“As a young man just beginning to publish some short fiction in the t&a magazines, I was fairly optimistic about my chances of getting published; I knew that I had some game, as the basketball players say these days, and I also felt that time was on my side; sooner or later the best-selling writers of the sixties and seventies would either die or go senile, making room for newcomers like me.”

“I finished my first book seventy-six years ago. I offered it to every publisher on the English-speaking earth I had ever heard of. Their refusals were unanimous: and it did not get into print until, fifty years later; publishers would publish anything that had my name on it.”

“When I began to write fiction that I knew would be published as science fiction, [and] part of what I brought to it was the critical knowledge that science fiction was always about the period in which it was written.”

“From the vantage point of my warm, comfortable spot on mother earth, I could see off into infinite space and the eternity of time. In just a few hours, I thought, some of us are going to make that leap into eternity. And I will be one of the instruments of that voyage. I may also be one of the travelers....It's going to happen sooner or later. But if today is my day-I'm going to have a cup of coffee first.”

“It's kind of like... It's kind of like playin' a basketball game. I am there and the other player is there, and it's just the two of us and I put the other player's body in my van. And I am the winner.”

“People say that writers write for money. From my own experience that's not true. I write for me. I publish for money.”
