Many, but not all, of the Russian Machists were Marxists, and some viewed Machism as an essential ingredient of a materialist outlook on the world.
With a shared desire to defend an "orthodox" account of Marxism, from their own differing perspective they both divided the opponents of this putative orthodoxy into the "idealists" and the "Machists".
[2] It can also be seen in Evald Ilyenkov's chapter on "Marxism against Machism as the Philosophy of Lifeless Reaction" in Leninist Dialectics and the Metaphysics of Positivism (1979).
However whilst many of the proponents of Russian Machism saw it as adding important insights to what a materialist view of the world would look like, Vladimir Lenin was a consistent opponent, writing Materialism and Empirio-criticism to refute their ideas.
Lenin cited as supporters of Machism: Bazarov, Bogdanov, Lunacharski, Berman, Gelfond, Yushkevich, Sergei Suvorov and Nikolai Valentinov.
