To sum up [Trotsky wrote], “the road to Socialism lies through a period of the highest possible intensification of the principle of the Slate … The State, before disappearing, assumes the form of the dictatorship of the proletariat, i.e. the most ruthless form of State, which embraces the life of the citizens authoritatively in every direction” ([The Defence of Terrorism] p. 157). It would be difficult indeed to put the matter more plainly. The state of the proletarian dictatorship is depicted by Trotsky as a huge permanent concentration camp in which the government exercises absolute power over every aspect of the citizens’ lives and in particular decides how much work they shall do, of what kind and in what places. Individuals are nothing but labour units. Compulsion is universal, and any organization that is not part of the state must be its enemy, thus the enemy of the proletariat. All this, of course, is in the name of an ideal realm of freedom, the advent of which is expected after an indefinite lapse of historical time. (pg. 512)

Carnap made a detailed analysis of Heidegger’<nowiki/>s statement, “Nothing nihilates,” in order to show that it is purely verbal, devoid of empirical meaning. (Incidentally, this is the only sentence from existentialist philosophy the majority of contemporary positivists appear familiar with.)
