Upon returning to England from France, the good doctor takes advantage of the mandatory quarantine to make progress through his massive library by reading a book on the once-famous British judge, Lord Darling.

Well, even Homer slept, and in any case there is no suggestion that Darling let his very strong private prejudices interfere with his administration of the law, in which he scrupulously tried to be fair, if (like all human beings) he was not always right. And this is a very important point that goes to the heart of the jury system (in which I believe), and indeed of human life itself, namely that people are able to abstract themselves from their prejudices in certain circumstances and deliver themselves of an opinion—for example, of guilt or innocence—according to the evidence presented. Indeed, if this were not the case, what would be the point of ratiocination at all?
