I feel that all knowledge should be in the free-trade zone. Your knowledge, my knowledge, everybody's knowledge should be made use of. I think people who refuse to use other people's knowledge are making a big mistake. Those who refuse to share their knowledge with other people are making a great mistake, because we need it all. I don't have any problem about ideas I got from other people. If I find them useful, I'll just ease them right in and make them my own.
