IF YOU WANTED to deliberately design a collection of ideas with the purpose of making one that might eventually out-compete every other religion or political system on earth, you would be hard-pressed to do better than Islam.
Let's look at some of the individual ideas within the collection, keeping in mind that many of the ideas enhance each other. In other words, adding one idea to the others can make the whole collection more effective because some ideas work synergistically.
Here are some of the key components of the package of ideas (or bundle of beliefs) known as Islam (you can see this same list as a linked outline here):
1. A standardized version of the idea-collection is written down. This is something basic to several religions and isn't an Islamic invention, but it is an important factor in the success of Islam.
Something only transmitted orally can change over time, but something written will be identical a thousand years from now, and with modern printing presses, can be reproduced in the millions, giving it an enormous advantage in spreading identical copies of the idea-collection.
2. The Quran includes instructions for its own spread. It tells believers they must spread Islam. It is their holy duty to bring Mohammad's warnings and Islamic law to every corner of the world. Read more about that.
3. The idea-collection includes instructions for its own preservation, protection, and duplication. The Quran, the most important of the Islamic holy books, directly tells its followers that they can never change or modify or "modernize" any of the teachings within the idea-collection. It is perfect as it is. It is a capital sin to try to change it. This idea ensures the preservation of the whole collection.
These first three ideas are pretty standard for several successful religions. But now it gets interesting...
4. Islam commands its followers to create a government that supports it. This may be one of the most ingenious ideas in the whole collection. Islam is the only religion that uses it. Other groups of religious people have had political aspirations, but no other major religious group orders its followers — as a religious duty — to create a government that follows its own system of law...
