“The only thing binding individuals together is ideas. Ideas mutate and spread; they change their hosts as much as their hosts change them.”

“Love simply is where it is. My host loved Curt’s host, and that love did not die when the ownership of the minds changed.”

“You can’t crush ideas by suppressing them. You can only crush them by ignoring them. By refusing to think, refusing to change.”

“I wonder where you got that idea from? I mean, the idea that it's feeble to change your mind once it's made up. That's a wrong idea, you know. Make up your mind about things, by all means - but if something happens to show that you are wrong, then it is feeble not to change your mind, Elizabeth. Only the strongest people have the pluck to change their minds, and say so, if they see they have been wrong in their ideas.”

“Since many things we see were once an idea, let us create good ideas today because they will be the realities of tomorrow! When you create an idea, do not forget that you shape the future! Idea is your God side! With ideas, you can change the universe, but only with very great ideas!”

“Many people have ideas on how others should change; few people have ideas on how they should change. ”
