Well, now we have both Rand Paul and Ted Cruz in the lists for President. Of the two, Paul is the more interesting because he is not a militarist, and he favors easing the punishment for drug law violations. This difference will cost him some votes vs. people like Cruz, and might gain him some votes against the Democratic nominee, almost certainly Hillary Clinton.
Paul’s libertarian views are extreme, and show a fundamental misreading of human nature. We are not autonomous individuals, but, inescapably, members of social groups of increasing size, benefitting and being benefited by those groups. The only apes that are autonomous, arguably, are the orangutans of Borneo, the males spending their lives alone except for an occasional mating with a female. The female’s only society is her own offspring. The orang is rather distant from us on the family tree of life. Closer are the gorillas and chimpanzees, all of which live in moderate sized social groups, comparable to those of human hunter-gatherers. We find these apes much more interesting, much more like ourselves. The reason is simple. Like them, we are social animals, and we rely on each other.
Libertarianism and conservatism would deprive us of Social Security, Medicare, and mandatory health insurance, would cut regulations on polluting industries and predatory corporations, let support for the indigent dry up further, privatize public education, sell off public lands, and refuse to deal with climate change and overpopulation. The Republican primaries will wind up selecting somebody to try to put a pretty face on all this. We should avoid being fooled.
