“Anxiety and fear are emotions. Emotions exist only because they have given selective advantages. This makes it tempting to try to define different emotions in terms of their functions. Fear protects against present danger, anxiety against possible dangers. However, defining emotions in terms of their functions risks tacit creationism: the tendency to view bodies as if they are machines.”

“Therapists have long known that may depressions go away only after a person finally gives up some long-sought goal and turns his or her energies in another direction.”

“People are not controlled by some internal calculator that crudely motivates them to maximize their reproductive success. Instead, people form deep, lifelong emotional attachments and experience loves and hates that shape their lives. They have religious beliefs that guide their behavior, and they have idiosyncratic goals and ambitions. They have networks of friends and relatives.”

“...natural selection produces bodies and brains with assortments of adaptations shaped over thousands of generations to enhance reproductive success (fitness) but not necessarily well-being or happiness.”

“The scaling up of human social organization into mega-groups comprising millions (even hundreds of millions in modern nation states) would not have been possible without the human facility for culture acquisition and transmission on a massive scale.”

“The evolution of sexually selected traits can create particular kinds of vulnerabilities to mental disorders, which are often skewed in their sex ratios. Examples of mental disorders where sexual selection may play an important role include eating disorders, sexual dysfunction and schizophrenia.”

“The idea of mismatch is based on the fact that adaptations are shaped by selection within a given environment. If the environment changes rapidly and radically, some biological systems run the risk of becoming mismatched to the new environment. This is also referred to as -genome lag-.”

“Parental investment theory predicts that, on average, the sex that invests more in its offspring, including the size of gametes, gestation, lactation and child rearing, will be more selective when choosing a mate, and the less-investing sex will engage in more intra-sexual competition for access to mates.”

“This is not to say that I have outgrown those elemental desires that drew me to transhumanism—just that they express themselves in more conventional ways. Over the intervening years, I have given up alcohol, drugs, sugar, and bread. On any given week, my Google search history is a compendium of cleanse recipes, high-intensity workouts, and the glycemic index of various exotic fruits. I spend my evenings in the concrete and cavernous halls of a university athletic center, rowing across virtual rivers and cycling up virtual hills, guided by the voice of my virtual trainer, Jessica, who came with an app that I bought. It’s easy enough to justify these rituals of health optimization as more than mere vanity, especially when we’re so frequently told that physical health determines our mental and emotional well-being. But if I’m honest with myself, these pursuits have less to do with achieving a static state of well-being than with the thrill of possibility that lies at the root of all self-improvement: the delusion that you are climbing an endless ladder of upgrades and solutions. The fact that I am aware of this delusion has not weakened its power over me. Even as I understand the futility of the pursuit, I persist in an almost mystical belief that I can, through concerted effort, feel better each year than the last, as though the trajectory of my life led toward not the abyss but some pinnacle of total achievement and solution, at which point I will dissolve into pure energy. Still, maintaining this delusion requires a kind of willful vigilance that can be exhausting.”
