We have advanced the thesis that the first half of The Philosophy of Living Experience is introductory in that it prepares the reader for the discussions of Marx and Mach and the exposition of Bogdanov's own worldview in the second. It could also be argued that the chapters on empiriocriticism and dialectical materialism are introductory as well. In them, Bogdanov's principal intent was to dispose of Marx and Mach in the manner of his treatment of earlier thinkers. For one reason or another, he deemed their philosophies unsuitable, obsolete solutions to the contemporary problem of philosophy.
