Entropy in our Everyday Lives: Active Stability

Because things naturally move to disorder over time, we can position ourselves to create stability. There are two types of stability: active and passive. Consider a ship, which, if designed well, should be able to sail through a storm without intervention. This is passive stability. A fighter jet, in contrast, requires active stability. The plane can’t fly for more than a few seconds without having to adjust its wings. This adjustment happens so fast that it’s controlled by software. There is...

 Nietzsche is the Opposite of Humanism

If one wanted to single out a thinker who represented the opposite of humanism (indeed, of pretty much every argument in this book), one couldn’t do better than the German philologist Friedrich Nietzsche (1844–1900).109 Earlier in the chapter I fretted about how humanistic morality could deal with a callous, egoistic, megalomaniacal sociopath. Nietzsche argued that it’s good to be a callous, egoistic, megalomaniacal sociopath. Not good for everyone, of course, but that doesn’t matter: the liv...

 Retelling the Allegory of the Cave

“THERE IS AN ancient legend of Old Earth that speaks of three men of Aegina, who lived in a cave deep in the mountains,” said Magnus, with the warmth of a natural storyteller. Though he had heard this story before, Ahriman found himself captivated by Magnus’ voice, the natural charisma that loaded every commanding word. “These men lived shut off from the light of the world and they would have lived in permanent darkness but for a small fire that burned in a circle of stones at the heart of t...

 Genetic Language is Abstract and Flexible

The awesome power that genetic engineering will one day place in our hands was foreshadowed recently by some experimenters at the University of Basel in Switzerland. Walter Gehring and his students were studying the effects of the eyeless gene in fruit flies. The gene is called eyeless because its absence causes flies to grow without eyes. The gene actually causes eyes to grow. Gehring and the students inserted the gene into various tissues of embryonic flies, and the embryos grew into flies ...

 Literacy Increases Compassion

The human capacity for compassion is not a reflex that is triggered automatically by the presence of another living thing. As we shall see in chapter 9, though people in all cultures can react sympathetically to kin, friends, and babies, they tend to hold back when it comes to larger circles of neighbors, strangers, foreigners, and other sentient beings. In his book The Expanding Circle, the philosopher Peter Singer has argued that over the course of history, people have enlarged the range of...

 Make It a Treat

"Make It a Treat" is similar in spirit to "everything in moderation," but still very distinct. "Moderation" suggests a regular, low-level intake of something. MIAT asks for more austerity; it encourages you to keep the special things in life special. I apply this rule in a variety of ways. For instance, I wear makeup and high heels on special occasions. But if I dressed up all the time, it would become ordinary, and I would receive fewer compliments. If makeup and heels was my everyday look, ...

 Embrace the Cosmic Perspective

At least once a week, if not once a day, we might each ponder what cosmic truths lie undiscovered before us, perhaps awaiting the arrival of a clever thinker, an ingenious experiment, or an innovative space mission to reveal them. We might further ponder how those discoveries may one day transform life on Earth. Absent such curiosity, we are no different from the provincial farmer who expresses no need to venture beyond the county line, because his forty acres meet all his needs. Yet if all ...

 Cosmists VS Terrans

I believe that the 21st century will be dominated by the question as to whether humanity should or should not build artilects, i.e. machines of godlike intelligence, trillions of trillions of times above the human level. I see humanity splitting into two major political groups, which in time will become increasingly bitterly opposed, as the artilect issue becomes more real and less science fiction like. The human group in favor of building artilects, I label the “Cosmists,” based on the word...

 The One-Electron Universe

I received a telephone call one day at the graduate college at Princeton from Professor Wheeler, in which he said, "Feynman, I know why all electrons have the same charge and the same mass" "Why?" "Because, they are all the same electron!" And, then he explained on the telephone, "suppose that the world lines which we were ordinarily considering before in time and space - instead of only going up in time were a tremendous knot, and then, when we cut through the knot, by the pl...

 The Dilemma of Human Diversity Across the Cosmos

When life spreads out and diversifies in the universe, adapting itself to a spectrum of environments far wider than any one planet can encompass, the human species will one day find itself faced with the most momentous choice that we have had to make since the days when our ancestors came down from the trees in Africa and left their cousins the chimpanzees behind. We will have to choose, either to remain one species united by a common bodily shape as well as by a common history, or to let our...
