It is for reasons roughly analogous to these that I will make an argument for human destiny. Here, as I've said, the argument has to get quite speculative. Neither biological evolution nor human history is a smooth, steady process. Technological, geopolitical, and economic change seem ominously fast, and the fabric of society seems somehow tenuous. Weapons of mass destruction are cultivated by rogue regimes and New Age cults.
Nations seem less cohesive than before, afflicted by ethnic or religious or cultural faction.
Even tropical storms seem to have grown more intense in recent decades, arguably a result of global warming. It sounds apocalyptic, and some religiously minded people think it literally is. Some fundamentalist Christians cite growing global chaos as evidence that Judgment Day is around the corner. In a sense, these fundamentalists are right. No, I don't mean about the Rapture.
