Participation is meaningless without communication. Just as the Athenian leader Pericles communicated with his citizens in his famous Funeral Oration, so must we communicate with one another to take and coordinate human action through human cooperation. Communication is not possible without a space in which to communicate. The basis of participatory democracy must be communication and action taken together in a public space. We must therefore have more public spaces for democratic participation by everyone, including those among us who have been excluded, who have been marginalized and invisible. Within these public spaces for participation, communication must occur through deliberation with people coming together and talking things through on fair and equal terms to arrive at a mutual decision based on mutual rational criticism. This deliberation must include everyone, and it must be face to face. Local experiments throughout the world have shown that this can be done. By using an ancient sortition machine they called the kleroterion, the ancient Athenians showed how the collective wisdom of the people can be summoned and employed in making public decisions. They also learned through hard experience – exemplified in the trial and execution of Socrates – that collective wisdom and collective action through democratic decision-making are best when the decision-makers are educated to be the best citizens and make the best decisions.
