"If communism means anything at all, it means the radical eruption of democracy. Bursting its present narrow political confines, where it is allowed to hold truncated and partly illusory sway, democracy is to engulf all spheres of social life."
~Moshe Machover, "Collective Decision-Making and Supervision in a Communist Society"
" I swear the neighbours must have heard the facepalm I just made."
~Majakovskij
