Nature is a tinkerer, not an inventor.

For me, this world of questions and the provisional, this chase after an answer that was always put off to the next day, all that was euphoric. I lived in the future.

One of the deepest functions of a living organisms is to look ahead... to produce future.

The Place of No Shadows, in Isaac Asimovs Science Fiction Magazine (1990) In our Universe, matter is arranged in a hierarchy of structures by successive integrations.

It is hope that gives life meaning. And hope is based on the prospect of being able one day to turn the actual world into a possible one that looks better.

I had turned my anxiety into my profession.

Evolution is a tinkerer.
