This Equals That
Lansing, Michigan, 1976-1980

The community spirit has always been the principal, necessary force for the progress of the revolution. This progress is embodied in the development of solidarity, of mutual relations between workers, of unity. Their organisation and their growing power are the new characteristics which are forged in the struggle (...) The virtues of solidarity and zeal, the impulsion to act as a solid unity engendered by the social struggle, are the very basis of the new social system which will rest on work in common.

Pannekoek, The Workers’ Councils, 1941
