I used to very politely say that if there is free will then it's in all sorts of boring places, like whether you're going to pick up this or that fork as you begin your meal. There really is none: It's all biology.

The stress response is incredibly ancient evolutionarily. Fish, birds and reptiles secrete the same stress hormones we do, yet their metabolism doesn't get messed up the way it does in people and other primates.
Interpretation
What this quote means
The stress response is a primitive survival mechanism shared among various species without the negative metabolic consequences seen in humans.
Robert Sapolsky highlights the evolutionary origins of the stress response, indicating that it is a fundamental survival mechanism that exists across many species, including fish, birds, and reptiles. Unlike humans and other primates, these animals do not exhibit the same detrimental effects on metabolism from stress, suggesting a difference in how stress impacts different organisms, reflecting both the adaptability of life and the specific vulnerabilities of human physiology.

My adolescent rebellions took the form of, if anything, passive aggressively doing what was asked of me but doing it ten times more than what was asked of me, so that eventually they'd have to beg me to stop.

When humans invented material inequality, they came up with a way of subjugating the low-ranking like nothing ever seen before in the primate world.

Yes, genes are important for understanding our behavior. Incredibly important - after all, they code for every protein pertinent to brain function, endocrinology, etc., etc. But the regulation of genes is often more interesting than the genes themselves, and it's the environment that regulates genes.

I expected social rank to be the determining factor in health, and in some ways that's true. But far more important is what sort of society that rank occurs in. Being low ranking in a benevolent troop is a hell of a lot better for your blood pressure than being low ranking in an aggressive troop.

The investigation of nature is an infinite pasture-ground where all may graze, and where the more bite, the longer the grass grows, the sweeter is its flavor, and the more it nourishes.

We look for medicine to be an orderly field of knowledge and procedure. But it is not. It is an imperfect science, an enterprise of constantly changing knowledge, uncertain information, fallible individuals, and at the same time lives on the line. There is science in what we do, yes, but also habit, intuition, and sometimes plain old guessing. The gap between what we know and what we aim for persists. And this gap complicates everything we do.

Spacewalking trumps everything. Viscerally, it is a phenomenal place to be; to be able to glance right and see the world, glance left and see the universe, and realise for a moment that you're holding on to your known existence with one hand. That's the thing.

Well, biology today as I see it has an amiable look - quite different from the 19th-century view that the whole arrangement of nature is hostile, 'red in tooth and claw.' That came about because people misread Darwin's 'survival of the fittest.'

Listen, I mean that from my knowledge of the world that I see around me, I think that it is much more likely that the reports of flying saucers are the results of the known irrational characteristics of terrestrial intelligence than of the unknown rational efforts of extra-terrestrial intelligence.

You have ... been told that science grows like an organism. You have been told that, if we today see further than our predecessors, it is only because we stand on their shoulders. But this [Nobel Prize Presentation] is an occasion on which I should prefer to remember, not the giants upon whose shoulders we stood, but the friends with whom we stood arm in arm ... colleagues in so much of my work.
