Humans, I tell you dear fellow human, are unique. Here’s a quick reminder on our zoological classification.

At the most specific classification — the species level at the bottom of the zoological taxonomic tree — we are homo sapiens, the modern humans. One level up from our species is the genus. We are in the genus homo. We are the only species in that genus.

Go up one level, we belong to the family hominidea. Our family includes chimpanzees, gorillas, and orangutans — the other great apes. We can detect the family resemblance. Apes have large brains and are bipedal.

Apes like us belong to the order primates. Besides us humans, the primate order includes apes, monkeys, and lemurs — animals that have a large brain, and they use their hands to manipulate objects. There are over 500 species of primates in the world. Continue reading “Diversity”

Thanks to Akshay for his comment. From it, I learned something important (see the end of this post.) I love pushback because then I get off my lazy ass and actually write a post.

Both Carl Sagan and Freeman Dyson are excellent exemplars of people who are both well-informed and well-meaning. I would add that they were not just highly intelligent but were also exceedingly wise. However they differed in their assessment of how critical the climate change issue was. This is not surprising because the matter is one on which reasonable people could disagree. It is important to note their divergent opinions and explain it. Continue reading “Experts”

Having lived most of my adult life in the San Francisco Bay area, I naturally think of it as home. I’ve been a citizen of California for decades.

I have made life-long friends here, worked here, gone to graduate school here, taught at various universities here, owned a home here, vacationed in the many national parks here. In short, I am a Californian. Therefore seeing what’s happening to it is distressing, to say the least.

Why the decline and fall of California? Questions about complex phenomena that begin with “why” are “over-determined” (as economists are fond of saying.) There are multiple causal factors, none of which are individually sufficient but various different combinations of them could be responsible. These factors could be economic, technological, social, cultural or historical. Analysis of complex phenomena is never entirely settled. In other words, it’s not rocket science; it’s social science.

On Fridays once in a while I engage with a few teenagers and a couple of my adult friends. We discuss matters of mutual interest. Lately it’s been about climate change and global warming.

I am persuaded that the young are being systematically misled by a committed group of interested parties that have an agenda to profit from misdirection and misinformation.

The image of a TV meteorological report at the top of this post exemplifies my point about misdirection.The top part is colored green and the bottom part red. They are five years apart. The impression conveyed is that the world is melting due to high temperatures but if you care to notice, you’d see that the temperatures reported are pretty much the same.

This has to be resisted. In the following, I present a bit of what I recently wrote to the group of teenagers I engage with on Fridays. Here it is, for the record. Continue reading “Learn Before We Act”

Today was the coronation of King Charles III of the UK. Pretty big day for some people — around 130 million of them who have him as the head of 15 countries, including Canada, Australia, New Zealand, Papua New Guinea, Jamaica, etc.

But we’d have to admit not all of them are his loyal subjects. Celtic fans at the Scottish Cup Semi-finals at Hampden Park last week sent a clear message to his royal highness (note the lack of capitalization). They were not pledging their loyalty. Instead they told him what to do with his coronation. Continue reading “Coronation”

I concluded the post on well-being with: “The trend of increasing wealth, income and consumption is undeniable. The question is what is the trend in inequality? And what of well-being? While the level of well-being is undoubtedly rising around the world, is it also becoming more unequal?”

The world is unequal in terms of wealth and income for certain. Empirical evidence shows that inequality in wealth and income is increasing monotonically. Since wealth and income are positively correlated with consumption, and are also causally linked, one can conclude that inequality of consumption must be growing as well. It is.

That much is clear. Now let’s talk about well-being. What is it? It’s a feeling of being well. It’s about having our needs — physiological, psychological, emotional — satisfied. These needs are met through consumption. We consume water to meet the physiological need to satisfy thirst, for instance. We need stuff to meet our needs; stuff that may be in short supply relative to demand. Continue reading “Convergence”
