symbols are used to bypass our conscious awareness, while still conveying a message. it is not necessarily for the simple minded, but maybe for the uncomplicated part of our minds, going around our ego defenses.

all language is symbolic communication from squiggles on a computer screen, mammalian mouth noises coming from the front of our face, semaphore, morse code these are all symbols. we can learn to interpret them consciously or leave them in the realm of mystery. our minds are meaning generators, so why not use them.
