In the preface to the book _Descriptive set theory and forcing; How to
prove theorems about Borel sets the hard way_ Arnold Miller writes:

Any mistakes here are the responsibility of the reader. If anyone
wants to point out a mistake to me, I promise to respond by saying
"but you know what I meant to say, don't you?"

An eminently sensible disclaimer.
