forum for week of Nov 7: kinds of apriori beliefs

Mathematics in itself is a language, the only universal one to exist. The numbers have meanings, in whatever language they are translated to when we discuss them. I would say all our beliefs are based on the meaning we give to them, they are all relative to the way we perceive the world. But they are also all interlinked and they depend on other beliefs. Even mathematical beliefs like 2+2=4 is based on certain beliefs we have about what numbers mean and what "+" and "=" mean. Without having those beliefs, we cannot understand 2+2=4.
