“If we face the fact, for it is a fact, that there is no arm to cling to, but that we go alone and that our relation is to the world of reality and not only to the world of men and women...”

“My belief is that if we live another century or so — I am talking of the common life which is the real life and not of the little separate lives which we live as individuals — and have five hundred a year each of us and rooms of our own; if we have the habit of freedom and the courage to write exactly what we think; if we escape a little from the common sitting-room and see human beings not always in their relation to each other but in relation to reality; and the sky, too, and the trees or whatever it may be in themselves; if we look past Milton's bogey, for no human being should shut out the view; if we face the fact, for it is a fact, that there is no arm to cling to, but that we go alone and that our relation is to the world of reality and not only to the world of men and women, then the opportunity will come and the dead poet who was Shakespeare's sister will put on the body which she has so often laid down.”

“Well, sir. I look at facts. And the fact is that our world is dying and if we don't all do our best to save it, we aren't going to last much longer.”

“Great problems that face the world today in both the private and the public sphere cannot be solved by women – or by men – alone. They can only be surmounted by men and women side by side.”

“We have in fact only two certainties in this world - that we are not everything and that we will die.”

“That's really what SF is all about, you know: the big reality that pervades the real world we live in: the reality of change. Science fiction is the very literature of change. In fact, it is the only such literature we have.”
