I wanted to take a moment to offer a public apology to Professor Charles Quarles. Earlier this week I posted about a place in his recent book in which it appeared that he had inadvertently made anti-Semitic comments. A good amount of discussion took place both in support of and opposed to my original reading of the text. Professor Quarles has taken the time to explain himself here on this blog, in the comments section of the original post. Therefore, in response I have taken down the original post and I offer him my unconditional apology for any harm this may have caused him personally or professionally.
