Bob Brown stood head and shoulders above the leaders of other parties in this country, morally, intellectually and philosophically. I've been lucky enough to meet him very briefly a couple of times, and he has a warmth and sincerity which immediately draws you to him.
Memo for a Saner World is a collection of disparite thought, though with a clear call within it for a more understanding and ecologically sound world. Detailing some of Bob Brown's struggles thoughout the years, he has risked his own safety for higher causes, and has had some stunning successes.
For those seeking a deeper understanding of what the Green party is all about, I recommend Memo for a Saner World. For those who are already in the party and are committed environmentalists like myself, there are probably better books to read.
