It has been argued that perhaps the symbols we use are what create concepts, and therefore no common understanding between cultures, races, or times is possible.
Dramatica works because indeed there ARE common concepts: morality, for example. Morality, a common concept? Yes. Though not everyone shares the same definition of morality, every culture and individual understands some concept that means “morality” to them. In other words, the concept of “morality” may have many different meanings — depending on culture or experience — but they all qualify as different meanings of “morality.”
Thus there can be universally shared essential concepts even though they drift apart through various interpretations. It is through this framework of essential concepts that communication is possible.
