The Bulletin of the Institute of Mathematical Statistics has published a column of mine that deals with the historical and theoretical connections between democracy and statistical sampling:

Democracy and statistical sampling
For about 2,500 years, statistical sampling was closely linked with democracy. “Selection by lot is natural to democracy, as that by choice [i.e., elections] is to aristocracy,” asserted Aristotle in the 4th century BC, following his own first-hand experience at Athens and the conventional wisdom of his time. Montesquieu concurred in the first half of the 18th century. It was only in the last 200 years, as democracy displaced aristocracy as the legitimate organizing principle of politics, that sortition—the delegation of power by statistical sampling—had to be air-brushed out of history and political science. […]
As part of the attempt to dismiss sampling as a political device it is sometimes claimed today that its use in Athens was motivated by the superstition that randomization allowed the gods to make the selection. However, the historical record indicates that the main motivation behind the practice was the law of large numbers. It was expected that sortition would produce a group that would mirror the population in important respects. This was often stated as an expectation of resemblance between the population and the sample in terms of wealth and social status (i.e., that most members would be poor commoners) but it was taken for granted that these characteristics would be correlated with certain interests and beliefs.

Personally, I do not dispute the utility of the senate, even if some changes could surely be considered. There are three reasons for the utility of a second chamber. First of all, a logical reason. The parliament represents the nation, and the nation is the people but also something else. The people are represented by the assembly and other thing, in our system, is the regions (territories). In countries which made the choice of bicameralism, this other thing can be different, for example in England the history of the British nobility is incarnated in the House of Lords, or the civil society in Ireland.
05. The question today is that of rethinking forms of organization, ways of being together for the long term, outside of the electoral forces.
