Someone called this columnist's bluff and asked for a straightforward account of an obscure argument in a previous column.

What do you make of the result?

• Was it well done?
• Do you now understand it?
• If you understood it before, was anything lost in translation?
• How much does the {lost in translation} stuff matter?
• Accepting that some academic and technical jargon and discourse is necessary, how do we define the boundaries?
