I suppose what's happened recently has confirmed suspicions I voiced in the book, and I think made clearer some of those things that I point out. For instance I have a section of the book where I talk about the possibility of torture.

The most callous, stupid things were done just because regulations required them...It was not until 1983, for example, that U.S. federal agencies stated that substances known to be caustic irritants such as lye, ammonia, and oven cleaners, did not need to be tested on the eyes of conscious rabbits.

If it is in our power to prevent something bad from happening, without thereby sacrificing anything of comparable moral importance, we ought, morally, to do it.

To give preference to the life of a being simply because that being is a member of our species would put us in the same position as racists who give preference to those who are members of their race.

If you have the abilities to earn a lot of money and if you have the character to persist in giving that to the most effective charities you can find, then that may be the best thing that you can do. And - also, if you do become a Wall Street banker, I think you need to be aware of what you're doing in terms of your daily work, not just earning money to give a lot away. But you need to think about - am I harming people through the work that I'm doing?

All the arguments to prove man's superiority cannot shatter this hard fact: in suffering, the animals are our equals.
