One great mystery is why sexual reproduction became dominant for higher life-forms. Optimization theory says it should be otherwise.
Take a fish or lizard, ideally suited to her environment, with just the right internal chemistry, agility, camouflage—whatever it takes to be healthy, fecund, and successful in her world. Despite all this, she cannot pass on her perfect characteristics. After sex, her offspring will be jumbles, getting only half of their program from her and half their re-sorted genes somewhere else.
Sex inevitably ruins perfection. Parthenogenesis would seem to work better—at least theoretically. In simple, static environments, well-adapted lizards who produce duplicate daughters are known to have advantages over those using sex.
Yet, few complex animals are known to perform self-cloning. And those species exist in ancient, stable deserts, always in close company with a related sexual species.
Sex has flourished because environments are seldom static. Climate, competition, parasites—all make for shifting conditions. What was ideal in one generation may be fatal the next. With variability, your offspring get a fighting chance. Even in desperate times, one or more of them may have what it takes to meet new challenges and thrive.
Each style has its advantages, then. Cloning offers stability and preservation of excellence. Sex gives adaptability to changing times. In nature it is usually one or the other. Only lowly creatures such as aphids have the option of switching back and forth.

If there are still honest-smart men and women within those old and noble traditions, they should think carefully, observe and diagnose the illness. They should face the contradiction. Discuss the conflation. And then do as Warren Buffett and Bill Gates and many others have done. Choose the miracle of creative competition over an idolatry of cash.

They should stand up..

He managed to lie by implication while speaking words that were the literal truth, a skill he had grown good at, if not proud of.

How might our world be different, if our literature, to say nothing of our politics, behaved more like a rational, intrepid adult than a hand-wringing adolescent?

Every marvel of our age arose out of the critical give and take of an open society. No other civilization ever managed to incorporate this crucial innovation, weaving it into daily life. And if you disagree with this ... say so!

“Where there is mind, there is always solution,” Keneenk taught. All problems contained the elements of their answer.

nous pouvons nous doter de garanties constitutionnelles, établir une stricte répartition des pouvoirs, mais de telles mesures ne prennent un sens que lorsque les citoyens assurent que ces garde-fous soient respectés. Or, ceux qui ont soif de puissance et d’argent sont sans cesse à l’affût d’un moyen de violer les lois ou de les tourner à leur avantage.

Apparently, the Fates were not so unsubtle as to deal him another blow just yet. He knew they didn’t operate that way. They always let you hope for a while longer, then strung it out before they really let you have it.

Where it is strongest, it must still contend ceaselessly with macho, paranoiac, homogenizing, and other traditional forces that continue battling over the minds and actions of women and men – forces that may indeed be far more “natural” to us human animals, who are so innately egotistical and afraid. Add to this a plague of self-righteousness, in which both individuals and political factions seem more interested in the sweet mantras of their slogans than in finding pragmatic solutions to modern problems, and you have a formula for troubled times ahead.

Inspired by these tiny sculptures, a few hyperfeminist mystics deduced a delightfully satisfying ideological fantasy — that an Earth-Mother religion preceded every other spiritual belief system, all over the planet. This ubiquitous Neolithic creed must obviously have worshipped a goddess! One whose top traits were fecundity and serene maternal kindliness. That is, till gentle Gaia was toppled by violent bands of macho Jehovah-Zeus-Shiva followers, spurred by an abrupt wave of vile new technologies — metallurgy, agriculture, and literacy — that arrived with concurrent and destabilizing suddenness, all at once shaking the tranquil old ways and toppling the pastoral mother goddess.

They saw the end coming, he thought, looking down the file of awful figures. But they were dead wrong about the reasons why. They assumed only gods had the power to wreak such havoc on their world, but people caused the devastation here.
Alex felt compassion for the ancient Pasquans—but a superior sort nevertheless. In blaming gods, they had conveniently diverted censure from the real culprit. The designer of weapons. The feller of trees. The destroyer. Man himself.

The heritage we give our children, and the myths we leave to sustain them, must work with the tug and press of life, or they will fail. Adaptability has to be enshrined alongside stability, or the ghost of Darwin will surely come back to haunt us, whispering in our ears the penalty of conceit.
We wish our descendants happiness. But over time one criterion alone will judge our efforts.
Survival.

The propensity of Earthlings to get into trouble, and to learn thereby, was the reason my owners agreed to this mad venture – although no one expected such a chain of unusual calamities as befell this ship. Your talents were underrated.

The scientists pushing Global Warming are all in it for climate study grants. Seriously, you never realized you can judo-kill that with just four words? Show… us… the… ‘grants.
