My comments were not to imply Berkley was not important. I do not quite understand this:
“Berkley was the first philosopher to make the claim that language can be used for a variety of things besides describing things.”
I cannot believe you mean by this what it seems to mean. When was it ever not known that language is used for many things besides “describing thing.” Anyone familiar with Aristotle’s epistemology would know that a large part of it is describing the different uses of language, of which “describing things” was just one of many.
Perhaps I’ve misunderstood what you intended.
