Algae can also survive in conditions human couldn't. That isn't a very meaningful bar for intelligence.

Single celled organisms are in control, they're the original intelligence. Our minds are just slaves to supercolonies of trillions of cells.

Way to make me feel worse about eating them.

Apart from cognitive skills, an important factor is the capacity of suffering. So even dumb animals might be able to feel intense pain. In humans, while forms of suffering like loneliness, depression can be bad, pure physical pain can itself a terrible thing. For instance severe torture for 10 minutes can be worse than months of depression. Now even if cognitive aspects are diminished in animals, the physical senses…

Cephalopods are the only invertebrates that are banned from certain types of research because of this.

I love how completely alien they are compared to us. The sort of decentralized nature of their nervous system compared to our path of evolution. (I'm no marine/evolutionary biologist so I'm probably butchering the terminology...) I loved reading the two pieces Sy Montgomery wrote that are in Orion Magazine. https://orionmagazine.org/article/deep-intellect/ And the follow-up: https://orionmagazine.org/2011/11/intervie…

Those are shorter forms of pieces in her long-form book:

Quick read, and also recommended for more good octopus anecdotes that inform this question.

> And yet . . . could we be missing something here? While they can’t see much of their own kaleidoscopic skins, they can clearly sense inside what they are doing.

I agree it's a little silly. But I think it might be more charitably described as "speculation that remains intriguing to ponder, even though it has no evidentiary support." And the reason they inject it is, of course, that certain readers are more interested in thinking about that kind of stuff than hard scientific evidence.

If you really think this is just "spasmodic blather," then I think you may be missing a lot of important things about the human experience--and even, I'd submit, some of the true wonder of science. (This is not to say, however, that you must find it interesting, much less persuasive. I don't.)

Isn't Godfrey-Smith's belief in fact also "just a byproduct of neural activity"?

Well pigs are smarter than dogs, and many people eat them.

Yeah, but a dog's got personality. Personality goes a long way.

Having dealt with both I would rate pigs higher in personality than dogs. They are very smart, learn stuff quickly and definitely have individual personalities.

I always find it very hypocritical that the same people who have no problem eating pork are outraged over people eating dogs in Asia.

If you like reading about minds that are fundamentally different from our own, you might also enjoy the science fiction novel "Blindsight" by Peter Watts. Exploring the space of possible minds in the universe is a fundamental theme of that work.
