Language would have evolved first as an internal object, a kind of "language of thought" (LOT), with externalisation (hence communication) an ancillary process. I can't review here the strong and growing evidence to support this conclusion, but I have elsewhere. There are ample reasons why having a LOT would confer selectional advantage: the person so endowed could plan, interpret, reflect, etc., in ways denied to others.

Today, the danger of some sort of a nuclear catastrophe is greater than it was during the Cold War, and most people are blissfully unaware of this danger.

Melting of the huge Antarctic glaciers, proceeding more rapidly than anticipated, threatens a rise in sea level that will drive tens of millions from the low-lying plains of Bangladesh alone, with disastrous consequences elsewhere.

Predatory capitalism created a complex industrial system and an advanced technology; it permitted a considerable extension of democratic practice and fostered certain liberal values, but within limits that are now being pressed and must be overcome. It is not a fit system for the mid-twentieth century.

Prophet just means intellectual. They were people giving geopolitical analysis, moral lessons, that sort of thing. We call them intellectuals today. There were the people we honor as prophets, there were the people we condemn as false prophets. But if you look at the biblical record, at the time, it was the other way around. The flatterers of the Court of King Ahab were the ones who were honored. The ones we call prophets were driven into the desert and imprisoned.

Death and genitals are things that frighten people, and when people are frightened, they develop means of concealment and aggression. It is common sense.

The most dramatic case is that of the Central Americans. Why are people fleeing Central America? It's because of the atrocities the U.S. committed there. Take Boston, where there's a fairly large Mayan population. These people are fleeing from the highlands of Guatemala, where there was virtual genocide in the early 1980s backed by Ronald Reagan. The region was devastated, and people are still fleeing to this day, yet they're sent back.
