Infectious disease exists at this intersection between real science, medicine, public health, social policy, and human conflict. There's a tendency of people to try and make a group out of those who have the disease. It makes people who don't have the disease feel safer.

Margot Livesey, my dear friend, reads all the drafts of what I write, and I read hers. We have an intense working relationship. I've been really lucky to know her. She's a great reader and teacher as well as an astonishingly good writer.

I wanted to be a scientist. My undergraduate degree is in biology, and I really did think I might go off and be some kind of a lady Darwin someplace. It turned out that I'm really awful at science and that I have no gift for actually doing science myself. But I'm very interested in others who practice science and in the stories of science.

All my life, books have felt alive; some more so than people, or rather, some people. Alive - this has to do with me, I know, and not the books - in a way that some people aren't. Alive as teachers, alive as minds, alive as imaginative triggers.

We learn wisdom from failure much more than from success. We often discover what will do, by finding out what will not do; and probably he who never made a mistake never made a discovery.

When psychical phenomena have been as much investigated as physical, love will also receive its cumatology - that is, its science of waves. We shall follow the curves of the emotions through the ages, their movement of rise and fall, the oppositions and side-influences by which they have been determined.

It's not clear in physics why you can't see the future.

My feeling is that scientific method has the power to account for and interlink all phenomena in the universe, including its origin, using the laws of nature. But that still leaves the laws unexplained.
