Neato construction,

Mr. Dschwartz, but I fear that lingual constructions that you feel exist will be found to be as rare as ticks on a turtle. Think a minute. What grouping of thought concepts could be arranged so as to have an inadvertant conceptual gravitation towards paradox. You'll agree not many. But think about it, your question ...

While "sophmore" will always be an oxymoron, "exoteric" will be paradoxical only as long as its use remains limited to a small circle of people
is in itself paradoxical.

In the absolute, David, that is true. But do you have time to find another?
