Ideas: Putting Your Life on the Line for Your Beliefs

This week in Ideas we explore what it is that makes people like the brigadistas risk their lives for their beliefs. First we hear from historian and writer Mark Derby who edited the recently-releasedÂ'Kiwi Companeros: New Zealand and the Spanish Civil WarÂ'. Then later in the programme Christchurch playwright Sam Fisher tells us what motivated him to travel to Sri Lanka to work as a human-shield in the 1990s.
