Understanding the laws of nature does not mean that we are immune to their operations.

I have a very simple philosophy of life: Kindness. Ferocious, unrelenting, ruthless, committed, passionate, kindness. Life is sacred everywhere. We all have better things to do than beat each other up. Arguing for the exception is to invest it with energy, it's to negotiate the loophole. The commitment to kindness must be total.

True genius can be identified by the fact that its expression changes the world into something it has never been before.

I have memories - but only a fool stores his past in the future.

I'm frustrated with Hollywood and television and the movies because they see science fiction as an excuse for eye candy, for lots of great special effects.

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.

It's almost always dangerous to be right too soon.
