Edmund Husserl's views on logic, mathematics, and semantics have been either largely ignored or inaccurately rendered by other philosophers. In Husserl or Frege?, Hill and Haddock break new ground in examining Husserl's ideas in relation to those of Georg Cantor, creator of set theory, analytic philosopher Gottlob Frege, and mathematician David Hilbert. This collection of essays offers a fresh and provocative alternative to contemporary mainstream philosophy of mathematics, and covers key areas of disagreement between Husserl, the father of phenomenology, and Frege, the founder of analytic philosophy.
