A work of art is an act of love. Critics are crab lice.

Morality—like velocity—is relative. The determination of it depends on what the objects around you are doing. All one can do is measure one's position in relation to them; never can one measure one's velocity or morality in terms of absolutes.

My approach to 'Star Trek' was, 'I know science fiction, and I know screen writing.' That was very arrogant of me, but you really need to be a little bit arrogant to think that what you have to say is good enough to justify the expense of hundreds of thousands - now millions of dollars - to make an episode of the TV show.

What I wish is that people would look beyond the tribbles and see I've written some other books that I really would like people to notice. There's The Man Who Folded Himself, there's The Martian Child, which is about my son and the adoption. There's The War Against The Chtorr, which is my magnum opus, my great epic story.
