Human beings are accustomed to think of intellect as the power of having and controlling ideas and of ability to learn as synonymous with ability to have ideas. But learning by having ideas is really one of the rare and isolated events in nature.

Human folk are as a matter of fact eager to find intelligence in animals.

From the lowest animals of which we can affirm intelligence up to man this type of intellect is found.

Dogs get lost hundreds of times and no one ever notices it or sends an account of it to a scientific magazine.

The discovery of heroes is rarely linear or obvious. They usually sneak up on you.

We have a lot of suspicion of robots in the West. But if you look cross-culturally, that isn't true. In Japan, in their science fiction, robots are seen as good. They have Astro Boy, this character they've fallen in love with and he's fundamentally good, always there to help people.
