On a visit to the space program, President Kennedy asked me about the satellite. I told him that it would be more important than sending a man into space. “Why?” he asked. “Because,” I said, “this satellite will send ideas into space, and ideas last longer than men.

If librarianship is the connecting of people to ideas – and I believe that is the truest definition of what we do – it is crucial to remember that we must keep and make available, not just good ideas and noble ideas, but bad ideas, silly ideas, and yes, even dangerous or wicked ideas.

Young men and women are causing wealth loss to their generation because they are sitting on inert ideas, bottled-up potential energy and scratching the ground when they should be gliding the skies and perambulating with the stars. These people are so disillusioned they live life without any urgency.

Have more than one idea on the go at any one time. If it's a choice between writing a book and doing nothing I will always choose the latter. It's only if I have an idea for two books that I choose one rather than the other. I ­always have to feel that I'm bunking off from something.

At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense.

Truth is a matter of the imagination. The soundest fact may fail or prevail in the style of its telling: like that singular organic jewel of our seas, which grows brighter as one woman wears it and, worn by another, dulls and goes to dust. Facts are no more solid, coherent, round, and real than pearls are.

And you realize that there’s no such thing as an individual, we’re just all a collection of each other’s influence on each other. Everyone says things to each other, the television, your parents, your friends, that’s all we are, is a collection of intermingling ideas as a collective.

The movies remind me of the Triangle Club at Princeton. I used to belong to it, and we always started out firm in our decision to create new and startling things. We always ended up by producing the same old show. In the beginning, our enthusiasm and ideals discarded as rubbish all the old fossilized plots.

In all well-organised brains, the predominating idea—and there always is one—is sure to be the last thought before sleeping, and the first upon waking in the morning. Andrea had scarcely opened his eyes when his predominating idea presented itself, and whispered in his ear that he had slept too long.

When a reader falls in love with a book, it leaves its essence inside him, like radioactive fallout in an arable field, and after that there are certain crops that will no longer grow in him, while other, stranger, more fantastic growths may occasionally be produced."[Books vs. Goons, L.A. Times, April 24, 2005]

Ideas begin their life as small seeds, so light they may drift through the air like dust motes. If a human is fortunate enough to catch one, when the light is right, it can be planted, just like a seed. With fertile soil, it may grow into a flower or tree, which will re-seed, thus producing a whole field or forest.

As time went on, we learned to arm ourselves in our different ways. Some of us with real guns, some of us with more ephemeral weapons, an idea or improbable plan or some sort of formulation about how best to move through the world. An idea that will let us be. Protect us and keep us safe. But a weapon nonetheless.

Lo que pasó es lo de menos. Es una novela, y lo que ocurre en ellas da lo mismo y se olvida, una vez terminadas. Lo interesante son las posibilidades e ideas que nos inoculan y traen a través de sus casos imaginarios, se nos quedan con mayor nitidez que los sucesos reales y los tenemos más en cuenta.

I could go on like this forever, but would I ever find a place that was meant for me? Like, for example, where? After lengthy considerations, the only place I could think of was the cockpit of a two-seater Kamikaze torpedo-plane. Of all the dumb ideas. In the first place, all the torpedo-planes were scrapped thirty years ago

The ideas of economists and political philosophers, both when they are right and when they are wrong are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually slaves of some defunct economist.
