The present collection of papers and critical studies by Prof. Guillermo E. Rosado Haddock under the title Unorthodox Analytic Philosophy brings together both older studies and recent papers on Husserl, Frege, Carnap, Kant and other philosophers, as well as contributions of the author to central problems in the philosophy of logic, the philosophy of mathematics, and semantics. All papers are written in the tradition of rigorous philosophy, conscious of the developments of the more exact sciences, but completely free from the prejudices of empiricist and anti-Platonist ideology.
