I found this talk quite interesting. I had literally no idea who Sam Harris is while watching this video, but I have since learned that he is an avowed atheist who has written some fairly popular books critical of Christian faith. While I would fully disagree with his false opinion that there is no God, I do agree with quite a bit of what he said in this talk.
It sounded to me a lot like this scientist/philosopher was imploring the educated people in the room to finally admit that there is such a thing as absolute morality, which in my mind is a reflection of the fact that there is absolute truth. Perhaps in his endeavors to convince fellow scientists to begin expressing their beliefs in firm statements of truth, Mr. Harris will be granted the understanding that these universal moral truths have an Author who created the universe in which they exist.
This article nicely captured these points from the talk:
We should not feel constrained to assert what we think is an objective truth — that such behavior is wrong — for fear that it will be taken as subjective meddling or demagoguery, Harris argued. There is a moral imperative not to hold one’s tongue but rather to speak out.(HT: Abraham Piper)
We can no longer respect and tolerate vast differences of opinion of what constitutes basic humanity any more than we can take seriously different opinions about how disease spreads or what it takes to make buildings and airplanes safe, Harris insisted.
