The more we learn, the more questions arise.

I sense that, without sensitivity to physical pain and pleasure, man would not have known self-interest, and consequently know just or unjust acts. Thus, physical sensitivity and self-interest are the authors of all justice.

From my earliest memories I was fascinated by animals. I would explore my backyard for insects and gaze at anthills until my elbows became sore. When I was 8, my mother bought me a book of North American birds and I've been keen on birdwatching since.

The more we learn, the more questions arise.

Humankind won't find peace as long as we're treating feeling animals as if they were so many blocks of wood.

People don't like change when it comes to changing their own lifestyle habits.

They (animals) are not just living things; they are beings with lives... that makes all the difference in the world...next time you are outside...notice the first bird you see…you are beholding a unique individual with personality traits, an emotional profile, and a library of knowledge built on experience…what you are witnessing is not just biology, but a biography.
