks were plotted by the US government. Which one do you believe? Each side has its own evidence. As an observer, you may believe in the US government, or the conspiracy theories. No matter what you believe, you may be biased by your own preference. You tend to choose to believe the facts that support your assumptions, and ignore the counter evidence. The 9.11 event happened less than ten years ago. If we still cannot tell exactly what happened with all the advanced recording devices we use in the 21st century, how can we be certain what happened thousands of years ago, which were only based on incomplete documents? 

You choose what you believe based on your basic assumptions. Christians would believe everything in the Bible. Atheists would only believe some history stories in the Bible, if they are supported by documents and can be reasonably explained in science. Other stories are treated as exaggerations, or imaginations.

Christianity — the religion of human (I)

Filed under: The World in Fei's Eyes — Fei @ 11:05 pm

Here I use the word “Christianity”, but it has a broader meaning than what we usually talk about in life. I will mostly focus on the existence of God (Theism) and the Old Testament. Only in the end will I mention a bit of the New Testament and Jesus. In this sense, the major part of this article can also be applied to other religions, such as Judaism[1]  and Islam, which believe in the Old Testament as well. 

I have encountered many Christians in my life. They consider the Bible as the uttermost truth in life. They place their life in the hands of God and let God make decisions for them. Whenever they encounter an obstacle, they wonder why God has chosen this way for them. Whenever they receive unexpected luck/fortune, they give credit to God. They try to find a way out between science and the Bible. If there is a potential conflict, they would doubtlessly choose the Bible and question science. 

Many atheists don’t like the life Christians have chosen. In part, Christians seem to give up part of their lives to the God. Their reasoning seems unscientific. More importantly, some Christians would argue on issues that science has already drawn reasonable conclusions. 

Christians, on the other hand, are worried for the atheists because atheists have cut their connections from God. Christians often argue that a true atheist should analyze all religions in the world and conclude that all Gods are fake and thus God does not exist (here they actually mean nontheism). However, most atheists do not even make an attempt to understand different religions and draw their conclusions based on ignorance.

I totally understand the opinions of the two parties. They make different assumptions on the world. Of course their conclusions are different. Atheists believe in science. Christians believe in God. Their conflict intensifies when science draws one conclusion and God says otherwise. But can we find a middle way that science and God can be together peacefully?


[1] At the time of writing, I didn’t know much about Judaism. Now (07/08/2011) I realize that some of my assumptions were not correct. For example, Judaism doesn’t have the notion of Heaven or Hell. It only advocates that when the Savior come, all dead will come back to life. However, it doesn’t mention what happened to those people after they die and before the Savior come. It also does not mention what happened after those people come back to life (live happily ever after?). This, in some sense confirmed my belief. See “Where are we” for details.

Atheism — the religion of science (III)

As I mentioned above, the scientific method has its limitations. It does not (and can not) reveal the secrets of the entire universe. It is only a subset (or a small subset) of all secrets that all human agree on. Science evolves over time, the theory seemly perfect now may be overthrown by a better, more seamless theory in the future. The question is, are we willing to believe in something that seems weird right now because the current science does not support it?

For example, in the middle ages, all scientific theories drew the conclusion that the earth was the center of the universe. Sun, moon, mars, and stars all circled around the earth. It was the science back then. Do you think a person at that time unscientific and believed wrong because he believed otherwise: the earth was not the center of universe? If we look back from now, we may probably say no. Because we well know that earth is not the center2. The science at that time was wrong and that person assumed correct. If, one day, God will fit in the scientific models, will the people at that time consider all the people now believing in God unscientific and believed wrong? It is a tough question… at least for people now…

I don’t know whether God will fit in the scientific models eventually. But even if it will not, can people still claim them believe wrong? After all, science only reveal a small portion of the secretes. God may well influence the world. But maybe the interaction time is too short; maybe the target is human, the observer; maybe the interaction pattern is too irregular, scientific method cannot derive useful results. It is in a gray area, and thus need belief.

To me, the scientific world is all inside a nutshell. The shell itself is composed of numerous assumptions. Science does not say anything outside the shell. But because of the Occam’s razor, the easiest assumption is that it is outside the range of science and has no effect on our world (inside the nutshell). But is it true? Nobody knows.

It still goes back to belief. After all, atheism is a religion. It is a religion of science — the current science.

2Based on current cosmology, an interpretation is that earth is not  the center of the universe. However, it is still the center of our universe: the universe that influence us (and the universe we care about). It does not mean science goes back to mid ages, but to mean yet another improvement in science.

Atheism — the religion of science (II)

Nevertheless, the scientific method works fairly well in natural science. It is, however, less effective in social science and the humanity due to two reasons.

First, the research target is human itself. Each individual is unique. Experiments on one person cannot be exactly reproduced on another person, which violates the “repeat” scientific method. Furthermore, the same experiment may not generate the same result if it is applied to the same person at different times. Human may not be objectively isolated. The person may simply interact with the rest of the world (or have time to think about the experiment) and draw a different conclusion in the second experiment. Thus, many disciplines in social science and humanities turn into researching the characteristics of a group of people, or the common parts of people. Statistics are widely used in deriving useful conclusions. It is precisely because the characteristics of a group of people change much slower than each individual person in the group. Experiments can be meaningfully “repeated” in a short period of time.

Second, some disciplines, such as history, focus on past events. We have only one chance to do the experiment, that is the time the event happens. It so happens that some information may be lost as time passes by. Later generations may only base on the remaining information and guess the cause or reason. We can only do such experiments “repeatedly” if we invent time machines, go back in time repeatedly, and objectively evaluate the event without interfering it. It is however not likely under the currently scientific discoveries (mainly general relativity). Because we cannot repeat the event, statistically, the error of such judgment is one. Moreover, people may well have predetermined judgment before analyzing the event, and thus be biased.

The distinction between natural science and social science is somewhat blurred in quantum mechanics. In quantum mechanics, the observer cannot be isolated out of the equation even for physical quantities. The quantities change so fast1 that quantum mechanics has to rely on statistics and focus its average over time. Both due to the scientific method “repeat”.

I sketched the limitations of “repeat” in scientific method above. Below I will focus on another basic scientific methodology, which people more or less focus less. It is Occam’s razor. It is often stated as “All other things being equal, the simplest solution is the best.” This principle is often used to reason the non-existence of God[3]. If the assumption of the existence of God does not help explain the phenomenon, the assumption is cut out.  The majority of the scientific community prefers to rely on explanations that deal with the same phenomena within the confines of existing scientific models[3]. This is the basis of Atheism: the scientific method cannot support the existence of God. Due to Occam’s razor, the God does not exist. Please note, however, if one day God can be fit in the scientific models, because of the same Occam’s razor, God may be assumed existence. But can God fit in the scientific models, even in the far far future?

1This is not an entirely accurate representation, but a more vivid description.

Atheism — the religion of science (I)

Filed under: The World in Fei's Eyes — Fei @ 11:42 pm

Atheism, the non-existence of God (Gods), has a wide variety of meanings. Here I use the word “Atheism” to refer to “strong atheism”, or “methodological naturalism”. It asserts the non-existence of supernatural beings and supports scientific methodology as the only effective way to investigate reality[1].

I’m not in a position to judge whether it is right or wrong. I just hope to raise some of its fundamental assumptions, benefits, and limitations.

Naturalism relies entirely on scientific method to investigate reality, which includes the making of a hypothesis, the prediction of a possible outcome, the test of such a prediction, and repetition of the experiment[2]. To me, the most interesting method is “repetition”. This makes science a universal language. Everyone believes in science. If you don’t believe in a theory, go ahead and do the experiment yourself. You can either disprove it or support it from the experiment. Here I use “support” because scientific theories can never be “proved” correct. Maybe someday a better theory will replace the current one.

However, “repetition” has several limitations. First, it requires the experiment to be repeatable. That is, whatever the “value” the experiment intends to test, it must either remain unchanged, or follow a predictable pattern over time and space. Some of the physical values fall into this category and can be tested repeatedly, but some may not.

A simple illustration of this limitation is as follows: A grown-up person Tom asks a child Jerry to investigate a table in an empty room, and asks Jerry to write down the position of the table in the room after his investigation. Note, when Jerry performs the investigation, he is alone in the room with the table. He cannot communicate with anyone (including Tom) his discovery. Only after he leaves the room can he disclose the position of the table. However, as soon as he leaves the room, Tom (or some other people) goes into the room from a back door and changes the position of the table (assume they can do it quickly enough). Because the test should be “repeatable”, Jerry does multiple tests and find the table at a different position each time. Even though each time Jerry correctly writes down the position of the table, the best conclusion Jerry can get is that the table appears randomly in the room.

Fortunately, most of the physical values at the macro level are fairly stable. They either remain constant or evolve slowly enough that people can derive the difference of the tests using known knowledge. (However, we cannot guarantee it will remain this way.) When we go into the micro world, things are totally different. Quantum mechanics is based on the experimental discovery of the “uncertainty principle”. The theory gives up identifying the exact position and momentum of a particle, but focuses on their statistical relations “over time”. Can we test the position and momentum at every single time? Maybe we can, but we get different result in every experiment (think about error!). We are just like the child Jerry in the example above, unaware there is a Tom there changing the position and momentum each time. No wonder Einstein questioned: “Does God throw dice?”

The World in Fei’s Eyes

Filed under: The World in Fei's Eyes — Fei @ 6:09 pm

This is the craziest series I’ve ever created. Since my childhood, I’ve been wondering the origin of the universe, the meaning of human beings. Now, I have some interesting thoughts and I want to write them down. I’m sure lots of philosophers must have had the same ideas, so my thoughts are perhaps not really novel… Nevertheless, I want to write them down in my own words so that I will not forget in the future…

I will start the series with my thoughts on Atheism, Christianity, and Buddhism. Then I will explain my unproven philosophy of the origin. This series is not about science. There is no true or false; there is no right or wrong. There is only belief. But, what is belief? For this, I’d like to borrow from an anonymous saying:

Belief is nothing more than a feeling of absolute certainty.
—- anonymous


Atheism — the religion of science
Christianity — the religion of human
Buddhism — the religion of everything
The story of frogs in a well
We believe in, what?
In Goddy we trust
Where are we?
Belief is everything

这两天又翻开我三四年前写的文章,觉得写得还蛮有意思的。当时是决心写完的,可写到“In Goddy We Trust”时发觉我的英语实在太烂,想表达的意思抓破头也写不出来,就停了下来。一停就停到现在,也不知能不能继续。那故事还蛮有意思的,可惜呀可惜。

× css 和 javascript 没有优化。这是很简单的优化,不过连美团这样的网站都没有做。
× 没有使用sprite功能。其实是可以做的,但没发现有什么网站做。
× 网站加速功能只支持memcache。
× 软件扩展不易。这一点我不是很确信,不过我没有在后台看见可以加模块的地方。
× 源代码没有注释。这样想要修改基本是不可能的事。只好从最土那儿定制了。
× 功能单一。只是一个团购网站,基本不可能改变用途。
× 手动要求未知。没有运行过,不知网站对人工参与的要求如何。没有发现可以运行cron的地方。


我在最初做 哈团购网HotGroupBuy 的时候,没有发现最土软件。基本上从流程到页面设计都是从头做起,花了很多时间(现在也不是很完善)。现在想来,当时的决定还是对的。
