We seem to be losing that latter skill, the ability to interact with one another. It's a fascinating time that we have lost our belief in the value of diversity of opinion. And i want to make another point on this, which is imitation. You need to look at what other people are doing and imitate it. Skinning not just about an incentive for survival, but putting one's life on the line. The more we're talking about abstract things,. the more we cano hold false belief and live in dangerous beliefs.
