"The less it is possible that something can be,
the more it must be."

I've been sitting on this unbelievably gripping, humorous, and intellectually stimulating lecture by Robert Sapolsky for months now. I'm not sure why. My work life whisked me away, but, in watching this video again, it's too good not to share.

Sapolsky is one of the world's leading neuroscientists who explores "the biology of neurons" and how stress factors in to our social lives. He's an incredible storyteller who makes sense of the human species by studying primates, particularly baboons. Using many examples from the wild, he debunks a series of commonly held assumptions that most people believe define human beings as being distinct, as being unique to our species: theory of mind, the Golden Rule, empathy, tit-for-tat, etc.

Despite all the universal behaviors we humans hold in common with other animals, Sapolsky says that humans have one trait that best defines and distinguishes us from other species: the ability to hold two contradictory ideas in our head, and yet continue on in the face of it.

Dr. Robert M. Sapolsky Speaks at StanfordDuring a staff meeting several months ago, I recommended that one of our associate producers do some research on Dr. Sapolsky as a potential interview with Krista. The feedback: Dr. Sapolsky was a good storyteller with great depth of experience, but there was concern that his atheism might be too strident and might not work for our program.

To me, it’s these types of voices that we want to include in our repertoire of shows. He's a non-believer who embraces the paradox himself. He's not just against religion or worshiping a deity. He lives an intellectual life that listens to these religious and philosophical voices and internalizes them. He takes them seriously and doesn't dismiss them.

So, when I'm evaluating future guests, I'm looking for clues, for indicators that strike me as openness to ideas without personally accepting them as doctrine. So, even though Dr. Sapolsky declares himself strident in the lecture above, he makes a Niebuhrian statement like the one that heads the top of this page. And, shortly thereafter, posts a slide with a quotation from Danish philosopher and theologian Søren Kierkegaard:

"Christian faith requires that faith persists in the face of the impossible, and that humans have the capacity to simultaneously believe in two contradictory things."

Sister Helen PrejeanAnd then he immediately cites the mercy-filled work of Sr. Helen Prejean, a Roman Catholic nun, and quotes her:

"The less forgivable the act, the more it must be forgiven. The less loveble the person is, the more you must find the means to love them."

What's even more delightful is Sapolsky's own ability and intellectual curiosity to live comfortably and reconcile his own positions and beliefs. He marvels:

"As a strident atheist, this strikes me as the most irrational, magnificent thing we are capable of as a species. … And this one does not come easily. On a certain level, the harder this is, this contradiction, to take the impossibility of something and to be the very proof that it must be possible and must become a moral imperative, the harder it is to do that, the more important it is."

Sapolsky is a wonderful storyteller and enormously insightful. I do hope Krista interviews him. I do not consider him strident just confident (comfortable) in his beliefs.

Robert Sapolsky would be a brilliant guest. I encourage you to re-engage the people who sense his atheism might be too strident. The change to Being should open up options like this a little. Some atheists are extraordinarily important to our understanding of faith. The best of the atheists will allow the faith of religious and spiritual folks to flourish with new ideas.

Although this is a interesting and more-or-less unusual idea as to what "makes us human" it unfortunately turns a blind eye to those with significant mental disabilities and ultimately helps to perpetuate the stereotype that such persons are not fully human.

Moreover, although it is alluring to try to propose "Quality X" as being the definitive characteristic which makes us human, I shudder each time some brilliant person wants to suggest that a mental capacity is what separates humans from other animals.

Now, maybe there is such a thing as "Quality X" that distinguishes us as humans apart from other animals, but lets make sure it is one that really speaks for ALL humans - not just ones with university degrees.

Lastly, with a number of your programs touching on or directly focusing upon those with mental disabilities, I'm baffled as to why you wouldn't pick up on this in your post, Trent, and note this as a problem with Sapolsky's notion.

In the end, if we accept Sapolsky's idea we are just finding another (apparently) sophisticated way to keep those with significant mental disabilities in the "sub-human" category – which seems not the least bit enlightened or humane. Maybe you folks need to go re-listen to your own episode with Jean Vanier or read some of Stanley Hauerwas' writings.

All good wishes,

What a wonderful and poignant speech given by this amazing man. I will be looking forward to hearing more from him on your show. Thanks for sharing this.

Most definitely, have the Doctor on. I value your show as a forum where ideas and beliefs are welcome and where exclusivity is unpopular. I value his recognition of our paradoxical nature within his beliefs. You have my vote!
