Astronaut vs. Cowboy Ethics
Comparing “astronaut” to “cowboy” ethics can show that Locke's limits on liberty need to be revised. We once could see that pitting self-interest against collective self-preservation wasn’t rational. Me-opic and logically unworkable ideas that economics sometimes encourage have made that harder to see.
“Freedom in a commons brings ruin to all.” So says Garrett Hardin reassessing his misnamed “tragedy of the commons” parable. He’s right, and since certain kinds of “commons” are unavoidable, his logic means we are too free. Revised logical limits of liberty are needed.
1. Hardin’s scenario described incentives for herders to overgraze a commons (public pasture). Pursuing their narrow self-only-interest, they ruin the shared resource. Hardin later said his “weightiest mistake” was not noting that the fault lies in the “unmanaged” freedom.
2. Humans are the freest, least genetically constrained species (see praxotype). But rule-free freedom produces unproductive chaos. Our linguistic and ethical rule-processors evolved to coordinate and constrain our freedoms, productively.
3. The Golden Rule — “Do unto others as you would have them do unto you” — easily cures Hardin’s “tragedy.” But somehow its symmetric logic is losing sway.
4. Locke defined commonly accepted limits on liberty in 1690: “Reason ... teaches all Mankind ... no one ought to harm another in his Life, Health, Liberty, or Possessions.” But by 1968, Hardin believed self-maximization was “rational,” even when collectively ruinous.
5. We know we are not free to harm any other person’s interests. So why would harming the interests of all others (the commons) be OK? “The commons” are commoner than many believe (e.g., our unfence-able microbial commons; markets are commons-like resources).
6. Unlike the Golden Rule or Locke’s limits, Hardin’s herder logic is too me-opic and asymmetric. It “works” only if others don’t do it. It might make twisted short-term sense, but it can’t last. Contagious behaviors bind our common fate to what we allow ourselves, and others to do.
7. Tragedy once was more than a bad ending. It meant being at the mercy of a situation where it was impossible to avoid disaster. Hardin’s hard-of-thinking herders hardly fit the bill. Just don’t overgraze — and organize to ensure no one else does. A trivially solvable “tragedy” isn’t worthy of the name.
8. Avoiding foreseeable doom is rational. Pitting self-interest against collective self-preservation isn’t. We once could see this. Economic cowboy ethics risks ignoring it.
9. Hardin called economics “a minor specialty” within ecology, and compared “cowboy” to “spaceship” ethics. Ecology uses spaceship-ethics: Everything is limited and valuable. Economics often encourages cowboy ethics; huge, free herds suggest it’s OK to shoot buffalo just to eat the tongue = near-extinction. Economics and ethics must now work better.
10. Locke’s liberty limits must be redrawn. Rule systems that permit — or promote — damaging what their followers depend on, don’t survive. Greed easily becomes systemically tragic (e.g., Prisoners Dilemmas).
11. We need to better grasp our own needs. And that others, and their needs, are inescapable.
“Reason teaches ... all ... who will but consult it.”
12. Know your needs. Don’t damage what supplies them. Don’t let others either. Or you’re doomed.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
- In some fundamental ways, humans haven't changed all that much since the days when we were sitting around communal fires, telling tales.
- Although we don't always recognize them as such, stories, symbols, and rituals still have tremendous, primal power to move us and shape our lives.
- This is no less true in the workplace than it is in our personal lives.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
- The word "creative" is sometimes waved around like a badge of honor. We speak of creativity in hushed tones, as the special province of the "talented". In reality, the creative process is messy, open, and vulnerable.
- For this reason, creativity is often at its best in a group setting like brainstorming. But in order to work, the group creative process needs to be led by someone who understands it.
- This sense of deep trust—that no idea is too silly, that every creative impulse is worth voicing and considering—is essential to producing great work.
