I suggest everybody to get the must-read work Violence by Slovenian philosopher Slavoj Zizek; you'll find a soft copy (in PDF) with a brief search on Google.
I discuss the concept of "systemic violence" in my "The Problems of Democratic Centralism and their Solutions". To download it, you might conveniently click here!
What to do for the making of a Participatory Front and How to do that
and in the Postcapitalist Manifesto. To download it, you might conveniently click here!
What is Violence?
Among other things, Violence is an intelligent, concise and perceptive critique of the systemic violence (or "the often catastrophic consequences of the smooth functioning of our economic and political systems ") on the part of passive "liberal Communists", court philosophers, philanthropists, hippies, NGOs and "humanitarian activists".
As Slavoj Zizek observes, systemic violence - which is dominant in our social structure - is far more dangerous and ruthless than the 'subjective' isolated violence, a produce of the former.
Zizek excels with his irony, cultural examples, intelligence and politico-economic insight; and provides a precious analysis of various cultural and socioeconomic perverse dynamics of Capitalism.
