“My husband and I were so closely united by our affection and our common work that we passed nearly all of our time together.”

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

One never notices what has been done; one can only see what remains to be done.

We must keep our certainty that after the bad days the good times will come again.

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

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

A scientist in his laboratory is not a mere technician: he is also a child confronting natural phenomena that impress him as though they were fairy tales.

You will find that one special love that you know is right but for some reason just doesn’t last.

Be less curious about people and more curious about ideas.

In science, we must be interested in things, not in persons.

You cannot hope to build a better world without improving the individuals.

Life is not easy for any for us.

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

It is my earnest desire that some of you should carry on this scientific work and keep for your ambition the determination to make a permanent contribution to science.

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

More and more, I feel the need for a house and a garden.

All that I saw and learned was a new delight to me.

A scientific man ought to have no wishes, no affections, – a mere heart of stone.

The proof of a poet is that his country absorbs him as affectionately as he has absorbed it.

Books so special and rare and yours that advertising your affection feels like a betrayal.

Citizens by birth or choice of a common country, that country has a right to concentrate your affections.

If a man can be properly said to love something, it must be clear that he feels affection for it as a whole, and does not love part of it to the exclusion of the rest.

I always had the deepest affection for people who carried sublime tears in their silences.

To feel the affection that comes from those whom we do not know, widens out the boundaries of our being, and unites all living things.

The way to change others’ minds is with affection, and not anger.
