The article is pretty light on content, and the premise is kind of silly. Numbers are tools and are no more or less meaningful in some transcendent sense than the Craftsman socket wrench set I left in Michigan. I could be biased, though. I find the metanarrative, "truly real", objective meaning, transcendence thing to be incomprehensible.

It's interesting primarily for Klintus Fang's comment in response to Wilhelmus.
