This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book presents a kaleidoscope of controversies around liberal equality, implying an equal treatment for all, irrespective of sex or gender and not formal equality of opportunity deriving from individuals’ negative rights. It explores 'how the eternal economic laws described by liberal thinkers were rather contingent laws, dependent on capitalism itself'. The book focuses on Post-Structuralism, Feminism and transgender people whose gender identity from the sex assigned at birth is recognized very lately, despite their existence before the last century. It describes the Marxist-Feminist conceptualization of social transformation. The book surveys the methods involved in the institutional reorganization of reproduction in societies aiming at revolutionary transformations, having summed up the three attempted transformations—the Russian, Chinese and Cuban Revolutions.
