I think the best evenings are when we have messages, things that make us think, but we can also laugh and enjoy each other's company.

It made me feel particularly sickened to know that this kind of callous attitude toward animals is repeated again and again in laboratories around this country.

It's not a pretty picture, but there are reasons for hope.

Be assured that our individual actions, collectively, make a huge difference.

It was both fascinating and appalling to learn that chimpanzees were capable of hostile and territorial behavior that was not unlike certain forms of primitive human warfare.

It is these undeniable qualities of human love and compassion and self-sacrifice that give me hope for the future. We are, indeed, often cruel and evil. Nobody can deny this. We gang up on each one another, we torture each other, with words as well as deeds, we fight, we kill. But we are also capable of the most noble, generous, and heroic behavior.

If we start with chimpanzees, they differ from us with the composition of the DNA by only just over one percent. So, as far as genetics go, we're almost identical. The composition of the blood, the immune system, the structure of the brain - almost identical.
