Yesterday, the president compared his approval rating to the approval ratings of two government experts, Dr. Anthony Fauci and Dr. Deborah Birx. The moment was captured in the “What a Day” newsletter published by Crooked Media:
We have more than 150,000 dead, millions have lost their jobs and we are pitied or mocked by the rest of the world, yet Donald isn’t popular. Life can be so unfair.
Peter Godfrey-Smith is an Australian professor of philosophy who has spent many hours scuba-diving in order to observe the behavior of octopuses and cuttlefish. The book is an attempt to trace the evolution of mental activity from its earliest beginnings hundreds of millions of years ago, when bacteria began reacting to their surroundings. The author believes that mind and consciousness didn’t suddenly spring into existence; they developed gradually through millions of years. But he admits that nobody knows for sure.
Neither do we know what it’s like to be an octopus. We don’t even know for certain that it’s like anything at all. Maybe octopuses go about their business without feelings or anything like consciousness. Godfrey-Smith, however, argues that it’s reasonable to believe that creatures of many sorts feel pain when they are injured. But where to draw the lines (if there are any lines) between bacteria that simply react, animals that feel pain and creatures like us who are self-conscious is a mystery.
Octopuses are especially interesting because our common ancestors lived about 500 million years ago. Octopuses developed complex nervous systems, arranged differently than ours, independently from most other animals, including us. That means, in Godfrey-Smith’s words, “meeting an octopus is, in many ways, the closest we’re likely to get to meeting an intelligent alien”. It’s really too bad that they can’t tell us what it’s like to be them.
I wish the book ended with a summation of the author’s conclusions. I do remember the idea that nervous systems first evolved in order to respond to a living thing’s surroundings, and then to monitor its internal states and control its movements. And I remember a lot about the interesting behavior of octopuses and their close relations, cuttlefish. But I can’t say I came to any solid conclusions about the deep origins of consciousness. If the author reached any conclusions, he should have reminded his readers what they were.
