There are times when one cannot accept facts for fear of shattering one's being. As I listened to Ian's news, all of Digit's life, since my first meeting with him as a playful little ball of black fluff ten years earlier, passed through my mind. From that moment on, I came to live within an insulated part of myself.

When you realize the value of all life, you dwell less on what is past and concentrate more on the preservation of the future.

I have no friends. The more you learn about the dignity of the gorilla, the more you want to avoid people.

[About gorillas] You take these fine, regal animals. How many (human) fathers have the same sense of paternity? How many human mothers are more caring? The family structure is unbelievably strong.

Active conservation [of gorillas] involves simply going out into the forest, on foot, day after day after day, attempting to capture poachers, killing-regretfully-poacher dogs, which spread rabies within the park, and cutting down traps.

None of the three great apes is considered ancestral to modern man, Homo sapiens, but they remain the only other type of extant primate with which human beings share such close physical characteristics. From them we may learn much concerning the behavior of our earliest primate prototypes, because behavior, unlike bones, teeth, or tools, does not fossilize.
