Gottlob Frege notably criticized this thinker's psychological treatment of mathematics in his first published work entitled Philosophy of Arithmetic, and after studying under Thomas Masaryck, this man began to extend the ideas of Franz Brentano, a move which led to his development of the technique of epoche, or bracketing. A critique of psychologism in philosophy is contained in this man's "Prolegomena to Pure Logic," which forms the first volume of his most famous work, the volumes of which address topics such as intentionality and cognition. For ten points, identify this founder of phenomenology and author of Cartesian Meditations and Logical Investigations.
