“[A]fter I got evicted from the Republican Party, I began reading considerably more of the works of American anarchists, thanks largely to Murray Rothbard…and I was just amazed.When I read Emma Goldman, it was as though everything I had hoped that the Republican Party would stand for suddenly came out crystallised. It was a magnificently clear statement. And another interesting things about reading Emma Goldman is that you immediately see that, consciously or not, she's the source of the best in Ayn Rand. She has the essential points that the Ayn Rand philosophy thinks, but without any of this sort of crazy solipsism that Rand is so fond of, the notion that people accomplish everything all in isolation. Emma Goldman understands that there’s a social element to even science, but she also writes that all history is a struggle of the individual against the institutions, which of course is what I’d always thought Republicans were saying, and so it goes.In other words, in the Old Right, there were a lot of statements that seemed correct, and they appeal to you emotionally, as well; it was why I was a Republican—isolationist, anti-authoritarian positions, but they’re not illuminated by anything more than statement. They just are good statements. But in the writings of the anarchists the same statements are made, but with this long illumination out of experience, analysis, comparison…it's rock-solid, and so I immediately realised that I'd been stumbling around inventing parts of a tradition that was old and thoughtful and already existed, and that's very nice to discover that—I don't think it's necessary to invent everything.”

In Defense of Emma Goldman and the Right of Expropriation (1893)
Context: Miss Goldman is a communist; I am an individualist. She wishes to destroy the right of property, I wish to assert it. I make my war upon privilege and authority, whereby the right of property, the true right in that which is proper to the individual, is annihilated. She believes that co-operation would entirely supplant competition; I hold that competition in one form or another will always exist, and that it is highly desirable it should. But whether she or I be right, or both of us be wrong, of one thing I am sure; the spirit which animates Emma Goldman is the only one which will emancipate the slave from his slavery, the tyrant from his tyranny — the spirit which is willing to dare and suffer.

"A Conversation With Roger Zelazny" (8 April 1978), talking with Terry Dowling and Keith Curtis in Science Fiction Vol. 1, #2 (June 1978) http://web.archive.org/web/20070701010155/zelazny.corrupt.net/19780408int.html#2
Context: Yeah, the mythology is kind of a pattern. I'm very taken by mythology. I read it at a very early age and kept on reading it. Before I discovered science fiction I was reading mythology. And from that I got interested in comparative religion and folklore and related subjects. And when I began writing, it was just a fertile area I could use in my stories.
I was saying at the convention in Melbourne that after a time I got typed as a writer of mythological science fiction, and at a convention I'd go to I'd invariably wind up on a panel with the title "Mythology and Science Fiction". I felt a little badly about this, I was getting considered as exclusively that sort of writer. So I intentionally tried to break away from it with things like Doorways in the Sand and those detective stories which came out in the book My Name Is Legion, and other things where I tried to keep the science more central.
But I do find the mythological things are creeping in. I worked out a book which I thought was just straight science fiction -- with everything pretty much explained, and suddenly I got an idea which I thought was kind of neat for working in a mythological angle. I'm really struggling with myself. It would probably be a better book if I include it, but on the other hand I don't always like to keep reverting to it. I think what I'm going to do is vary my output, do some straight science fiction and some straight fantasy that doesn't involve mythology, and composites.
