“I am one of those who think like Nobel, that humanity will draw more good than evil from new discoveries”

“To love for the sake of being loved is human, but to love for the sake of loving is angelic”

“When a man is treated like a beast, he says, 'After all, I'm human.' When he behaves like a beast, he says 'After all, I'm only human.'”

“Are there not thousands in the world who love their fellows even to the death, who feel the giant agony of the world, and more, like slaves to poor humanity, labor for mortal good?”

“Humanity needs practical men, who get the most out of their work, and, without forgetting the general good, safeguard their own interests. But humanity also needs dreamers, for whom the disinterested development of an enterprise is so captivating that it becomes impossible for them to devote their care to their own material profit.”

“There is a road from the eye to heart that does not go through the intellect.”
