When people say that Newton studied alchemy, what they actually mean was that he studied chemistry. He was studying what happens when you do different things to different elements. Sure he used the language of the time, but he was fundamentally doing chemistry. And the dream of the alchemists -- to turn base materials into gold -- was ultimately more or less realized when Henri Moissan created the first artificial di…

The difference between alchemy and modern chemistry is alchemy is based on a mystic, supernatural view of reality, whereas chemistry assumes reality is basically natural. That makes a huge difference, and chemistry would never have gotten very far if it had stuck with the old metaphysics.

Well it wasn't really "supernatural" at the time. It was literally a theory about the natural world. It just wasn't correct, and have since been replaced with different theories and models.

I'm just guessing here, but I suspect PG doesn't care what "most people" think about theology. He is probably writing from the perspective from an educated person who see the enormous influence of Newtonian physics, and see absolutely no benefit from his theological thinking. Seriously, who today even knows what Newtons theological theories were?

I don't think it matters what his particular theology was. What matters is that theology matters. It affects how people experience and interpret religion, which has a vast impact on the world. So the article's utter dismissal of theology as a waste of time seems misguided to me. Alchemy as well was not so ridiculous as people seem to think. Modern hatred for alchemy seems more like a way of patting ourselves on the b…

As you say dismissing alchemy is probably a bad thing too.

Alchemy was the search for the ability to transform matter (particularly Pb->Au). I rather think that nuclear fusion/fission are still consider worthy fields and that creation/discovery of an alchemist's stone - a way to convert readily between different forms of matter - would still be considered a worthy development.

I agree too with your synopsis. Physics is like the part of reality we've tamed, everything that is yet to be discovered, that's of interest to physicists, likely lies outside our laws, corollaries, and axioms as they now stand.

To me such ideas as the naive assumption that we know the limits of knowledge go hand in hand with the faith of atheism. But I digress.

I'm not sure that those lines of study were actually considered separate at the time. A century earlier than Newton's time, math and geometry were considered subfields of astronomy; and astronomy was considered the observation of the realm of the divine. Not only was there not a divide between physics and theology, people actually thought that math was a tool for studying theology (one of Copernicus' sources of incom…

It goes even deeper than that. At the time at Cambridge there was only one subject to study, called the Tripos, which included all these things. Overtime they've gradually stripped parts of the course into their own separate subjects. The only thing left is mathematics, which leads to a curious ceremony when you graduate with a maths degree which none of the other subjects have. So to Newton Theology and Maths were taught in the same major!

> Newton made three bets. One of them worked. But they were all risky. Except it was three: - Optics - Gravitation and mechanics - Mathematics There are many scientists out there who spend a lifetime on theories that turn out to be bogus, but calling it a bet is entirely missing the point.

A couple of years ago, I went to a museum exhibition of DaVinci's notebooks.

I was completely unprepared for what was my primary reaction: that DaVinci just documented every idea in his head, and that some of them just happened to pan out. But for some reason, we credit him for the small percentage of ideas that just happened to work, and ignore all the wrong ideas. To me, he didn't seem like a genius, he seemed very much like a broken clock that just happened to be right twice a day.

There's a certain survivor bias in these sorts of discussions, where we identify great contributors as taking huge risks, and so forth and so on. This is true, but we also maybe tend to give them too much credit because we ignore all their failures. We tell ourselves that's why perseverence is so important, but then turn around and make fun of people or even become angry at them for wasting our time when so many things don't turn out. The difference between perseverence and shotgun approaches to pursuing knowledge seems arbitrary to me lots of times.

If you followed every one of DaVinci's ideas, for example, you'd be screwed, because he was so wrong about so many things. Today, he'd probably be seen as a crackpot because it would be so difficult to know when his idea was right and when it was wrong. The value of his ideas lies as much in his audience, the people who realized what of his ideas was correct, as much as, if not more, than in DaVinci himself.

I guess I've grown really disillusioned with advancements in science, because so much of it involves a sort of mythmaking that seems fairy-tale to me. To me, the reality seems more distributed, involving small contributions, gradually changing over time, with a lot of randomness involved.

I don't mean to come across as saying we shouldn't encourage experimentation and tinkering, or that it shouldn't be valued. In fact, I'd argue the opposite. But at the same time something seems off about our incentive structures--the way we give credit seems off.

Think of it this way: we do science because at some level, what's correct and what's not is an empirical idea. You could have 10 very reasonable explanations and 9 of them will be wrong "just because." In many cases, being intelligent has nothing to do with why the 9 are wrong, otherwise all we'd need would be philosophy and math. So why do we pretend that the 1 person who was correct was correct because they are a genius? It seems like you can't have geniuses and a need for science at the same time.

I find this essay pretty confusing. It seems to contradict itself at some basic level. "Maybe the smartness and the craziness were not as separate as we think." This seems kind of obvious to me. Yes, creative and driven people are interested in lots of strange things. Yes, genius often means the ability to take ideas or discoveries from apparently widely different areas and tie them together to form new understanding…

I love this insight. I have often experienced in my life seeing someone come up with something really useful in the midst of spouting complete rubbish. Oddly it is about 50/50 internal and external, where half the time they stop in the middle of what they are saying and realize they have a really good idea, and half the time someone else stops them and says "hey, that could really work." or something like that. The common theme can best be described as "fearless thinking" or perhaps unconstrained thinking.

I suspect that the personality trait most closely associated with creativity like this is a lack of fear of embarrassment. When someone tells me something I have suggested is wrong I respond by asking questions to understand how they understand the topic so that I can learn from them. When you tell someone who has vested their self image in being right that they are wrong they take it personally and respond dismissively. They fight to have their point of view validated rather than understand a counter point of view. But this makes them unwilling to share partially understood topics because it could expose them to being 'wrong' in public.

Other times people self censor their own thinking. I get so frustrated when someone says "Well I thought that might be a solution to the problem but assumed it would be too expensive." That is an example of someone who had a creative idea, self censored it, and it had to come out through someone else in order to reach the collective consciousness of the group. I try really hard to have people not self censor but it is so ingrained sometimes.

And all of that then feeds back into the genius/hero narrative where the narrative of a person includes only their noteworthy accomplishments and so the perception is that people like that only do noteworthy things, and then they are impossible to live up to.

Dare to ask stupid questions, it could make you the smartest person in the room.

I got that too. The essay definitely had an anti-religious undertone to me.

You cannot study what -by definition- it's impossible to observe or measure directly or indirectly. Believing in God it's an act of faith, you cannot KNOW nothing. So yes, in modern times, theology and alchemy has the same scientific value: none

Scientific value != value. I view theology as a study of how humans characterize their relationship to that which is beyond logic: god, infinity, existence, whatever. To me, this study has individual and collective value even in modern times, despite the fact that it has no scientific value.

Yeah alchemy seem like a completely different field than astronomy today, but at the time it was considered deeply connected - the metals was corresponding to the planets and so on. Because the heavenly order was considered reflected in the earthly materials and vice versa, studying one would lead you to greater understanding of the other. For a modern viewpoint it might seem like Newton was "hedging his bets" by con…

Ptolemy is likewise revered by astronomers as one of their founding fathers but they conveniently ignore the fact that in astrological circles he occupies a similar position due to his seminal work, the Tetrabiblos. Scientists can become very selective when dealing with alternatives to their world view.

"Physics seems to us a promising thing to work on, and alchemy and theology obvious wastes of time." I'm not sure which "us" pg is referring to, but the essay gives me the impression that he meant something like "most people" (I could be reading him wrong, but that was my impression). Alchemy is obviously a waste of time -- I won't dispute that, and I suspect that "most people" would agree with that assertion. Being…

He is probably writing from the perspective from an educated person who see the enormous influence of Newtonian physics, and see absolutely no benefit from his theological thinking.

Although theological beliefs are rarely falsifiable, that doesn't mean they don't matter or render no benefit.

What is also discounted now even, when we are supposed to be smart and all learned, is that religion not only has played a fundamental role in why we, the west and roughly central-European based cultures are where they are that cannot or is foolish to discount. There is a particular reason why other non-central European cultures have brought us basically every single human achievement and every single good and positive thing around you that separates you from a brutish and savage life, which other societies simply have not been capable of developing on their own. Not recognizing that only leaves as single alternative view point that it is somehow inherent to genetics and "race" which is a far more dark perspective than acknowledging the role of society and culture and, yes, religion and the particular values it bears in the advancement of society.

When, e.g., your value system is founded on the notion that you reincarnate and have many/infinite attempts at doing good and that "good" is of a certain characteristic, then your life and choices and values and priorities are driven by that frame of mind and world view. If you are driven by the murderous and pedophilic values of islam that demands total domination through lying and killing and the murder of anyone that does not submit to islam then your values are going to form your perspective on the world that is a kind of parasitic and rapacious.

I find it rather odd that the tech industry of all sectors and disciplines would not seem to understand that the parameters and the system define and confine the behavior and outputs. You can put the most pure and perfect data into a shitty system that is broken in so many different ways and it won't output or produce anything of value or might even produce things that are dangerous.

We really are underestimating the value or not only risk and failure by dismissing it altogether and assuming and taking things for granted, but we are dismissing the humanistic and spiritualistic aspect that has played a role in human development and advancement for eons and is probably the core driver of what separated humans from animals in so many different ways.
