Benedict XVI says to scientists of the Pontifical Academy for Life, but works for any scientist:

“The shape that you have given your work manifests that confidence that the Church has always placed in the possibility of human reason and in a scientific undertaking rigorously conducted, which always keep the moral aspect in view.”

Some may wonder, could Benedict XI have said “ethical aspect in view”?
It’s important to understand the difference ..
