Sentences of Enduring Value

Just in case you missed it, let me repeat: when it comes to the kind of intra-nation inequality that we should really care about (if we are going to worry about intra-nation inequality at all), we “do not know.” As in “know” and “not” put together. “Not” is the word of negation, by the way. And the last I looked, not = not, as it usually does on most Wednesdays. Would you like to hear more on what is implied by the conjunction of “not” and “know”?
