Arthur Conan Doyle

The idea of copyright did not exist in ancient times, when authors frequently copied other authors at length in works of non-fiction. This practice was useful, and is the only way many authors' works have survived even in part.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.

If you're a filmmaker, and every time you finish a film, you just naturally go, 'Oh, I could have done so much better,' that's not much fun, is it, really? You might as well go pick another profession if that really is how you derive satisfaction from it.
