No. We just needs symbols that are specific enough to have a unique reference. The symbol does not need to be unique.To be more specific, the words "orange" and "particles" are not the actual orange. There is only one unique orange. So if we are truly going to let a symbol stand for that unique orange, then we must have a unique symbol.
Object A means object B, where object A is the word "wheel" and object B is the wheel. However, object A is not object B. Do you agree with the latter statement?
Yes. A word is not a wheel... Obviously.
