The twenty-second meeting was held January 16-17, 2009, at Northern Kentucky University.  We read from the work of Bernard Bolzano on the foundations of analysis. In particular, we read an English translation of his seminal 1817 paper Rein analytischer Beweis des Lehrsatzes, das zwichen je zwei Werthen, die ein entgegengesetzes Resultat gewahren, wenigstens eine reele Wurzel der Gleichung liege (A Purely Analytic Proof of the Theorem that between and two Values which give Results of Opposite Sign, there lies at least one real Root of the Equation) from Steve Russ' The Mathematical Works of Bernard Bolzano (Oxford U. Pr., 2004).
