I giovani non hanno bisogno di sermoni, i giovani hanno bisogno di esempi di onestà, di coerenza e di altruismo.

Messaggio di fine anno agli Italiani, 1978

Des observations qui précèdent, je crois pouvoir conclure que la photographie, qui marche au premier rang des inventions scientifiques modernes, est au contraire d'une valeur à peu près nulle au point de vue du perfectionnement des beaux arts; que ses produits sont loin de satisfaire aux exigences de la reproduction plastique, et qu'elle ne saurait rendre de services aux dessinateurs et aux peintres que dans des cas très limités

Recover your faith in progress. Realize that the future is already here: in those few shining examples, in agribusiness, in industry, in services, in education, in artificial intelligence, in medical science, and even in social and political experiments where previously unimaginable targets hve been surpassed and new targets continue to fall like skittles. Remember the 80/20 Principle. Progress always comes from a small minority of people and organized resources who demonstrate that previously accepted ceilings of performance can become floors for everyone.
