I think that without imagination we can go nowhere. And imagination is not something that’s just restricted to the arts. Every scientist that I have met who has been a success has had to imagine. You have to imagine it possible before you can see something, sometimes. You can have the evidence right in front of you, but if you can’t imagine something that has never existed before, it’s impossible. And, with imagination, there are a lot of other characteristics I think you need too. You need determination, and you need to have some sense, some faith in the human ability to persevere and to triumph. Whether you have faith in yourself as that human being is a different point, but at least the faith that human beings can do it. But imagination, in a certain way, contains all of those things, too, because you have to imagine that it is possible for human beings to do something before you can do it.
