I am the place in which something has occurred.

Scientific knowledge advances haltingly and is stimulated by contention and doubt.

Our students wanted to know everything: but only the newest theory seemed to them worth bothering with. Knowing nothing of the intellectual achievements of the past, they kept fresh and intact their enthusiasm for 'the latest thing'. Fashion dominated their interest: they valued ideas not for themselves but for the prestige that they could wring from them.

Objects are what matter. Only they carry the evidence that throughout the centuries something really happened among human beings.

I hate travelling and explorers

The scientist is not a person who gives the right answers, he is one who asks the right questions.

How can my old photographs fail to create in me a feeling of emptiness and sorrow? They make me acutely aware that this second deprivation will be final this time.
