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

I am among those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale. We should not allow it to be believed that all scientific progress can be reduced to mechanisms, machines, gearings, even though such machinery has its own beauty.

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained.

All my life through, the new sights of Nature made me rejoice like a child.

The older one gets, the more one feels that the present must be enjoyed; it is a precious gift, comparable to a state of grace

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

This means that we have here an entirely separate kind of chemistry for which the current tool we use is the electrometer, not the balance, and which we might well call the chemistry of the imponderable.
