To me, trees are living beings and they have their own sort of personalities.

Surely it should be a matter of moral responsibility that we humans, different from other animals mainly by virtue of our more highly developed intellect and, with it, our greater capacity for understanding and compassion, ensure that medical progress slowly detaches its roots from the manure of non-human animal suffering and despair.

Certainly, if you look at human behavior around the world, you have to admit that we can be very aggressive.

You're thinking about putting scientists into small cages and doing research on them. I wish it could happen sometimes.

Certainly it's very often true that women tend to be a bit quieter and more prepared to sit there and let the animal tell you things.

We can learn to suppress our feelings for other reasons.

Without the heart to ground it and open it to who we really can be as human beings, the brain is a very dangerous machine. A machine that is saying: we've got to have economic growth; we've got to have unending economic growth, otherwise societies will collapse. And yet there should be something saying: wait a minute, this isn't going to work.
