What you do makes a difference, and you have to decide what... - Jane Goodall

"A sense of calm came over me. More and more often I found myself thinking, "This is where I belong. This is what I came into this world to do."

"In what terms should we think of these beings, nonhuman yet possessing so very many human-like characteristics? How should we treat them? Surely we should treat them with the same consideration and kindness as we show to other humans; and as we recognize human rights, so too should we recognize the rights of the great apes? Yes."

"I think the most important thing is to keep active and to hope that your mind stays active."

"But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees."

"The greatest danger to our future is apathy."
