I will argue that every scrap of biological diversity is priceless, to be learned and cherished, and never to be surrendered without a struggle.

Even as empiricism is winning the mind, transcendentalism continues to win the heart.

We don't need to clear the 4 to 6 percent of the Earth's surface remaining in tropical rain forests, with most of the animal and plant species living there.

America in particular imposes an horrendous burden on the world. We have this wonderful standard of living but it comes at enormous cost.

Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.

Every kid has a bug period, I like to say, and I just got so fascinated and I had that experience, that wonderful life of being able to go out on my own without really any supervision at all. I just lucked out that way. I was trusted as a kid.

Secular humanists can sit around and talk about their love of humanity, but it doesn't stack up against a two-millennium-old funeral high mass.
