“Solidarity: all terms of solidarity still purport the first and most basic solidarity between all humanity (i.e. of “the human”) against nature. Such a solidarity of one against everything else is yet never allowed amongst humans themselves. But there is no such thing as a necessity of solidarity. The idea of us all “sitting in one boat” is an example of this wrong idea of an absolute solidarity.
The concept of a group, with its relatedness of the part-and-whole category, stems from the solidarity of the human against nature.”
