I am among those who think that science has great beauty.

Each of us must work for his own improvement, and at the same time share a general responsibility for all humanity.

I was taught that the way of progress was neither swift nor easy.

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

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.

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves.
