The pair of Letters added today to the Journal of 9/11 Studies illustrates how a civil discussion can take place, even when one party is critiquing another's work.

Prof. Mark Vorobej sent a Letter to the Journal of 9/11 Studies which included a critique of some material in Barrie Zwicker's book, "Towers of Deception: The Media Cover-up of 9/11." Of course, the editors allowed Barrie to reply -- a courtesy we extend in all such cases. That is, if one finds his work criticized by another, then he or she has a standing invitation to respond. This invitation stands to all authors who find their work critiqued by another research. And most journals extend the same courtesy -- hence the importance of responding to such authors as Bazant and Seffen... But I digress...

Barrie Zwicker offers a gentlemanly, exemplary response to, and comments upon,
the paper “Cumulative Arguments and Smoking Guns” by Mark Vorobej. He writes:

"I’m personally indebted to the author of “Cumulative Arguments and Smoking Guns” for exposing a weakness in argumentation in Chapter 2 of my book Towers of Deception: The Media Cover-Up of 9/11. My recognition of the author’s superior reasoning in this particular will become evident.

"The paper exhibits two impressive strengths, in my opinion. The first is simply that the author brings philosophy to bear on a highly important topic within current affairs: whether the official narrative of 9/11 is false, true, or somewhere in-between. The last time I studied philosophy in university was 1967-68. My philosophy professor droned on with no application of his philosophizing (until I challenged him) to the Vietnam War, a highly relevant ongoing current affair of the time. The other strength of the paper is the general rigor of the author’s philosophical and logical reasoning."
