Karl Popper's Optimism - A Duty !

Is it hard to be an optimist today? A discussion on why Popper was an optimist and why he saw it as a duty. Hopefully some of Popper's ideas can help you become more optimistic and help make the world a better place. As always, some material will be provided to stimulate discussion. I will aim to get the material out before the Meetup. And as per each Meetup, will head to the Civic Labour Club after the meet for a coffee/drink and continued discussion. Cheers, Todd
