It seems only fair to remark that the invective directed against the book by some Amazon customers is something profoundly different in kind from what one finds in reviews by authoritative people. See, for example, the detailed reviews by Ed Waymire in American Mathematical Monthly, Vol. 110, 2003, pp. 964-967, and by Marjorie Hahn in Computing in Science and Engineering, Vol. 6, 2004, pp. 85-88. In forty years of teaching probability theory, I have had very many students who would not have found a book such as this particularly challenging, but who would have welcomed what challenges it does pose.
