Sloth, however, has its virtues. It speaks of a time that belongs to us. Many artists, scientists and scholars claim that some of their best insights arrived when idle, day dreaming or taking a walk. We might restore the sense of sloth that is, according to historian Aviad Kleinberg, optimistic. It respectfully encourages fellow citizens to enjoy a sense of free time without designed purposes and lasting rewards. And this enjoyment is unplugged to Internet, auto traffic and work.
