The editorial board of Philosophia Mathematica have discussed the review of Haverkamp’s book (see the post below). The general editor, Robert Thomas, issued the following statement:
In the recent review of Nick Haverkamp’s Intuitionism vs. Classicism: A Mathematical Attack on Classical Logic in Philosophia Mathematica, published online on October 27th 2015, a paragraph was included that did not meet the standards for which we aim in the journal. We apologise for this. The review has now been retracted and procedures have been established to prevent similar episodes in the future.
