"We live in an age dominated by the problem of limits. We are witnessing the end of progress. We have reached the saturation point. Are we going beyond these limits? Are we going to take the risk? There is much work to do to maintain the planet."

“I do not want to heap coals of fire on anyone's head, but I would like to advise those who keep the living thought of the dead hidden away in cardboard boxes, to pass on as quickly as possibly such explosive material, whose only legitimate heir is the whole world, that is to say, my neighbor.”

“Music has to do with sounds, so we need to find them somewhere and it is preferred to find musical ones. You have two sources for sounds: noises, which always tell you something — a door cracking, a dog barking, the thunder, the storm; and then you have instruments. An instrument tells you, 'la-la-la-la.' Music has to find a passage between noises and instruments. It has to escape. It has to find a compromise and an evasion at the same time; something that would not be dramatic because that has no interest to us, but something that would be more interesting than sounds like Do-Re-Mi-Fa...”
