“Humankind does not submit passively to the power of nature. It takes control over this power. This process is not an internal or subjective one. It takes place objectively in practice, once women cease to be viewed as mere sexual beings, once we look beyond their biological functions and become conscious of their weight as an active social force. What's more, woman's consciousness of herself is not only a product of her sexuality. It reflects her position as determined by the economic structure of society, which in turn expresses the level reached by humankind in technological development and the relations between classes.

The importance of dialectical materialism lies in going beyond the inherent limits of biology, rejecting simplistic theories about our being slaves to the nature of our species, and, instead, placing facts in their social and economic context.”
