A symbol is not only universal, but also extremely changeable. We can express the same meaning in different languages, and we can also express some ideas and concepts with different words in the same language. The real human symbol is not embodied in its unity, but in its versatility. It is not rigid, but flexible.

Cassirer believes that it is these three characteristics of symbols that make symbols surpass signals. Cahill took Pavlov's experiment on the second signal system of dogs as an example to illustrate. He believes that the "clock" as a "signal" is a physical fact and a part of the physical world. On the contrary, human "symbol" is not "fact", but "ideal", which is a part of the world of human meaning.

Signals are "operators" and symbols are "objects". Signals have some physical or substantial existence, while symbols are conceptual, meaningful and functional.

With this special function, human beings can not only passively accept the influence of the world and make factual responses, but also make factual responses to the influence of the world and actively create and explain the world. It is with this symbolic function that people sublimate from the pure animal natural world to the human cultural world.
