I was at a training given by PSI recently and the professor, Mr Barry Deutsch, said something simple but so true :

you have to talk about the future to build the future

Also, during a debate on the challenges of the future of the world on Europe1,Albert Jacquard said : "Nous n'avons qu'un seul outil pour influencer le futur de notre planete : la parole". (which I try to translate like this : "we have only one tool to improve the future of our planet: the words")

That's what Jesus tried, is't it ?
