Offering a collection of fifteen essays that deal with issues at the intersection of phemelogy, logic, and the philosophy of mathematics, this 2005 book is divided into three parts. Part I contains a general essay on Husserl's conception of science and logic, an essay of mathematics and transcendental phemelogy, and an essay on phemelogy and modern pure geometry. Part II is focused on Kurt Godel's interest in phemelogy. It explores Godel's ideas and also some work of Quine, Penelope Maddy and Roger Penrose. Part III deals with elementary, constructive areas of mathematics. These are areas of mathematics that are closer to their origins in simple cognitive activities and in everyday experience. This part of the book contains essays on intuitionism, Hermann Weyl, the tion of constructive proof, Poincare and Frege.
