I can’t help but think that the concepts of human nature – of kindness, of justice, of human essence and its realization… These are all notion and concepts that have been created within our civilization, our system of knowledge and our form of philosophy and as a result they form part of our class system. And one cannot, however regrettable it may be, put forward these concepts to describe or justify a fight which should and shall in principle overthrow the very fundamentals of our society.
