Pigs have personality too. But most people would never know it given how livestock are treated.

Dogs have co-evolved with humans for tens of thousands of years, and demonstrate traits and behaviors that makes it much easier for humans to empathize and socialize with them. For example, you can tell when a dog is happy because their facial expressions resemble a human smile. Not so with livestock. Sure, you can figure it out after spending time with them, but it's inarguably not the same thing.

No, dogs don't smile. Some learn the baring of teeth as being peaceful instead of defensive, but most of them don't, or rather can't smile.

You can find the same exact "smile" in goats, sheep and pigs, they're definitely not making that face because they're happy.

Octopus has three acceptable pluralizations in English. Octopuses is correct by English rules. Octopodes is correct by strict etymological Greek-origin rules. Octopi is correct by English's pseudo-Latin cognate rules. The latter means that any singular noun ending in a consonant and "-us" can be pluralized by chopping off the "-us" and appending an "-i" or "-ii", like alumnus, hippopotamus, virus, bacillus, hummus, l…

Except there is no single authority of the English language (as seen in other language academies). As I mentioned in another comment, you may fall into a prescriptivist or descriptivist camp, but there's no authority to which one can appeal for a single answer. Generally speaking, octopuses is preferred by most if not all well known dictionaries in modern usage, and the pseudo-Latin cognate has fallen out of favor. I…

Neither the prescriptivists nor the descriptivists are correct.

There is, in fact, a way to assume greater authority over the English language than the power wielded by the median speaker. The person who can inject a memorable phrase into the popular culture--whether by writing a line that is read by many, or by speaking one that is heard by many--can steer the language closer to the path they may prefer.

For all our quibbling over technical correctness, if an author or scriptwriter decides to keep "octopi" alive, all they have to do is write it, with no explanation or justification necessary.

Stam that in your rassoodock and let it digimmer. It could make you frumious or mimsy, but you will grok who the lords of language are.

Great article on eating lobsters by the inimitable, late David Foster Wallace: http://www.gourmet.com/magazine/2000s/2004/08/consider_the_l...

Good lord, ten pages.

FWIW, the last 3 pages are footnotes.

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…

In her book "Animals make is human" - Temple Grandin makes the argument (among many others, this is not the main thesis of the book) that we can have a symbiotic relationship with animals, wherein we provide secure food supply, protection from predation and the associated stress, etc. and in return we eat the animal. Factory farming, by contrast has more in common with a parasitic relationship.

I think our ancestors called it hunting.

I bet there are other mammals you 'don't' eat - at least, that you'd refuse to eat. Man is the obvious one, but what about other primates, elephants, giraffes, etc.? I bet there are more animals that you don't eat than you do , and maybe there are even more that you would not be prepared to eat than you would .

Not really.. I would consider heating human. I have nothing against another mammal. However, I would require humane treatment of said human (or any animal or byproduct I eat). I'm not going to pretend I'm some morally superior being. But I'd like to at least reduce suffering of beings. After all, something else must die for me to eat (and I can't live on milk and honey).

This can't be serious

Fortunately for us, they have two biological strikes against developing that kind of culture. 1. They have short lifespans, limiting how much knowledge and wisdom an individual can acquire over its lifetime. 2. Reproduction is fatal. Males dies a few months after mating. Females spend all their time after the eggs are laid guarding them, and neglect to eat. They die of starvation around the time the eggs hatch. The o…

I also suspect it's a lot harder to advance technologically when you live underwater. One of the big boosts to human evolution was the mastery of fire and development of cooking.

Well, essentially cooking is trying to dissolve food in water - a non existing problem for octopi, mussels taste raw, too!

In what way is that a meaningful distinction?

It's a betrayal of trust. You know how Hitchhiker's Guide to the Galaxy has a pig that has been genetically bred to want to be eaten? Like that is it's greatest desire in the world. Dogs have been selectively bred over thousands of years to want to be our friends - to trust us, and to work together as companions. To deliberately kill and eat an animal like that is worse than eating any other.

You're conflating things at the species and individual level.

The dog species doesn't trust us (in any meaningful way). Individuals dogs do. Likewise, regardless of what we've bred "food" animals for, properly cared for farmed animal will hold the same implicit trust in a farmer as a dog does with his owner.

These evaluations need to be made at the individual level to make any sense.

Last time I was in Hawaii, I had the opportunity to interact with an octopus in the wild. I will never eat one again.

What happened? Was it afraid of you? I've never seen an octopus in the wild so I'm guessing it must be an experience. Would you mind sharing a bit more of what happened?

I had an experience in Hawaii while I was on a scuba tour.

In retrospective I kind of wish it hadn't happened but I appreciate that I have experience to share:

The PADI divemaster located one while we were scouting a reef and chased it out with knife then placed it on my hand. I disagree that the experience was forced upon the octopus now .. I respect them; they are very intelligent.

Anyway -- in my hand it expressed itself with touch. Initially tightening and posing itself in a drawn-back manner it spread on my hand and decided I was safe to explore. Our eyes met and my body relaxed. The octopus began to relax.

A tentacle wrapped around my wrist almost reassuringly. The octopus let me know I was not food. He / she seemed content to just hang out but I chose to let the encounter deescalate and put my hand near a rock then slowly unwound his / her tentacle.

The octopus seemed to understand my intent (my fear?) and glided over to the nearby rock to watch me go.
