 You know, science and arts are very much in common. They are both creative, imaginative, exciting, looking for the future. Science and arts, they are both universal. Mathematics, physics, biology, painting, music, dancing. They speak all the languages. But why do we need arts to help us, scientists, to communicate this complex, difficult message to develop and propose sustainable futures? You know, many of us scientists believe that hard facts, which science is producing, a lot of technology, a lot of new innovations, will bring us to the course of sustainable future. But it's not enough. We also need to understand how these institutions, which humans created, how the humans themselves, our behavior, will change. The behavior of you and I, this emotion, that's what we feel. That's how we move ourselves ahead, deep inside ourselves. And this is where the arts is coming into the play. So imagine, coming back to Mahler from the first part of this evening, you are on this fish in the ocean, and you are listening to me here, giving your lecture with photographs about how to change the energy systems or whatever. I think the chance that you will be untouched by this fish is a big one. As opposed to having me here and others and this fantastic artist, musician and dancers, whom I appeal to your emotion, when you close your eyes and listen to music or look how they dance. Imagine a woman getting out of poverty, a child going to school. And that is touching you in your heart that I am sure that you will be fish leaving this place very much changed.
