There are pretty many philosophers who talked and wrote on the philosophy of language. Usually language only means the use of words and symbols, however, I noticed that symbols may have different forms, like flags, logos, hymns, etc. There is also such a thing as body language.
This made me think that language is much wider than simply words and letters. But I thought about how do people get the "meaning" of symbols. The meaning of a sound pattern (utterances, in particular), the meaning of a flag, the meaning of a handshake, etc. So, I turned back to my associations theory.
If you hear a roar, then it very likely means there is a dangerous animal nearby. If you hear someone utters a particular sound pattern that you call your name, that very likely means the person wants you to hear them (and do something, maybe). I don't think this is a new view and I'm not the first with that theory. People say this is quite a classical thought.
But then we can say that language is not different from cognition as a whole. It is a subtype of cognition, more precisely and not merely something tied to cognition (post-modernist thought, right?). This would have huge implications on cognitive psychology and linguistics. This makes it possible to talk about cognitive games, generalizations of Wittgenstein's language-games. We also can assume that for a human it's similarly hard to change/acquire alternative ethical/cognitive habits as it's to acquire second language.
Also, it results in a difficulty of distinction between symbols and non-symbols. That is, almost anyone will say that 'A' is a symbol. Many will say that flags are symbols, because many people deem them valuable. Yet, there are dreadful symbols, like a black cat or an eclipse (and both prove that symbols are not necessary something human-made). So, it appears that people might call something a symbol because other people have irrational beliefs about them. But even the one who actually values "his" flag, also will tell that a flag is a symbol.
Yet, how can we say that a real roaring lion in front of us is not a symbol? Symbolic black cats are as real as that lion.
But are there philosophers who have similar views? Are they united under some camp? And are there some sources where I can read about that them?
