Pasigraphy
Pasigraphy is a
writing system where ideas or concepts are put down rather than a representation of the sound of a language. The emphasis is on having a systematic, philosophical system.
Pasi in
Greek means "to all". Historically there have been several attempts to come up with this.
Leibniz had been considering this idea and
Alexander von Humboldt as well.
