Hoppe: The principle of nonaggression

‎"To argue so, in fact to argue at all, in favor of or against anything, be it a moral, nonmoral,empirical, or logico-analytical position, it must be presupposed that contrary to what the norm actually says, each individual’s integrity as a physically independent decision-making unit is assured. For only if everyone is free from physical aggression by everyone else could anything first be said and then agreement or disagreement on anything possibly be reached. The principle of nonaggression is thus the necessary precondition for argumentation and possible agreement and hence can be argumentatively defended as a just norm by means of apriori reasoning." - Hans-Hermann Hoppe
