It is amazing how little thought people today give to symbolism. Throughout the ages, people were well aware of the symbols used. Every tradition has them going back thousands of years. Yet today, we pay no attention.
Of course, that does not mean that we do not use them. Madison Avenue has clients spending billions to make sure we recognize and interpret the symbols the way they want us to. We call it branding but it is rally symbolism.
We think in pictures. That is something that most forget. Hence, when something is ingrained in us, especially without questioning, it carries meaning. Is it any wonder Ronald McDonald is one of the most recognized figures in the world. The symbolism of what that character means to children is well honed.
