Nature draws no line between living and nonliving.

In thinking about nanotechnology today, what's most important is understanding where it leads, what nanotechnology will look like after we reach the assembler breakthrough.

Likewise nanotechnology will, once it gets under way, depend on the tools we have then and our ability to use them, and not on the steps that got us there.

My work at MIT had focused on what we could build in space once we had inexpensive space transportation and industrial facilities in orbit. And this led to various sorts of work in space development.

The basic parts, the start-up molecules, can be supplied in abundance and don't have to be made by some elaborate process. That immediately makes things simpler.

I had been impressed by the fact that biological systems were based on molecular machines and that we were learning to design and build these sorts of things.

On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer speeds.

In a sense, artificial intelligence will be the ultimate tool because it will help us build all possible tools.

Scientists study physical things, then describe them; engineers describe physical things, then build them.

...Local prohibitions cannot block advances in military and commercial technology... Democratic movements for local restraint can only restrain the world's democracies, not the world as a whole.

Any powerful technology can be abused.

As artists give themselves to their models, and poets to their classical pursuits, so must we addict ourselves to prayer.

People who achieve big things are those who decide to try ideas that were previously rated and graded as impossibilities. “Impossibility” never exists!

A smile to someone could make the difference between them going home and axe murdering their family or having a nice meal!

The conductor must breathe life into the score. It is you and you alone who must expose it to the understanding, reveal the hidden jewel to the sun at the most flattering angles.

For sale. Baby shoes. Never worn.

To know and not to use is not yet to know!

The lake at Neverland is right in the very front, and you just want to dive in.

Am I melancholy? I certainly have moments. I like to think there's a capacity for joy as well.

At evening casual flocks of pigeons make Ambiguous undulations as they sink Downward to darkness, on extended wings.
