If we make a couple of discoveries here and there we need not believe things will go on like this for ever.... Just as we hit water when we dig in the earth, so we discover the incomprehensible sooner or later
I hope that posterity will judge me kindly, not only as to the things which I have explained, but also to those which I have intentionally omitted so as to leave to others the pleasure of discovery
The only real voyage of discovery consists not in seeing new landscapes, but in having new eyes, in seeing the universe with the eyes of another, of hundreds of others, in seeing the hundreds of universes that each of them sees
On Destiny: "Our destiny exercises its influence over us even when, as yet, we have not learned its nature: it is our future that lays down the law of our today."
