Perhaps measuring animal intelligence by comparing it to human intelligence isn't the best litmus test.

<...> I’ve
never believed there is any animal more dangerous than a human being. I never will. It’s the intelligence. It’s the mind that makes it so.

Perhaps one of the most important things you can do for human beings is wean them off an animal-based diet. It hardens the arteries and runs up our health-care costs. The last thing a poor person can afford is a heart attack or cancer or a stroke. And that's all linked to a meat-based diet. I think animal liberation is human liberation.

It is impossible to underrate human intelligence - beginning with one's own.

I don't think there's anything unique about human intelligence.

We need to make a greater investment in human intelligence.
