Consider a society of a finite number of individuals (1, 2,... n) facing a finite number of states (i.e. alternatives), Z₁, Z₂, … Zₜ (t ≥ 3). Every individual in this society is always able to unambiguously rank all these states with each other. We say that an alternatives Zₖ is Pareto optimal, iff, (A) Every individual in the society considers Zₖ to be superior to any other state (B) Every individual in the society considers Zₖ to be at least as good as any other state (C) There is no other state which is considered at least as good as Zₖ by everyone and strictly better than Zₖ by at least one individual. (D) Every individual in the society considers Zₖ to be at least as good as any other state and with respect to every other state, Zᵢ (i ≠ k), there is at least one individual who strictly prefers Zₖ to this state Zᵢ.
