I believe that the best way to create good living conditions for any animal, whether it's a captive animal living in a zoo, a farm animal or a pet, is to base animal welfare programs on the core emotion systems in the brain. My theory is that the environment animals live in should activate their positive emotions as much as possible, and not activate their negative emotions any more than necessary. If we get the animal's emotions rights, we will have fewer problem behaviors... All animals and people have the same core emotion systems in the brain.

When I was younger I was looking for this magic meaning of life. It's very simple now. Making the lives of others better, doing something of lasting value. That's the meaning of life, it's that simple.

I feel very strongly, we've got to give animals a good life. I've worked really hard improving slaughter plants and animal handling and transport. And people have said to me, why don't you work on improving conditions on pig farms? And basically, to be effective on making real change out there on the ground, you can only work on so many things. You know, you get too distributed, you're not effective.

These diagnostic profiles like depression, ADHD, autism, dyslexia, it's half science and the other half is a committee of doctors bickering over what it should be, and it has changed. It's not precise like a diagnosis of tuberculosis would be very precise.

Normal people have an incredible lack of empathy. They have good emotional empathy, but they don't have much empathy for the autistic kid who is screaming at the baseball game because he can't stand the sensory overload. Or the autistic kid having a meltdown in the school cafeteria because there's too much stimulation.

Everything I think is in pictures.

If I could snap my fingers and be nonautistic, I would not. Autism is part of what I am.
