Abstract/Prior: objects: are sometimes abstract, but what we think about them is always abstract
Abstracts/abstract / Prior: "3 is greater than 4" even if not true - not eliminable - adverbs and connections can be eliminated if we introduce nominators - E.g. "that" in "that P comes implies that Q stays away" - E.g. "that P is wrong"- e.g. instead of "everything moves": "Movement is universal "- problem: there are still links (abstractions) needed - these links must be meaningful because they can be true or false.
