Whenever I tell someone that my book in set during WWII and contrasts microbial intelligence versus civilized stupidity, this often quickly leads to an argument over whether anyone but humans can show true intelligence.
(I suppose this is progress, of a sort - we are long past people claiming that only middle class protestant white males are capable of exhibiting true intelligence.)
But as a consequence, I am recasting my book's main theme as the contrast between 'microbial complexity' and 'civilized simplicity'.
