Would you please tell me the overall meaning of the following sentence?
"Almost since the invention of writing, more than five thousand years ago, the signs that stood for words that expressed (or attempted to express) our thinking appeared to its users as models or images for things as intricate and aimless, as concrete or as abstract as the world in which we live and even life itself."
especially the marked part is confusing me. Does it say that "things" in the world is as intricate, aimless, concrete and abstract as the world itself?
Thanks for helping.
