There are some important implications to this. Socrates is a man. Therefore Socrates is mortal. Now if you aren't forced to use nouns in order to make complete sentences, then there must be kinds of logic that don't need nouns.

Logic grows out of the grammar of each language, so there is just simply NO universal human logic.
Second, let's think about health and our bodies. Our society and its institutions, perhaps especially the medical institution, are driven by nouns.
