Recently during a class on Philosophy of Language, I made (a student in the class) a presentation on constructed languages. As I was going through some of the earliest projects in history, I mentioned Descartes's idea of creating a simpler language, lacking typical natural language complexities as irregularities. That prompted a few classmates who contended that that was impossible since every human language is equally complex. I tried to reason that Descartes was not pointing to a capability of a language expressing intricate ideas, but simply to the way some languages work which do appear to be rather straightforward. Grammarwise, for instance, English seems to be simpler than many other languages. Some could defend that the English spelling is more complicated than many other tongues as well, but the fact remains that, for the most part, English does seem simpler than Estonian or Hungarian, for example. What are your thoughts?
