I always divide people into two groups. Those who live by what they know to be a lie, and those who live by what they believe, falsely, to be the truth.
When all is said and done, we exist only in relation to the world, and our senses evolved as scouts who bridge that divide and provide volumes of information, warnings and rewards.
Another factor is the decision, made in 1976, to sharply divide the FBI and the foreign intelligence agencies. The FBI would collect within the United States; the foreign intelligence agencies would collect overseas.
What I've been surprised by is not how different people are, but how similar they are. There are certain types of Airbnb people, and they are in every city in the world - it's just that in some cultures, there is more of a generational divide.
I sometimes detect that a type of regional divide is setting in, and there is a lack of real Caribbean connection among the islands, and I am concerned about this.
