Yes, it is a commonly known name. Unfortunately, that is partly because it was used as a type of joke when I was young! But - we do have a Confucius Institute at the University here in my city, and that was where I started my interest in learning Chinese. I don't think many people here actually know much about Confucianism though, unless they have studied Chinese or philosophy. I think that Chinese culture is starting to have more of an effect in the west, due to the numbers of Chinese immigrants. Chinese people have a tendency not to interact much with people in the countries they move to, but some do.
