I think there are certain facts about human beings and about human nature, which tell us that there are definite red lines about how we behave towards other people.

And those objective facts tell us about how we should behave towards them. When we see somebody in pain, somebody suffering, somebody sad, somebody lonely, somebody deprived, that tells us what we need to do, how we might be able to help a little bit. Because those facts are facts that we ourselves experience, we have first hand knowledge of them. They teach us, therefore, about those parameters, those borders, so to speak, within which and beyond which, our moral life and moral action, and our ethical outlook in general, should lie.
