I have to agree with Jack that the ice cream example is flawed. I think
the authors had in mind an argument that if (p -> q) and (q -> p) are
true, then p and q are logically equivalent. I don't see how that would
relate to modus ponens. The example is unfortunate. I wouldn't go as
far as Jack has and generalize that one should not take seriously
anything the authors have to say about proof.

The Editorial Panel of the _Mathematics Teacher_ seems to recognize that
the role and nature of proof in a Standards-based curriculum merits
reexamination. On p. 174 of the February 1997 issue, there is a call
for manuscripts addressing the role of proof. A Focus Issue is planned
for fall 1998. The call contains 15 questions that authors might
address. Those with ideas on proof in secondary school mathematics
should consider writing for this issue.
