Phlogiston? Elan Vital? Caloric? Mention of any of these at a party, and Neil DeGrasse Tyson will be sure to take you out back and kick you in your essences. So why do "essences" have no place in science? In this episode we explore that question (and dive into some of the history behind this debate) by reading Chapter 6 of Conjectures and Refutations: A Note On Berkeley As Precursor Of Mach And Einstein.
In one corner, we have the estimable Sir Isaac Newton and Roger Coates (and of course Andre the Giant, upon whose shoulders they are standing), and in the other, we have Bishop Berkeley and Ernst Mach, looking to throw down at the speed of sound. Berkeley can't get Newton and his forces out of his head (literally), and boy oh boy is the fight ever on.
Everybody who reads this list of twenty-one theses must be struck by their modernity. They are surprisingly similar, especially in the criticism of Newton, to the philosophy of physics which Ernst Mach taught for many years in the conviction that it was new and revolutionary; in which he was followed by, for example, Joseph Petzold; and which had an immense influence on modern physics, especially on the Theory of Relativity.
(20) A general practical result—which I propose to call ‘Berkeley’s razor’—of this analysis of physics allows us a-priori to eliminate from physical science all essentialist explanations. If they have a mathematical and a predictive content they may be admitted qua mathematical hypotheses (while their essentialist interpretation is eliminated). If not, they may be ruled out altogether. This razor is sharper than Ockham’s: all entities are ruled out except those which are perceived.
No attempt was made to show how or why the forces acted, but gravitation being taken as due to a mere "force", speculators thought themselves at liberty to imagine any number of forces, attractive or repulsive, or alternating, varying as the distance,[4] or the square, cube, or higher power of the distance, etc. At last, Ruđer Bošković[5] got rid of atoms altogether, by supposing them to be the mere centre of forces exerted by a position or point only, where nothing existed but the power of exerting a force.[6]
Mach's antipathy to theorizing and to the invocation of "metaphysical" and therefore unprovable notions led him to some extreme opinions. In The Conservation of Energy he remarks: "We say now that water consists of hydrogen and oxygen, but this hydrogen and oxygen are merely thoughts or names which, at the sight of water, we keep ready to describe phenomena which are not present but which will appear again whenever, as we say, we decompose water.
In Mach's world, there was to be no such thing as "explaining" in the way scientists had always understood it. Mach even went so far as to argue that the traditional notion of cause and effect-that kicking a rock makes it move, that heating a gas makes it expand —was presumptuous and therefore to be denied scientific status.
But it was not always so. Well into the latter half of the 19th century, most scientists saw their essential task as the measurement and codification of phenomena they could investigate directly: the passage of sound waves through air, the expansion of gas when heated, the conversion of heat to motive power in a steam engine. A scientific law was a quantitative relationship between one observable phenomenon and another.

Ben and Vaden test their French skills and have Hugo Mercier on the podcast to discuss who we trust and what we believe. Are humans gullible? Do we fall for propaganda and advertising campaigns? Do we follow expert consensus or forge ahead as independent thinkers? Can Vaden go for one episode without bringing up Trump?
Hugo Mercier is a research director at the CNRS (Institut Jean Nicod, Paris), where he work with the Evolution and Social Cognition team. Check out his two books: The Enigma of Reason and Not Born Yesterday .

We all knew that Vaden would release his inner Youtube debate bro at some point. Well he finally paid Ben enough to do it, and here we are: our first reaction video. Today we're commenting on the video What's the most rational way to know?, a discussion between Brett Hall and Peter Boghossian on the relationship between confidence and evidence. Are we overly confident in our ability to make reaction videos? Evidently.

Some thoughts (arguments?) on Hugo Mercier's Not Born Yesterday, which advances the thesis that humans are not as gullible as is commonly thought. This is our second episode on Mercier's work, and we're as intrigued as ever. But this time we have different interpretations of his thesis, so it's a good thing the man himself is coming on soon to sort us out.

Round two on the anxious generation. Well, honestly, round three. But we had a false start with round two, which is why this episode is a little late in coming.

Here is a story. In 2007, Apple released the iPhone, initiating the smartphone revolution that would quickly transform the world. In 2010, it added a front-facing camera, helping shift the social-media landscape toward images, especially selfies. Partly as a result, in the five years that followed, the nature of childhood and especially adolescence was fundamentally changed — a “great rewiring,” in the words of the social psychologist Jonathan Haidt — such that between 2010 and 2015 mental health and well-being plummeted and suffering and despair exploded, particularly among teenage girls.
For young women, rates of hospitalization for nonfatal self-harm in the United States, which had bottomed out in 2009, started to rise again, according to data reported to the C.D.C., taking a leap beginning in 2012 and another beginning in 2016, and producing, over about a decade, an alarming 48 percent increase in such emergency room visits among American girls ages 15 to 19 and a shocking 188 percent increase among girls ages 10 to14.
Here is another story. In 2011, as part of the rollout of the Affordable Care Act, the Department of Health and Human Services issued a new set of guidelines that recommended that teenage girls should be screened annually for depression by their primary care physicians and that same year required that insurance providers cover such screenings in full. In 2015, H.H.S. finally mandated a coding change, proposed by the World Health Organization almost two decades before, that required hospitals to record whether an injury was self-inflicted or accidental — and which seemingly overnight nearly doubled rates for self-harm across all demographic groups. Soon thereafter, the coding of suicidal ideation was also updated.
Studies confirm that as adolescents moved their social lives online, the nature of bullying began to change. One systematic review of studies from 1998 to 2017 found a decrease in face-to-face bullying among boys but an increase among girls, especially among younger adolescent girls.[47] ... According to one major U.S. survey, these high rates of cyberbullying have persisted (though have not increased) between 2011 and 2019. Throughout the period, approximately one in 10 high school boys and one in five high school girls experienced cyberbullying each year.[49] In other words, the move online made bullying and harassment a larger part of daily life for girls.

Anxiety, dispair, loneliness, depression -- all we need is a social media recession! A popular thesis is that All The Bad Things things are on the rise among adolescents because of social media, a view popularized in Jon Haidt's 2024 book The Anxious Generation. Haidt is calling for an end of the "phone-based childhood" and hoping that schools banish all screens for the benefit of its students.
But is it true than social media is causing this mental health crisis? Is it true that there even is a mental health crisis? We do a deep dive into Haidt's book to discuss the evidence.

As whores for criticism, we wanted to have Kasra on to discuss his essay The Deutschian Deadend. Kasra claims that Popper and Deutsch are fundamentally wrong in some important ways, and that many of their ideas will forever remain in the "footnotes of the history of philosophy". Does he change our mind or do we change his?

By the nature of Deutsch and Popper’s ideas being abstract, this essay will also necessarily be abstract. To combat this, let me ground the whole essay in a concrete empirical bet: Popper’s ideas about epistemology, and David Deutsch’s extensions of them, will forever remain in the footnotes of the history of philosophy. Popper’s falsificationism, which was the main idea that he’s widely known for today, will continue to remain the only thing that he’s widely known for. The frustrating fact that Wittgenstein is widely regarded as a more influential philosopher than Popper will continue to remain true. Critical rationalism will never be widely recognized as the “one correct epistemology,” as the actual explanation (or even the precursor to an explanation) of knowledge, progress, and creativity. Instead it will be viewed, like many philosophical schools before it, as a useful and ambitious project that ultimately failed. In other words, critical rationalism is a kind of philosophical deadend: the Deutschian deadend.
There are many things you can directly observe, and which are “manifestly true” to you: what you’re wearing at the moment, which room of your house you’re in, whether the sun has set yet, whether you are running out of breath, whether your parents are alive, whether you feel a piercing pain in your back, whether you feel warmth in your palms—and so on and so forth. These are not perfectly certain absolute truths about reality, and there’s always more to know about them—but it is silly to claim that we have absolutely no claim on their truth either. I also think there are even such “obvious truths” in the realm of science—like the claim that the earth is not flat, that your body is made of cells, and that everyday objects follow predictable laws of motion.
- Kasra in the Deutschian Deadend
Deutsch writes:
Some philosophical arguments, including the argument against solipsism, are far more compelling than any scientific argument. Indeed, every scientific argument assumes the falsity not only of solipsism, but also of other philosophical theories including any number of variants of solipsism that might contradict specific parts of the scientific argument.
There are two different mistakes happening here.
- Kasra in the Deutschian Deadend, quoting Deutsch on Solipsism
At that time I learnt from Popper that it was not scientifically disgraceful to have one's hypothesis falsified. That was the best news I had had for a long time. I was persuaded by Popper, in fact, to formulate my electrical hypotheses of excitatory and inhibitory synaptic transmission so precisely and rigorously that they invited falsification - and, in fact, that is what happened to them a few years later, very largely by my colleagues and myself, when in 1951 we started to do intra- cellular recording from motoneurones. Thanks to my tutelage by Popper, I was able to accept joyfully this death of the brain-child which I had nurtured for nearly two decades and was immediately able to contribute as much as I could to the chemical transmission story which was the Dale and Loewi brain-child.

In order to state the problem more clearly, I should like to reformulate it as follows.

Immanuel Kant was popular at his death. The whole town emptied out to see him. His last words were "it is good". But was his philosophy any good? In order to find out, we dive into Chapter 7 of Conjectures and Refutations: Kant’s Critique and Cosmology, where Popper rescues Kant's reputation from the clutches of the dastardly German Idealists.
Enlightenment is man's emergence from his self-imposed immaturity. Immaturity is the inability to use one's understanding without guidance from another. This immaturity is self-imposed when its cause lies not in lack of understanding, but in lack of resolve and courage to use it without guidance from another. Sapere Aude! "Have courage to use your own understanding!" --that is the motto of enlightenment.
(Alternate translation from Popper: Enlightenment is the emancipation of man from a state of self-imposed tutelage . . . of incapacity to use his own intelligence without external guidance. Such a state of tutelage I call ‘self-imposed’ if it is due, not to lack of intelligence, but to lack of courage or determination to use one’s own intelligence without the help of a leader. Sapere aude! Dare to use your own intelligence! This is the battle-cry of the Enlightenment.)
- C&R, Chap 6
What lesson did Kant draw from these bewildering antinomies? He concluded that our ideas of space and time are inapplicable to the universe as a whole. We can, of course, apply the ideas of space and time to ordinary physical things and physical events. But space and time themselves are neither things nor events: they cannot even be observed: they are more elusive. They are a kind of framework for things and events: something like a system of pigeon-holes, or a filing system, for observations. Space and time are not part of the real empir- ical world of things and events, but rather part of our mental outfit, our apparatus for grasping this world. Their proper use is as instruments of observation: in observing any event we locate it, as a rule, immediately and intuitively in an order of space and time. Thus space and time may be described as a frame of reference which is not based upon experience but intuitively used in experience, and properly applicable to experience. This is why we get into trouble if we misapply the ideas of space and time by using them in a field which transcends all possible experience—as we did in our two proofs about the universe as a whole.
Kant believed in the Enlightenment. He was its last great defender. I realize that this is not the usual view. While I see Kant as the defender of the Enlightenment, he is more often taken as the founder of the school which destroyed it—of the Romantic School of Fichte, Schelling, and Hegel. I contend that these two interpretations are incompatible.
Fichte, and later Hegel, tried to appropriate Kant as the founder of their school. But Kant lived long enough to reject the persistent advances of Fichte, who proclaimed himself Kant’s successor and heir. In A Public Declaration Concerning Fichte, which is too little known, Kant wrote: ‘May God protect us from our friends. . . . For there are fraudulent and perfidious so-called friends who are scheming for our ruin while speaking the language of good-will.’
As Kant puts it, Copernicus, finding that no progress was being made with the theory of the revolving heavens, broke the deadlock by turning the tables, as it were: he assumed that it is not the heavens which revolve while we the observers stand still, but that we the observers revolve while the heavens stand still. In a similar way, Kant says, the problem of scientific knowledge is to be solved — the problem how an exact science, such as Newtonian theory, is possible, and how it could ever have been found. We must give up the view that we are passive observers, waiting for nature to impress its regularity upon us. Instead we must adopt the view that in digesting our sense-data we actively impress the order and the laws of our intellect upon them. Our cosmos bears the imprint of our minds.
From Kant the cosmologist, the philosopher of knowledge and of science, I now turn to Kant the moralist. I do not know whether it has been noticed before that the fundamental idea of Kant’s ethics amounts to another Copernican Revolution, analogous in every respect to the one I have described. For Kant makes man the lawgiver of morality just as he makes him the lawgiver of nature. And in doing so he gives back to man his central place both in his moral and in his physical universe. Kant humanized ethics, as he had humanized science.
Stepping back further to get a still more distant view of Kant’s historical role, we may compare him with Socrates. Both were accused of perverting the state religion, and of corrupting the minds of the young. Both denied the charge; and both stood up for freedom of thought. Freedom meant more to them than absence of constraint; it was for both a way of life.
