“Our claim is that a common political project is possible. This possibility of course will have to be verified and realized in practice. … We are capable of democracy. The challange is to organize it politically.”

Context: These are not sentimental considerations; they constitute the mechanism of production and therefore of power. Personal liberty is the pre-condition of the release of energy. Private property is the inductor which initiates the flow. Real money is the transmission line; and the payment of debts comprises half the circuit. An empire is merely a long circuit energy-system. The possibility of a short circuit, ensuing leakage and breakdown or explosion, occurs in the hook-up of political organization to the productive processes. This is not a figure of speech or analogy, but a specific physical description of what happens.

Franklin says this line in the HBO miniseries John Adams, but it is actually a quote of Otto von Bismarck.

Context: It may be that we are puppets — puppets controlled by the strings of society. But at least we are puppets with perception, with awareness. And perhaps our awareness is the first step to our liberation. The fact that obedience is often a necessity in human society does not diminish our responsibility as citizens. Rather, it confers on us a special obligation to place in positions of authority those most likely to use it humanely. And people are inventive. The variety of political forms we have seen in history are only several of many possible political arrangements. Perhaps the next step is to invent and to explore political forms that will give conscience a better chance to resist errant authority.

“I’ve come to the same comforting conclusion, old friend. Therefore let’s away—an impossibility can only do us an unreal sort of harm, after all.”
