After the recommendation by Prof. Dieter Raffler back last summer to read the book “think yourself – instructions to oppositions” by Harald Welzer I was grateful to have finally found a public figure who speaks the truth about the failure of our system, the need for each single person to start and get our hands dirty and especially to become active opposers of obvious manipulation that only serves the profit of the few while destroying our environment and resources. And so of course, I had to go and see him in person in the old library at UdK. Welzer is a very smart and eloquent social scientist who knows how to lead (and win) a discussion. However, the victory went to one student who pointed out that while we all sit here and talk about sustainability, why do we need to have all the light bulbs turned on in the room, this said, he turned half of the light off and earned a big applause. I highly recommend to read this book and spread the word. My students in Dessau were very inspired as well.
