So you can now drag-and-drop images into comments. (Thanks, LessWrong dev team!) 

Hence, this post is an excuse to build a beautiful, inspiring, powerful — and primarily visual — comment section. 

Let's celebrate all that is great about the Art of Rationality, with images. 

Rules 

  • Each answer must contain a picture. No links! 

It should be possible to just scroll through the comments and adore the artwork. There shouldn't be any need to click-through to other pages. (Think of it like a Pinterest board, if you've ever seen those.)

Adding text is fine, but consider doing it in a comment underneath your image, so it can be collapsed.  

  • Pictures should be somehow relate to the Art of Rationality, as practiced on LessWrong. 

Allowed: a breathtaking shot of a SpaceX launch; that solemn shot of Petrov deep in thought, gazing out his window; a painting of Galileo spearheading empiricism against the inquisition, ...

Not allowed: a random pretty mountain; the Mona Lisa; abstract expressionism, ...

I'll be liberal with this condition if you can give a good justification for why you chose your piece. 

  • Pictures should be beautiful art independently of their relation to rationality.

Allowed: an exquisite shot of some piece of elegantly engineered machinery; a richly colourful and swirling galaxy, ...

Not allowed: a random picture of Einstein and Gödel hanging out; a low-resolution photo of a galaxy which is cool because it represents an important advance in astronomy, but which in-and-of-itself just looks like some lame computer graphics; Petrov's own tourist photos, ...

  • Don't be a jerk, but do note if you think something is a major conflict with a virtue. 

Probably goes without saying... but don't be a pretentious art critic. The point of this thread is to pay tribute to those virtues that keep us striving to leave this world in a better place than we found it, guided by the Light of Science. Don't shout over the music. 

That being said, I do care about pictures actually representing rationality. For example, take that photo of the exhausted surgeon after a 23h heart transplant. If it turned out (hypothetical) to have been the result of really poor utilitarian calculations, and actually is in direct conflict with some of our virtues: I think it's important to note that. 

---

Note: I'm certainly not saying that the above rules are all that rationalist art is about. I'm just going for a particular vision with this comment field. Other posts can enforce other visions. :)

Self Made Man

Source by Michael Oswald

5meedstrom2y
Nice with a female version, but nicer if the artist didn't feel the need to focus on her beauty instead of strength. Makeup, really? Also, with the colored skin I have a hard time identifying her as a statue; she seems to be about to open a bleeding wound with that chisel.
2Yiar2y
Agreed!  I actually didn't reflect about her having makeup. I recall (but hopefully don't misrepresent in my paraphrasing) Julia Galef discussing that a society where people wear makeup is perhaps a more fair option since the difference between the most and least naturally beautiful people would be smaller then. I haven't thought deeply about this, but in that case, wearing makeup might be the rational thing to do. However, regarding the appraisal that the artwork represents the woman's beauty more than her strength, I can totally see how that reinforces problematic norms. Rationality is in part about taking control, and you have more control over your strength than your beauty. Still, if I could sculpt myself I would probably rather be sculpting myself pretty than musculus (well, I guess they intersect for some people). Beauty probably has more benefits than muscles these days and physical strength is much less important for rationality than mental strength. An unnecessarily muscular body might also be a sign of prioritizing the wrong things. It's hard to get the metaphors perfect and it is easy to rationalize how details make it fit or not. But it's interesting to see which metaphors resonate with the community, and would be even more interesting if more people wrote why as you did. So thanks for your perspective!
2Cedar2y
My objection to makeup is that it's sorta a zero sum game, where if everybody spends 1hr a day on makeup, the world isn't really a better place since beauty is a relative thing. I agree that, in a society where everybody is judged by their made-up looks, innate beauty would matter less, and that's good. However, people will start competing on effort spent on makeup, which to me feels like a really bad thing. Imagine everybody having to spend 2 hours on make-up every day before heading out. I think that's what some women already have to deal with in their workplaces and I'd rather not everybody's lives be like that.

Betulaster's image made me think "surely there is a version of this concept that's more polished." Turned out there were several different ones when I googled "self sculpting man". Many of them are sculptures that I suspect work best in person, but I liked this one.

An Experiment on a Bird in the Air Pump
[-]fin4y70

From Wikipedia: An Experiment on a Bird in the Air Pump is a 1768 oil-on-canvas painting by Joseph Wright of Derby, one of a number of candlelit scenes that Wright painted during the 1760s. The painting departed from convention of the time by depicting a scientific subject in the reverential manner formerly reserved for scenes of historical or religious significance. Wright was intimately involved in depicting the Industrial Revolution and the scientific advances of the Enlightenment. While his paintings were recognized as exceptional by his contemporaries... (read more)

Thanks for sharing the picture. I feel like the excerpt you posted from Wikipedia isn't the most important part. While it touches on the artistic significance of the piece, it leaves open many questions about the relevance of the piece as a symbol of rationality. I found the following excerpts from the same article to be more enlightening in this regard:

The painting depicts a natural philosopher, a forerunner of the modern scientist, recreating one of Robert Boyle's air pump experiments, in which a bird is deprived of air, before a varied group of onlookers. The group exhibits a variety of reactions, but for most of the audience scientific curiosity overcomes concern for the bird. [...] Despite the operational and maintenance obstacles, construction of the [vacuum pump] enabled Boyle to conduct a great many experiments on the properties of air [...] He listed two experiments on living creatures: "Experiment 40", which tested the ability of insects to fly under reduced air pressure, and the dramatic "Experiment 41," which demonstrated the reliance of living creatures on air for their survival. In this attempt to discover something "about the account upon which Respiration is so necessary to the Animals, that Nature hath furnish'd with Lungs", Boyle conducted numerous trials during which he placed a large variety of different creatures, including birds, mice, eels, snails and flies, in the vessel of the pump and studied their reactions as the air was removed.

I feel like photography (and in particular, photographs showing interesting physical systems) is a particularly good fit for "rationalist" artwork. For me, one of the top two or three most fundamental principles of rationality is entangling oneself with the world - living in the real world, and appreciating the real world, rather than escaping into one's own imagination. That's not to say imagination is bad, but rather that the role of imagination is to act on the real world, rather than to live on a separate plane of existence. Let the real world inform our beliefs, and use that knowledge to bring our ideas into physical reality.

Photography is a great fit for that, because it portrays physical reality. In some cases, a photograph can help us entangle our own beliefs with reality - as in scientific photographs, like an image of a cell with certain organelles stained. In other cases, a photograph can display the form of some brilliant idea made real - as in the photograph above.

Pale Blue Dot, version 2

Part of why I like this one is that I was confused by some of it, and did some research, and thus learned that the big hazy blue/white thing isn't like... a rocket's glow from near and close to the camera, but rather it is a wispy but vast object that "exists out there"!

It is the Phoebe Ring, which was predicted to exist by Steven Soter in 1974 and first observed in 2009. It is made from the ejecta dust of Phoebe which formed far from the sun, probably had water on it while it was radioactively hot, and only later was captured by Saturn in the inner system...

The true patronus was discovered (possibly rediscovered) by Harry Potter, when he finally understood that Dementors represent Death incarnate. His empathetic desire to protect all of humanity from the pain of that loss allowed him to not just drive away the fear of Death, but to conquer Death itself. This caused his Patronus to evolve into its true form; his Patronus took on the shape of an androgynous human. In this form, the Patronus gains additional abilities, including the ability to destroy Dementors and block the "unblockable" curse, Avada Kedavra.

The School of Athens

I've recently gained a better appreciation for how astonishingly good this work is at linear perspective, which had only come about in European art in the prior century. Many things about this painting are good (and some bad to my eye, like the messy color scheme) but those hexagonal details on the curved arches in perspective is 100% Raphael showing off.

An aside, but linear perspective is the most rational part of art, in the older philosophical sense of rational; it's pretty much the only major part of classical art which descends from first principles rather than having an empirical basis.

This depicts a community of scholarship.

Is the sea a metaphor for something?

2TekhneMakre2y
Hm. I didn't have anything in particular in mind, and IDK what Yerka was thinking. We could say that the sea has the quality of the Real; a vastness, that one traverses on a very narrow bridge, which seems opaque and infinitely deep--literally, un-fathom-able. Yet on closer investigation one finds, in some places, scaffolding that cleaves through the depths in thin lines, a heritage deposited by past explorers, who, having traversed inherited pathways and then struck out a bit further, turned around and set up the way for their successors--the next lantern in a line of lanterns leading down into the thoughtmines.

"Two girls sightseeing on a ringworld", by /u/Von_Grechii

I hesitated a little on whether to post this, given that it has been pointed out that the curvature of a ringworld wouldn't actually be that obvious from the inside, so it's in tension with the spirit of rationality to post a picture that depicts something physically impossible.

Still, after almost posting this, then deleting it, then feeling like I wanted to post it anyway, I decided to just do it. As I feel that it captures a combination of joy and love of life co-existing  with, and made possible by, science and rationality.

1meedstrom2y
Many ringworld depictions I've seen have primarily been "about" the ringworld, whereas this seems to successfully push the fact into the background and focus more on a "bright future"-feeling. I talk to people who are not very much scientists so this kind of painting can help show why I attach so much positive valence to science's potential, sort of.

The mysterious blue glow w/ discharges looks like Cherenkov radiation, even though I'm pretty sure it's just blue lights serving as a backdrop to some high voltage discharge.

Cherenkov radiation in a nuclear reactor at Argonne National Lab

This is basically the most sci-fi thing ever - it's like the visual director of the universe decided that high-energy radiation in water had to glow blue to show the audience that something weird was going on.

It took me a while to understand that the "blue glow" comment was directed at the electric discharges picture in the comment you replied to, and not at your own nuclear reactor picture, which is real Cherenkov radiation.

Maybe these should be moved into answers, instead of as this comment? (And as separate answers, so people can vote/discuss them separately.)

Alas, these ones don’t work for me.

  • Pictures should be somehow relate to the Art of Rationality, as practiced on LessWrong. 

Allowed: a breathtaking shot of a SpaceX launch

Not that I would have anything against nice space exploration -themed imagery, but what makes that particularly connected to the art of rationality?

(I really like this post in general though, strong-upvoted.)

Scope sensitivity and the cosmic endowment. I definitely feel like looking at the stars reminds me of how much stuff there is to optimize, which sure feels pretty related to rationality.

I'm surprised that no one has mentioned the thing that feels most rationalist-y about SpaceX, which is the exercise of agency against civilizational inadequacy. Elon Musk looked at space travel and was like, 'that seems inadequate, I bet I could do it better.' And everyone said, 'you're crazy, that's impossible.' And Elon Musk didn't listen to them and now SpaceX is a leader in space flight.

I guess the key word here might be "the Art of Rationality, as practiced on LessWrong". I do somewhat resonate with what you describe, but that feels more associated with a specific set of values that's predominant on LW due to a founder effect, rather than an integral part of rationality. So someone could still be rational in the sense that LW conceives rationality, without sharing the values implied by the concept of a cosmic endowment.

(That said, I'm cool with this thread being about that particular aesthetic, rather than rigorously just the art of rationality.)

Hmm, definitely feels core to the art of rationality to me. Like, convergent instrumental goals apply to humans as well. Understanding that just feels straightforwardly useful for the generalized art of rationality.

They certainly apply, but the formulation of the instrumental convergence thesis is very general, e.g. as stated in Bostrom's paper:

Several instrumental values can be identified which are convergent in the sense that their attainment would increase the chances of the agent’s goal being realized for a wide range of final goals and a wide range of situations, implying that these instrumental values are likely to be pursued by many intelligent agents.

That only states that those instrumental values are likely to be pursued by many agents to some extent, depending on how useful they are for fulfilling the ultimate values of the agents. But there's nothing to say that it would be particularly useful for the goals of most humans to pursue them to the point of e.g. advancing space colonization.

Scope sensitivity and the cosmic endowment.

[...] specific set of values that's predominant on LW due to a founder effect [...] this thread being about that particular aesthetic [...]

Noticing that there's lots of matter to do something with is not an aesthetic, it's awareness of a basic drive. While it's technically possible to have a preference that doesn't value things that can be made out of galaxies, it would be shocking if there is a statistically significant number of humans whose correct idealization has that property. I mean, even a paperclip maximizer is not like that.

I think it's important to avoid mixing up the question of values about what should actually happen with the world, and the question of what seems aesthetically pleasing. What habryka referenced and you seem to be responding to are (salient ideas associated with) actual values. But this post's rules state that it's something real that should have power over selection of art, not just aesthetic preference, which makes habryka's appeal to values relevant, where it would be a much weaker argument if we were only discussing aesthetic preference.

While it's technically possible to have a preference that doesn't value things that can be made out of galaxies, it would be shocking if there is a statistically significant number of humans whose correct idealization has that property.

I have pretty broad uncertainty on whether "people's correct idealization" is a useful concept in this kind of a context, and assuming that it is, what those idealizations would value - seems to me like they might incorporate a fair amount of path dependence, with different equally correct idealizations arriving at completely different ultimate outcomes.

which makes habryka's appeal to values relevant, where it would be a much weaker argument if we were only discussing aesthetic preference.

I tend to think that (like identities) aesthetics are something like cached judgements which combine values and strategies for achieving those values.

I have pretty broad uncertainty on whether "people's correct idealization" is a useful concept in this kind of a context, and assuming that it is, what those idealizations would value [...]

Understanding of a concept shouldn't directly depend on whether it's useful, so I think it's an error to entertain the assumption of usefulness. (What use were you considering? Maybe it is relevant in a way I don't see?)

Here, it doesn't matter what stuff people would value (so it isn't relevant that different people value different things or that there is a lot of uncertainty about what people value). The question is whether the total value of the-most-valuable-to-a-given-person stuff, whatever that is, made out of reachable matter is significant (compared to what can be made out of Earth). Do you mean that it's plausible that for a lot of people it isn't actually significant?

That's the question I implicitly posed in the grandparent. It's not clear from your response what you think about it. A point I would agree with is that the question is too vague to have a robust understanding of it, so heuristically it makes sense to only entertain some related considerations while holding off on articulating an answer (in the same spirit as for most stuff pundits are wont to irresponsibly opine about).

What are some beautiful, rationalist artworks? has many pieces of art that help me resonate with what rationality is about.

Look at this statue.

A rationalist must rebuild their self and their mind.
