Pride is the problem. At least for Hythloday it's that simple. In Utopia, Hythloday sees Pride as public enemy #1, the main contributor to every political, social, and economic issue facing Europe. Poverty? Pride's fault. Bad kings? You guessed it, Pride. Even though you might think of pride as just one of those seven deadly sins, Hythloday goes out of his way to claim that it's at the root of all other sins. And guess what makes Utopian society so successful? Pride is never rewarded, so it doesn't really exist. Problem solved… maybe.
Hythloday is wrong; pride may not always be great but it isn't all bad. In fact, having some pride is necessary in order to accomplish good things.
Hythloday is the one with the pride problem here, not the rest of Europe. Can you get much prouder than believing you're right and everyone else is wrong?
