"Opti and I"
Have you read that thread?
It's funny to think that there weren't always so many letters in the alphabet. We had to have started with only a few, and then added gradually over time. It amazes me that we have come so far in our standardization of language (though, when you think about it, language is far from unitary). The fact that things like quotation marks have not always been a part of language is, in my opinion, evidence that there was a time before which people used written language but were not able to directly write about written language itself. Perhaps we will add punctuation in the future that allows us to more directly write about things like punctuation.
I am fascinated by the evolution of language. Adults (having advanced understanding of language) become accustomed to using many idiomatic phrases which are sometimes grammatically incorrect. And yet children learn the meaning of words in the context of these idiomatic phrases. Thus the meaning of words changes gradually over time. We don't usually think about what we unintentionally imply individual words to mean in hip phrases, but the hip ways in which words are used today will become the standard of meaning for those words in the future.
Likewise, ideas evolve over time as do the words used to define/describe them.
Every day I am thankful that I was introduced to psychedelic drugs.
