Mistakes - mistakes - you yourself are a unique mistake!

Of all my children, this is the one that cost me the worst birth-pangs and brought me the most sorrow; and for that reason it is the one most dear to me.

Only art and science make us suspect the existence of life to a higher level, and maybe also instill hope thereof.

I change many things, discard others, and try again and again until I am satisfied; then, in my head, I being to elaborate the work in its breadth, its narrowness, its height, its depth...I hear and see the image in front of me from every angle as if it had been cast and only the labour of writing it down remains.

I alter some things, eliminate and try again until I am satisfied. Then begins the mental working out of this material in its breadth, its narrowness, its height and depth.

Don't regard yourself as too divine to improve, occasionally, your own works.

I know of no more sacred duty than to rear and educate a child.
