First published in Germany in 1918, this acutely reasoned treatise
attacks many of philosophy's contemporary sacred cows, including the
concept of metaphysics and Kant's arguments for synthetic a priori
knowledge. The book expounds most of the doctrines that would later be
identified with the "classical period" of the Vienna Circle. Unlike many
of his peers, Schlick displays a detailed and sensitive knowledge of the
traditions he criticizes, displayed here in the chief work of this
pioneering Viennese philosopher.
