Hidden Logic of Genes In Genesis?
Scarcely noticed in the Eden story, there lurk fruitful scientific ideas about why biology generated morality.
1. Scientist Loren Eiseley saw fruitful science in Genesis (in the exile, not the creation): “The story of Eden is a greater allegory than man has ever guessed.” It can be read as being about biology begetting morality.
2. Eiseley described how through natural selection, “good and evil would enter and possess the world.” He grasped how evolution generated non-genetic ethics.
3. Eiseley contrasted instinctive life versus social-learning-structured life. The former needs no meaningful morality, the later uses the logic of forbidden fruit (of “The Tree of Knowledge of Good and Evil”).
4. Updating Eiseley’s case, the “world of instinct” is entirely genetically programmed. All traits have fixed genetic scripts, changing only slowly, intergenerationally (phenotypes = subsets of genotypes).
5. But social non-genetic inheritances radically changed the game; in uniquely human ways behavioral and cognitive traits weren’t as genetically determined (phenotypes wider than genotypes, see praxotype + cognotype).
6. Eiseley notes our social transmission-based life strategies need unique adaptive changes (e.g., postnatal brain size trebling, much longer immaturity, persisting parental bonds).
8. It’s obvious how tools are adaptive, but languages and cooperation rules are non-material social tools.
10. That’s the missing link to nature’s moralities—no humanlike creature thrives without received knowledge and rules about “good and bad” choices. The “sapiens” in homo sapiens means wisdom, i.e. choosing well (from Latin for taste, judgement). Our key trick is acquiring the wisdom of others.
12. So all humans face Eve’s dilemma—born with behavioral freedom and curiosity into risky environments, with socially punishable received rules. Rousseau’s we’re “born free” but everywhere in chains is the human condition incarnate (with inalienable social chains, see “relational rationality”).
13. Harold Bloom notes that the earliest Genesis texts depict humans as theomorphic (“god-shaped,” in god’s image as moral choosers and creators). Leon Kass agrees, deeming Eden’s exile a rise, not a fall.
17. Eiseley saw unnaturally selective thinking about evolution as mirroring elite Victorian biases. Dawkins later amplified the same adamantly competition-centric view, but we’re on the eve of grasping how much of life features cooperation (every I is a we, Ed Yong).
18. Darwin called unmoral humans “unnatural monsters,” and out of Eden came not only “endless forms most beautiful” but also endless strategies intertwining competition and cooperation.

Harvard psychologists discover why we dislike the people who deliver bad news.
- A new study looked at why people tend to "shoot the messenger".
- It's a fact that people don't like those who deliver them bad news.
- The effect stems from our inherent need to make sense of bad or unpredictable situations.
He reminds us that meaning is wherever we choose to look.
- Alan Watts suggests there is no ultimate meaning of life, but that "the quality of our state of mind" defines meaning for us.
- This is in contradiction to the notion that an inner essence is waiting to be discovered.
- Paying attention to everyday, mundane objects can become highly significant, filling life with meaning.
If life exists on Mars, there's a good chance it's related to us, say researchers.
When MIT research scientist Christopher Carr visited a green sand beach in Hawaii at the age of 9, he probably didn't think that he'd use the little olivine crystals beneath his feet to one day search for extraterrestrial life.
