Are experiments on human life, like artificial birth and organ exchange, considered an advance or an action against nature?

According to Osho, experiments on human life are not inherently against nature; they are neutral tools. What matters is who directs them and to what end. In the hands of politicians or dogmatic religions, they become anti-nature; guided by an international academy of responsible, nonpartisan scientists serving humanity, such advances—artificial birth, organ and even brain transplants—are nature’s growth and a profound progress.
