Can you step in the same river twice? Wittgenstein vs. Heraclitus
Imagine Heraclitus spending an afternoon down by the river...
These problems that he claims to see from a religious point of view tend to be technical matters of logic and language. Wittgenstein trained as an engineer before he turned to philosophy, and he draws on mundane metaphors of gears, levers and machinery. Where you find the word 'transcendent' in Wittgenstein's writings, you'll likely find 'misunderstanding' or 'nonsense' nearby.
When he does respond to philosophers who set their sights on higher mysteries, Wittgenstein can be stubbornly dismissive. Consider: 'The man who said one cannot step into the same river twice was wrong; one can step into the same river twice.' With such blunt statements, Wittgenstein seems less a religious thinker and more a stodgy literalist. But a close examination of this remark can show us not only what Wittgenstein means by a 'religious point of view' but also reveal Wittgenstein as a religious thinker of striking originality.
'The man' who made the remark about rivers is Heraclitus, a philosopher at once pre-Socratic and postmodern, misquoted on New Age websites and quoted out of context by everyone, since all we have of his corpus are isolated fragments. What is it that Heraclitus thinks we can't do? Obviously I can do a little in-and-out-and-back-in-again shuffle with my foot at a riverbank. But is it the same river from moment to moment – the water flowing over my foot spills toward the ocean while new waters join the river at its source – and am I the same person?
One reading of Heraclitus has him conveying a mystical message. We use this one word, river, to talk about something that's in constant flux, and that might dispose us to think that things are more fixed than they are – indeed, to think that there are stable things at all. Our noun-bound language can't capture the ceaseless flow of existence. Heraclitus is saying that language is an inadequate tool for the purpose of limning reality.
What Wittgenstein finds intriguing about so many of our philosophical pronouncements is that while they seem profoundly important, it's unclear what difference they make to anything. Imagine Heraclitus spending an afternoon down by the river (or the constantly changing flux of river-like moments, if you prefer) with his friend Parmenides, who says that change is impossible. They might have a heated argument about whether the so-called river is many or one, but afterwards they can both go for a swim, get a cool drink to refresh themselves, or slip into some waders for a bit of fly fishing. None of these activities is in the least bit altered by the metaphysical commitments of the disputants.
Wittgenstein thinks that we can get clearer about such disputes by likening the things that people say to moves in a game. Just as every move in a game of chess alters the state of play, so does every conversational move alter the state of play in what he calls the language-game. The point of talking, like the point of moving a chess piece, is to do something. But a move only counts as that move in that game provided a certain amount of stage-setting. To make sense of a chess game, you need to be able to distinguish knights from bishops, know how the different pieces move, and so on. Placing pieces on the board at the start of the game isn't a sequence of moves. It's something we do to make the game possible in the first place.
One way we get confused by language, Wittgenstein thinks, is that the rule-stating and place-setting activities happen in the same medium as the actual moves of the language-game – that is, in words. 'The river is overflowing its banks' and 'The word river is a noun' are both grammatically sound English sentences, but only the former is a move in a language-game. The latter states a rule for using language: it's like saying 'The bishop moves diagonally', and it's no more a move in a language-game than a demonstration of how the bishop moves is a move in chess.
What Heraclitus and Parmenides disagree about, Wittgenstein wants us to see, isn't a fact about the river but the rules for talking about the river. Heraclitus is recommending a new language-game: one in which the rule for using the word river prohibits us from saying that we stepped into the same one twice, just as the rules of our own language-game prohibit us from saying that the same moment occurred at two different times. There's nothing wrong with proposing alternative rules, provided you're clear that that's what you're doing. If you say: 'The king moves just like the queen,' you're either saying something false about our game of chess or you're proposing an alternative version of the game – which might or might not turn out to be any good. The trouble with Heraclitus is that he imagines he's talking about rivers and not rules – and, in that case, he's simply wrong. The mistake we so often make in philosophy, according to Wittgenstein, is that we think we're doing one thing when in fact we're doing another.
But if we dismiss the remark about rivers as a naive blunder, we learn nothing from it. 'In a certain sense one cannot take too much care in handling philosophical mistakes, they contain so much truth,' Wittgenstein cautions. Heraclitus and Parmenides might not do anything different as a result of their metaphysical differences, but those differences bespeak profoundly different attitudes toward everything they do. That attitude might be deep or shallow, bold or timorous, grateful or crabbed, but it isn't true or false. Similarly, the rules of a game aren't right or wrong – they're the measure by which we determine whether moves within the game are right or wrong – but which games you think are worth playing, and how you relate to the rules as you play them, says a lot about you.
What, then, inclines us – and Heraclitus – to regard this expression of an attitude as a metaphysical fact? Recall that Heraclitus wants to reform our language-games because he thinks they misrepresent the way things really are. But consider what you'd need to do in order to assess whether our language-games are more or less adequate to some ultimate reality. You'd need to compare two things: our language-game and the reality that it's meant to represent. In other words, you'd need to compare reality as we represent it to ourselves with reality free of all representation. But that makes no sense: how can you represent to yourself how things look free of all representation?
The fact that we might even be tempted to suppose we can do that bespeaks a deeply human longing to step outside our own skins. We can feel trapped by our bodily, time-bound existence. There's a kind of religious impulse that seeks liberation from these limits: it seeks to transcend our finite selves and make contact with the infinite. Wittgenstein's religious impulse pushes us in the opposite direction: he doesn't try to satisfy our aspiration for transcendence but to wean us from that aspiration altogether. The liberation he offers isn't liberation from our bounded selves but for our bounded selves.
Wittgenstein's remark about Heraclitus comes from a typescript from the early 1930s, when Wittgenstein was just beginning to work out the mature philosophy that would be published posthumously as Philosophical Investigations (1953). Part of what makes that late work special is the way in which the Wittgenstein who sees every problem from a religious point of view merges with the practical-minded engineer. Metaphysical speculations, for Wittgenstein, are like gears that have slipped free from the mechanism of language and are spinning wildly out of control. Wittgenstein the engineer wants to get the mechanism running smoothly. And this is precisely where the spiritual insight resides: our aim, properly understood, isn't transcendence but a fully invested immanence. In this respect, he offers a peculiarly technical approach to an aspiration that finds expression in mystics from Meister Eckhart to the Zen patriarchs: not to ascend to a state of perfection but to recognise that where you are, already, in this moment, is all the perfection you need.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>
The father of all giant sea bugs was recently discovered off the coast of Java.
- A new species of isopod with a resemblance to a certain Sith lord was just discovered.
- It is the first known giant isopod from the Indian Ocean.
- The finding extends the list of giant isopods even further.

A new study explains how a chaotic region just outside a black hole's event horizon might provide a virtually endless supply of energy.
- In 1969, the physicist Roger Penrose first proposed a way in which it might be possible to extract energy from a black hole.
- A new study builds upon similar ideas to describe how chaotic magnetic activity in the ergosphere of a black hole may produce vast amounts of energy, which could potentially be harvested.
- The findings suggest that, in the very distant future, it may be possible for a civilization to survive by harnessing the energy of a black hole rather than a star.
The ergosphere<p>The ergosphere is a region just outside a black hole's event horizon, the boundary of a black hole beyond which nothing, not even light, can escape. But light and matter just outside the event horizon, in the ergosphere, would also be affected by the immense gravity of the black hole. Objects in this zone would spin in the same direction as the black hole at incredibly fast speeds, similar to objects floating around the center of a whirlpool.</p><p>The Penrose process states, in simple terms, that an object could enter the ergosphere and break into two pieces. One piece would head toward the event horizon, swallowed by the black hole. But if the other piece managed to escape the ergosphere, it could emerge with more energy than it entered with.</p><p>The movie "Interstellar" provides an example of the Penrose process. Facing a fuel shortage on a deep-space mission, the crew makes a last-ditch effort to return home by entering the ergosphere of a blackhole, ditching part of their spacecraft, and "slingshotting" away from the black hole with vast amounts of energy.</p><p>In a recent study published in the American Physical Society's <a href="https://journals.aps.org/prd/abstract/10.1103/PhysRevD.103.023014" target="_blank" style="">Physical Review D</a><em>, </em>physicists Luca Comisso and Felipe A. Asenjo used similar ideas to describe another way energy could be extracted from a black hole. The idea centers on the magnetic fields of black holes.</p><p style="margin-left: 20px;">"Black holes are commonly surrounded by a hot 'soup' of plasma particles that carry a magnetic field," Comisso, a research scientist at Columbia University and lead study author, told <a href="https://news.columbia.edu/energy-particles-magnetic-fields-black-holes" target="_blank" rel="noopener noreferrer">Columbia News</a>.</p>
Event Horizon Telescope Collaboration<p>While there might not be immediate applications for the theory, it could help scientists better understand and observe black holes. On an abstract level, the findings may expand the limits of what scientists imagine is possible in deep space.</p><p style="margin-left: 20px;">"Thousands or millions of years from now, humanity might be able to survive around a black hole without harnessing energy from stars," Comisso said. "It is essentially a technological problem. If we look at the physics, there is nothing that prevents it."</p>
A popular and longstanding wave of thought in psychology and psychotherapy is that diagnosis is not relevant for practitioners in those fields.
