The initial animosity between divergent approaches can be overcome if we realize that each has something to offer that the other lacks. We may weave them together into a new whole that is stronger than the sum of its parts.

If we look straight and deep into a chimpanzee's eyes, an intelligent self-assured personality looks back at us. If they are animals, what must we be?

Along with people in other creative professions, such as artists and musicians, many scientists experience this transcendence. I do so every day. For one, it's impossible to look an ape in the eye and not see oneself. There are other animals with frontally oriented eyes, but none that give you the shock of recognitions of the ape's. Looking back at you is not so much an animal but a personality as solid and willful as yourself.

Even the staunchest atheist growing up in Western society cannot avoid having absorbed the basic tenets of Christian morality. Our societies are steeped in it: everything we have accomplished over the centuries, even science, developed either hand in hand with or in opposition to religion, but never separately. It is impossible to know what morality would look like without religion. It would require a visit to a human culture that is not now and never was religious. That such cultures do not exist should give us pause.

It is said that man is wolf to man. I find this very unfair to wolves.

The book of nature is like the Bible: Everyone reads into it what they want, from tolerance to intolerance, and from altruism to greed. It’s good to realize, though, that if biologists never stop talking of competition, this doesn’t mean they advocate it, and if they call genes selfish, this doesn’t mean that genes actually are. Genes can’t be any more “selfish” than a river can be “angry,” or sun rays “loving.” Genes are little chunks of DNA. At most, they are “self-promoting,” because successful genes help their carriers spread more copies of themselves.

I sometimes try to imagine what would have happened if we'd known the bonobo first and the chimpanzee only later or not at all. The discussion about human evolution might not revolve as much around violence, warfare, and male dominance, but rather around sexuality, empathy, caring, and co-operation. What a different intellectual landscape we would occupy!”,Our Inner Ape

We have a tendency to describe the human condition in lofty terms, such as a quest for freedom or striving for a virtuous life, but the life sciences hold a more mundane view: It’s all about security, social companionships, and a full belly. There is obvious tension between both views, which recalls that famous dinner conversation between a Russian literary critic and the writer Ivan Turgenev: 'We haven’t yet solved the problem of God,' the critic yelled, 'and you want to eat!

Having escaped the Dark Ages in which animals were mere stimulus-response machines, we are free to contemplate their mental lives. It is a great leap forward, the one that Griffin fought for. But now that animal cognition is an increasingly popular topic, we are still facing the mindset that animal cognition can be only a poor substitute of what we humans have. It can’t be truly deep and amazing. Toward the end of a long career, many a scholar cannot resist shining a light on human talents by listing all the things we are capable of and animals not. From the human perspective, these conjectures may make a satisfactory read, but for anyone interested, as I am, in the full spectrum of cognitions on our planet, they come across as a colossal waste of time. What a bizarre animal we are that the only question we can ask in relation to our place in nature is “Mirror, mirror on the wall, who is the smartest of them all?

I sometimes try to imagine what would have happened if we’d known the bonobo first and the chimpanzee only later—or not at all. The discussion about human evolution might not revolve as much around violence, warfare and male dominance, but rather around sexuality, empathy, caring and cooperation. What a different intellectual landscape we would occupy!

If faith makes people buy an entire package of myths and values without asking too many questions, scientists are only slightly better.

[T]he term 'nonhuman' grates on me, since it lumps millions of species together by an absence, as if they were missing something. Poor things, they are nonhuman! When students embrace this jargon in their writing, I cannot resist sarcastic corrections in the margin saying that for completeness's sake, they should add that the animals they are talking about are also nonpenguin, nonhyena, and a whole lot more.

Our societies probably work best if they mimic as closely as possible the small-scale communities of our ancestors. We certainly did not evolve to live in cities with millions of people where we bump into strangers everyone we go, are threatened by them in dark streets, sit next to them in the bus, and give them the finger in traffic jams.

Ironically, torture requires empathy, too, in the sense that one cannot deliberately inflict pain without realizing what is painful.

Friedrich Nietzsche, who famously gave us the ‘God is dead’ phrase was interested in the sources of morality. He warned that the emergence of something (whether an organ, a legal institution, or a religious ritual) is never to be confused with its acquired purpose: ‘Anything in existence, having somehow come about, is continually interpreted anew, requisitioned anew, transformed and redirected to a new purpose.’ This is a liberating thought, which teaches us to never hold the history of something against its possible applications. Even if computers started out as calculators, that doesn’t prevent us from playing games on them. (47) (quoting Nietzsche, the Genealogy of Morals)

Without agreement on rank and a certain respect for authority there can be no great sensitivity to social rules, as anyone who has tried to teach simple house rules to a cat will agree.
