The principal activities of brains are making changes in themselves.

But the big feature of human-level intelligence is not what it does when it is works but what it does when it's stuck.

There are three basic approaches to AI: Case-based, rule-based, and connectionist reasoning.

We rarely recognize how wonderful it is that a person can traverse an entire lifetime without making a single really serious mistake — like putting a fork in one's eye or using a window instead of a door.

In general, we’re least aware of what our minds do best.

Everything, including that which happens in our brains, depends on these and only on these: A set of fixed, deterministic laws.

The secret of what anything means to us depends on how we've connected it to all the other things we know. That's why it's almost always wrong to seek the "real meaning" of anything. A thing with just one meaning has scarcely any meaning at all.
