Jerome Le Jeune

The scientist who identified Trisomy 21 (Down's Syndrome).  Well worth listening to.

“it is not medicine we should fear, but the folly of mankind. Every day, the experience of our predecessors increases our ability to change nature by using his own laws. But using this power wisely is what each generation must learn in its turn. We are certainly more powerful today than ever before, but we are not wiser: Technology is cumulative, wisdom is not;”

“We need to be clear : the quality of a civilization can be measured by the respect it has for the weakest members. This is no other criterion.”
