To me the most interesting thing about man is that he is an animal who practices art and science and in every known society practices both together.

Nations in their great ages have not been great in art or science, but in art and science.

We are all afraid for our confidence, for the future, for the world. That is the nature of the human imagination. Yet every man, every civilization, has gone forward because of its engagement with what it has set itself to do.

Science is a tribute to what we can know, although we are fallible.

We receive experience from nature in a series of messages. From these messages we extract a content of information: that is, we decode the messages in some way. And from this code of information we then make a basic vocabulary of concepts and a basic grammar of laws, which jointly describe the inner organization that nature translates into the happenings and the appearances we meet.

There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy.

Science has nothing to be ashamed of even in the ruins of Nagasaki. The shame is theirs who appeal to other values than the human imaginative values which science has evolved.
