This video attempts to take on the claim that you can't get an "ought" from an "is". (in other words, you can't derive how you should behave based on plain, non-prescriptive facts about the universe.) It's funny because I completely disagree with so much of his reasoning but I definitely agree with the conclusion.
Harris essentially makes an unfounded assertion, doing the same thing that theists do when they confuse universality with absoluteness. That is, "we all feel a certain way morally about X, therefore X must be an absolute moral truth."
But I've always argued against the "ought"/"is" problem also. The problem is that, implicit in the claim "You can't get an 'ought' from an 'is'" is that there exists an absolute "ought". The premise is flawed to begin with. You can't get an "ought" of this sort from anything because the entire concept is nonsensical. What you can get, however, is the type of ought that does exist: an "ought-for" or "ought-if". That is, given some end/value, you can at least theoretically use science and reason to derive the best way to achieve it. Similarly, you can use science/reason to determine what it is that we value, by and large. Clearly we won't all value the same things, but given our extremely similar biology and the influences which shaped it, we agree much more than we disagree. And additionally, science and reason can serve to filter our moral behaviors that don't have any ground to stand on in the first place, e.g. "turn your pillowcase opening away from your bed so the evil spirits will pour off to the side." (This is not a joke; this is an actual superstition practiced and feared by the very religious mother of someone I know, who also panics during any thunderstorm, honestly fearing it may be the Rapture.)
