Torcello is an associate professor of philosophy at the Rochester Institute of Technology.
Plato, one of the earliest thinkers and writers about democracy, predicted that letting people govern themselves would eventually lead the masses to support the rule of tyrants.
When I tell my college-level philosophy students that in about 380 B.C. he asked "does not tyranny spring from democracy," they're sometimes surprised, thinking it's a shocking connection.
But looking at the modern political world, it seems much less far-fetched to me now. In democratic nations like Turkey, Great Britain, Hungary, Brazil and the United States, anti-elite demagogues are riding a wave of populism fueled by nationalist pride. It is a sign that liberal constraints on democracy are weakening.
