"I do indeed believe that there is a certain contrast between, say, people in scientific professions and people working in the arts. Often there is even mutual suspicion and irritation, and in some cases one group greatly undervalues the other. Fortunately there is no one who actually has only feeling or only thinking properties. They intermingle like the colors of the rainbow and cannot be sharply divided. Perhaps there is even a transitional group, like the green between the yellow and the blue of the rainbow. This transitional group does not have a particular preference for thinking or feeling, but believes that one cannot do without either the one or the other. At any rate, it is unprejudiced enough to wish for a better understanding between the two parties... It is clear that feeling and understanding are not necessarily opposites but that they complement each other."

“..and to think now that great mathematicians find my work interesting because I am able to illustrate their theories. They can not imagine that I was such a bad pupil in mathematics. I don't understand it myself neither. I never could understand why it was necessary to prove something that everyone already sees. I saw it, I knew it, so it is how it is… But yes, you had to prove it. I did overcome it when I realized I can make something else - I thought I was a good-for-nothing. In my family there were no other artists to find.. .I was just a weird duck, right?”

“The unknown mountain nests in the inhospitable interior of southern Calabria are usually connected only by a mule track with the railway that runs close to the coast: whoever wants to go there has to walk on foot if he has no donkey at his disposal. I think back to that warm afternoon in the month of May when we the four of us, after a long, tiring ride in the harsh sun, packed with the heavy burden of our backpacks, sweat-dripping and a little gasping, entered the city gate of Palizzi..”

“When someone forgets himself, this by no means makes him altruistic; when a thinking person forgets himself, he immediately also forgets his fellowman, he loses himself and his humanity by becoming engrossed in his subject. Thus he is in a sense more contemplative than a feeling person.”
