“Every work of art is aggressive, Isabella. And every artist's life is a small war or a large one, beginning with oneself and one's limitations. To achieve anything you must first have ambition and then talent, knowledge, and finally the opportunity.”

“Every achievement, every step forward in knowledge, is the consequence of courage, of toughness towards oneself, of sincerity to oneself”

“I think you are talented and passionate, Isabella. More than you think and less than you expect. But there are a lot of people with talent and passion, and many of them never get anywhere. This is only the first step for achieving anything in life. Natural talent is like an athlete's strength. You can be born with more or less ability, but nobody can become an athlete just because he or she was born tall, or strong, or fast. What makes the athlete, or the artist, is the work, the vocation and the technique. The intelligence you are born with is just ammunition. To achieve something with it you need to transform your mind into a high-precision weapon.”

“Having then for the first time clearly understood that before every man, and before himself, there lay only suffering, death, and eternal oblivion, he had concluded that to live under such conditions was impossible; that one must either explain life to oneself so that it does not seem to be an evil mockery by some sort of devil, or one must shoot oneself.”

“I'm putting back into the self the responsibility for the collective life. If each one of us took very seriously the fact that every little act, every little word we utter, every injury we do to another human being is really what is projected into larger issues; if we could once begin to think of it that way, then each one of us, like a small cell, would do the work of creating a human self, a kind of self who wouldn't have ghettos, a kind of self that wouldn't go to war. Then we could begin to have the cell which would influence and enormous amount of cells around you. I don't think we can measure the radius of the personal influence of one person, within the home, outside of the home, in the neighborhood, and finally in national affairs.”

“Every science begins as philosophy and ends as art; it arises in hypothesis and flows into achievement.”
