Everyone knows that democracy is in trouble, but do we know what democracy actually is? Political philosopher Jan-Werner Müller, author of the widely acclaimed What Is Populism? takes us back to basics. In this short, elegant volume, he explains how democracy is founded on three vital principles: liberty, equality, and also uncertainty. The latter, he argues, is crucial for ensuring democracy’s dynamic and creative character. Authoritarians, as well as Big Tech, seek to render politics (and individual citizens) predictable; democracy holds open the possibility that new ideas, movements and identities can be created.
