Dear all,

Here are two attachments as pdf files.

The first is a paper entitled, “The Continuum Hypothesis is neither a definite mathematical problem nor a definite logical problem”; it is a revision of my 2011 Harvard EFI project lecture.

The second consists of the slides for a recent lecture here, “An outline of Rathjen’s proof that CH is indefinite, given my criteria for definiteness.”

Comments welcome on both.
