Joseph Fletcher

• He did not advocate an 'anything goes' approach to genetic engineering
• The proper controls to prevent abuse and exploitation must be in place. But otherwise, although many of the above techniques that are currently available or on the horizon were only a distant possibility in his day, he viewed them positively
• Rules and principles based on outdated and irrelevant biblical texts or religious dogma should be set aside
• He foresaw a time in the future when overpopulation or shortage of natural resources would necessitate the genetic modification of humans to enable them to live in the vastly different conditions of space
