What is democracy? Since this deceptively simple question first came into my mind, I haven’t been able to shake it. We think we understand the word, but what are we really referring to when we talk about a system in which the people rule themselves?

The word democracy is all around us, invoked in almost every conceivable context: government, business, technology, education, and media. At the same time, its meaning, taken as self-evident, is rarely given much serious consideration. Though the headlines tell us democracy is in “crisis,” we don’t have a clear conception of what it is that is at risk. The significance of the democratic ideal, as well as its practical substance, is surprisingly elusive.
