Does Christianity retard scientific advancement? Or does it approve of those who help spiritually others who are on the road to perdition, by scientifically removing the environmental causes of the trouble?
Lewis:
Yes. In the abstract it is certainly so. At a particular moment, if most human beings are concentrating only on material improvements in the environment, it may be the duty of Christians to point out (and pretty loudly) that this isn’t the only thing that matters. But as a general rule it is in favour of all knowledge and all that will help the human race in any way.
