The foundation and root of the entire Torah is to raise and exalt the soul over the body.

— Rabbi Schneur Zalman

If economic materialism takes precedence over the claims of biology within Marxism, then an economic, materialistic view of human beings can take precedence over the claims of biology within Marxism. If humans are material things, then humans can have advanced industrial production techniques applied to them. If Marx’s materialistic objectification of the world were total, this implied that humans could be treated not only as the subjects of economic processes, but also as the objects of economic processes.

And this is where the materialist logic of Marxism breaks down.

Auschwitz, then, can be viewed as a legitimate implication of Marxism. The Judeocide can be viewed as a possible logical solution to the Marxist elimination of all biological factors so that humans can be viewed purely as material factors in economic-industrial processes. A strictly Marxist view of Auschwitz is thus possible as an extreme implication of economic materialism; a consistent economic materialism.

— Jewish author Mitchell Heisman, from his 2010 book entitled "Suicide Note"
