World Peace is Easy
World peace is an unusually simple problem: it's entirely a marketing problem. We don't even have to get people to buy anything, all we have to do is get them to want it. The marketing is the whole problem. Once everyone wants it, then the problem is solved because no one will fight anymore. It really is that easy.
In talking to people, I have observed three broad 'market segments' that need to be addressed, three types of people. Maybe there are more, but this is what I have found so far:
1) Those who think that humans are violent by nature, and thus war is inevitable. These are believers in the 'killer ape' theory or perhaps they've just seen too much violence in their lives. Fortunately men are not violent by nature, the 'killer ape' theory is discredited, and in any case we are capable of choosing our destinies.
2) The second group are those who would stop fighting, but the 'other guys' won't stop. These are most Americans. They didn't want to attack Afghanistan originally, but the Afghanis struck first, so what choice was there? These people happily would support peace if they saw it as a viable possibility. Fortunately, peace is viable because it is the most profitable solution, we just need to help the world see that. The more people start supporting peace, the more this group will become convinced that peace is possible.
3) The third group is the most difficult group, because they actually have something to gain from war. In this category was Slobodan Milosevic, who wanted to consolidate power in his country, or warriors on the edge of the Sahara who want to take others' land for their own cattle. Some people fight because it is exciting, they like the thrill. These people need to see that there is a better way, and that their children will want to live in peace, and sometimes compromise is worth it. Anyone who has loved has learned the value of compromise. These people can too.
Try to talk to everyone you can about world peace, because word of mouth is the best type of marketing.
Religion is falsifiable
Religions are falsifiable (science is the un-falsifiable thing: it is a tool, not a proposition. How do you falsify a hammer? How do you falsify science?). Any decent religious system has ideas of the type, if you do X, then Y will happen. Let's investigate a bit, and see what some religions say:
Buddhism: if you follow the eight-fold path, your suffering will end. Extremely testable. If you follow the eight-fold path, and you are still suffering, then man, they led you astray.
Tantric yoga: do these exercises and meditations and eventually you will have a kundalini rising (enlightenment). So if you do them, and you don't have a kundalini rising, then you know tantra is worthless (either that or your teacher sucks).
The Bible: Those who believe shall be able to do miracles, such as drink poison and not get hurt, or heal the sick (Mark 16:17). So if you follow Christ and you can't do those things, then......yeah, you've just falsified it.
Daoism: 99% of the battle of daoism is figuring out what you are supposed to do. That is an ancient Chinese way of teaching.....but, if you ever do figure out what it is you're supposed to do, then you will be able to tap into the mysterious power of the Dao. If you figure out what you are supposed to do, and do it, and still can't tap into that power, then you've just falsified Daoism.
Mormonism: fast and pray oft, grow in humility, and you will be filled with joy and consolation. I really like Mormonism because it is even more scientific: it says all over the place things like, "if you have faith, God will give you anything that is good." It gives examples of people who became good enough that God gave them anything they asked for, and it says that you can do it too. It even directly gives an example of how to test these claims, and verify/falsify them. I like it because the more clear the promises, the more easily it is falsifiable.
See? If all you are saying is that some being out there exists who affects life on earth in some undetectable way, then yeah, it's pretty pointless. But any preacher who preaches that doesn't know his religion.
