Octopuses have hundreds of suckers, each one equipped with its own ganglion with thousands of neurons. These 'mini-brains' are interconnected, making for a widely distributed nervous system. That is why a severed octopus arm may crawl on its own and even pick up food.

If you look at national economies today, for example, the American economy, the European economy, the Indians, the Chinese, we're all tied together. If one of them sinks, the rest are going to sink with them and if one floats, the rest are lifted up. I find that very interesting.

Dogmatists have one advantage: they are poor listeners.

The evolutionary struggle for survival is really a self-serving series of blows and stabs, and yet it can lead to extremely social animals like dolphins, wolves or, for that matter, primates.

Armies are a purely human invention. Most soldiers who go to war nowadays don't even do it because they're inherently aggressive.

Science is not inherently good.

We would much rather blame nature for what we don't like in ourselves than credit it for what we do like.
