Certainly! Here are 10 impactful quotes from Robert Sapolsky's Behave: The Biology of Humans at Our Best and Worst:
🧠 1. On the Complexity of Human Behavior
“You don’t have to choose between being scientific and being compassionate.”
— Robert M. Sapolsky(Goodreads)
This quote emphasizes the importance of integrating scientific understanding with empathy when examining human behavior.
🧬 2. On the Role of the Amygdala
“In other words, the default state is to trust, and what the amygdala does is learn vigilance and distrust.”
— Robert M. Sapolsky(Goodreads)
Sapolsky highlights the brain's natural inclination towards trust and how the amygdala can modify this tendency in response to experiences. (bookquoters.com)
⚖️ 3. On Moral Judgments
“Morality is simply the attitude we adopt towards people whom we personally dislike.”
— Robert M. Sapolsky(Goodreads)
This statement reflects on how personal biases can shape our moral perspectives.
🧪 4. On the Impact of Stress
“Sustained stress has numerous adverse effects. The amygdala becomes overactive and more coupled to pathways of habitual behavior; it is easier to learn fear and harder to unlearn it.”
— Robert M. Sapolsky(Goodreads)
Sapolsky discusses how chronic stress can alter brain function, making it more challenging to overcome fear.
🧠 5. On Adolescent Brain Development
“First, no part of the adult brain is more shaped by adolescence than the frontal cortex. Second, nothing about adolescence can be understood outside the context of delayed frontocortical maturation.”
— Robert M. Sapolsky(Roxanna Elden)
This quote underscores the significant impact of adolescence on brain development, particularly the frontal cortex. (Roxanna Elden)
🧬 6. On Testosterone and Aggression
“Testosterone makes us more willing to do what it takes to attain and maintain status. And the key point is what it takes.”
— Robert M. Sapolsky(Reddit)
Sapolsky explores how testosterone influences behavior, particularly in the context of status and aggression. (Reddit)
🧠 7. On the Biology of Empathy
“Someone does something lousy and selfish to you in a game, and the extent of insular and amygdaloid activation predicts how much outrage you feel and how much revenge you take.”
— Robert M. Sapolsky(bookquoters.com)
This statement links brain activity to emotional responses like outrage and the desire for revenge.
🧬 8. On the Influence of Environment
“How’s this for fascinating: Heritability of various aspects of cognitive development is very high (e.g., around 70 percent for IQ) in kids from high–socioeconomic status (SES) families but is only around 10 percent in low-SES kids.”
— Robert M. Sapolsky(Goodreads)
Sapolsky highlights how environmental factors can significantly influence cognitive development. (bookquoters.com)
🧠 9. On the Role of Oxytocin
“Oxytocin, the luv hormone, makes us more prosocial to Us and worse to everyone else.”
— Robert M. Sapolsky(Goodreads)
This quote discusses the dual nature of oxytocin, promoting in-group bonding while potentially fostering out-group hostility.
⚖️ 10. On the Nature of Morality
“Things that seem morally obvious and intuitive now weren’t necessarily so in the past; many started with nonconforming reasoning.”
— Robert M. Sapolsky(Goodreads)
Sapolsky reflects on how moral standards evolve over time, often beginning with unconventional ideas.
