"Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less."
"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."
