If physical fitness is seen by your society as the highest form of self-improvement, them yes. I believe the Greeks considered an enlightened mind to be evident in a beautiful body, so among them, the practice of sports could be considered religious. This is evident in their use of various tournaments to honor the gods and their portrayal of the gods and physically fit.
This is circumstantial and self-fulfilling. Essentially what you are saying is if you bridge enough references together you can connect two divergent concepts. First off, you have to draw the line somewhere. If we follow that reasoning far enough we could say that Starbucks is my temple, my barista is my priest, and a grande white mocha is my Eucharist because I consider coffee drinkers the epitome of enlightenment. Second, athletics is something that developed in multiple places around the world completely independent of any specific religion. Just because someone dedicates an athletic competition to a certain god does not mean that the two an intrinsically linked, rather that the people are merely paying the appropriate homage to the patron god of the event and asking his blessing to successfully conduct it. Gods were portrayed as physically fit for what I think ought to be obvious reasons. Gods were supposed to be unbelievably strong beings, with powers beyond comprehension and as such, you can't exactly sculpt marble statue of your average joe nobody.
The Buddha, on the other hand represents a different ideal and therefore takes on a wholly different form.
Buddha does represent a completely different ideal. For one, he is based on a real human being as opposed to a completely mythical deity. As for the "form", not all representations of the Buddha are porcelain statues of a fat dude on a mat.
Also, I believe the May once had a cult called the "Cult of the Fat Man" which worshiped idols resembling the Buddha but that's besides the point.
And there was a cult once in California that thought the world was coming to an end at the passing of a comet so they all killed themselves. Hey, it happened and is in the history books, maybe someone will cite that in a religious debate 200 years from now.
Also, there is no limit to how many societies can have the same values. Even different religions with different practices and beliefs may aspire towards the same goal. Technically, the ideal of enlightenment is the same in all societies, but is expressed differently by all. The most radical difference being in how one judges who is enlightened and who is not. But one could very well say that some people get the same feeling from playing a violin as another might torturing children to death. Due to the radically different contexts, expressing the feeling which both activities evoke in different people is practically impossible to do in words, but expressing it through allegory is very possible
Of course many people can share similar values.
Many diverse religions do aspire to similar goals.
The idea of enlightenment is most certainly
NOT the same in all societies. This could be an entire post on it's own.
The fact that religions have different criteria for what is sacred or divine is hardly radical. In fact, it is the most basic and ordinary thing by which you classify beliefs.
Yes, many emotions, in fact I would argue
all emotions are impossible to really qualify with words. I mean how do you really describe even a basic feeling like happy? You could say "Oh, it's when you feel good", but then the question becomes what does feeling "good" feel like? See where this is going?
"If religion is by definition worship of supernatural entities, the answer must be that Confucianism is not a religion. If, on the other hand, a religion is defined as a belief system that includes moral stances, guides for daily life, systematic views of humanity and its place in the universe, etc., then Confucianism most definitely qualifies. As with many such important concepts, the definition of religion is quite contentious." from the wikipedia article on Confucianism.
A. For the record, though Wikipedia is a very useful and handy resource for finding quick and general information about a particular topic, it is not the indisputable guardian of knowledge. Any one of my profs would have failed me if I ever had the nerve to cite Wikipedia on a paper, or ANY encyclopedia for that matter.
B. If you notice the banner above that particular section, even Wikipedia cannot agree on the validity of that passage, thereby making it an even poorer choice of citation.
C. That said, I'm inclined to agree with the many scholars who do not in fact consider Confucianism a religion. Personally, I do not think it meets the criteria and I think Firaxis was wrong to include it. I think they were looking for one more religion for the game and wanted something that would be recognizable and that had a significant impact on history. Just as Wikipedia can make mistakes, so too can Firaxis game developers. Imo, Confucianism is simply an ethical code of behavior.
Basically, Communism could be a religion in Civ 4 if it became convenient for it to do so. It even has sects such as Leninism, Marxism, and Maoism. Stalin could be a great prophet. It even spreads like a religion, disseminating amongst the people by way of philosopher soldiers before taking over the government.
Democracy has "sects" too. Republican, Representative, Liberal, Direct, etc.. It too tends to spread amongst the people by means of "philosophers". Does that make Democracy a religion too? Is Thomas Jefferson a great prophet?
