Rob Riemen, Dutch philosopher and founder of the Nexus Institute, names Baruch Spinoza, the 17th century philosopher, as one of the first great minds to understand the importance of democracy. Spinoza, he says, saw that only democracy would be able to put human dignity and individual freedom first. But maintaining democracy, Riemen says, is not about institutions. Instead, it relies on cultivating the "spirit of democracy" through liberal education.
