Query: tiresome and ignorant

The problem is simply that Posner knows very little about literature and literary history. Thus he is given to fatuous efforts such as his speculations on why Shakespeare did not publish his collected plays when the fact is that in the early 17th century, playwrights made very little from publishing their writings, and hardly anyone bothered to publish their collected works. (When Ben Jonson did in 1616, he was widely ridiculed.) Posner's book is riddled with egregious misstatements of this sort, which would be comcial to anyone with the most basic education in literary history. In attempting to draw legal conclusions based on faulty information of this sort, he only creates further confusion.
