Alteration is a constructive act, not a destructive one, and it's the opposite of most of our impulses.

As many glaciers are melting and icy tundras are decaying, there's an unprecedented amount of woolly mammoth material that's becoming dislodged from the ice. Not just mammoth, but all kinds of fossils from the past. What occurred to me was, had anyone tried to pinpoint the first case of human-induced extinction? What was the first time we as species pushed another one to oblivion? I would argue that's probably going to be one of the defining moral problems of the century, human-induced extinction. And I really wanted to know, when did we first cross that barrier?

To this day, I've never had an assistant. I really insist on doing everything myself because I value the role of the artist's hand so much in the process. But that means I have to learn it personally in order to do it.

I want the strangeness and weirdness and incomprehensibility of life that art can reflect so well, but I want it to feel like a mystery that is inviting us in. Sagan's great art lesson for me was generosity of wonder and making curiosity contagious.

Even if the effort is bound to fail you still commit completely. It is the commitment that counts for something.

With nothing to risk, love can't exist.
