When you think about it, he was right: most all of our words and phrases are but analog comparisons to some other notion or thing. And, what Nietzsche may not have realized (probably did) but contemporary linguists, computer scientists, AI esxperts and neurobiologists all certainly understand, is that language has an even more fundamental role in human intellect than mere communication (itself damned important!). Indeed, the way we process and store information is through subliminal use of vocabulary, syntax and grammer: the reason we can’t consciously recall things that happen in the first few years of our life is that we don’t yet have the verbs, nominatives, qualifiers, etc., to rationalize, remember an rearticulate them even in our own minds!

`just another slant on “language.”
