There are good mothers and bad ones, but most of them are somewhere in-between.

A good mother is protective but not over-protective. She's patient, she's affectionate, she's playful, but above all she is supportive.

Chimpanzees have given me so much. The long hours spent with them in the forest have enriched my life beyond measure. What I have learned from them has shaped my understanding of human behavior, of our place in nature.

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.

We can learn to suppress our feelings for other reasons.

Empathy is really important.. Only when our clever brain and our human heart work together in harmony can we achieve our full potential.

Surely it should be a matter of moral responsibility that we humans, different from other animals mainly by virtue of our more highly developed intellect and, with it, our greater capacity for understanding and compassion, ensure that medical progress slowly detaches its roots from the manure of non-human animal suffering and despair.
