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

If it takes a hundred years, it will be a pity, but I will not cease to work for it as long as I live.

It was like a new world opened to me, the world of science, which I was at last permitted to know in all liberty.

You cannot hope to build a better world without improving the individuals. To that end each of us must work for our own improvement, and at the same time share a genaral responsibility for all humanity, our particular duty being to aid those to whom we think can be most useful.

Life is not easy for any for us.

Now is the time to understand more, so we 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.
