What's the last significant new idea or philosophy you heard about and thought was really interesting?

I was astonished by the Great Green Wall Initiative in Africa. The plan is to create a continent-spanning wall of vegetation to prevent the Sahara Desert from expanding southward. It is nothing if not ambitious.

Apparently, the first phase is to create huge number of these tiny plots shaped in a special way to prevent rainwater from running off and planting drought-hardy native species in them, some of which can be harvested as a food source. Eventually, once the soil has recovered sufficiently, they can plant trees.

The initiative is high-tech in the sense of applying state-of-the-art knowledge on land management but low-tech in the sense that it will involve a whole lot of manual labour with simple implements.

But the scope of it is insane with 22 countries having signed on. It gives me hope that collective action in the face of climate change is possible anywhere in the world.

The idea that consciousness is an emergent phenomenon from less complex things working together. There’s no evidence of, for instance, a city or bee hive having “consciousness” so it’s philosophical, not scientific, but the idea appeals to me.

I think it appeals to me because it’s a bottom up approach to something we usually think of as top down. Emergence in general is very common in nature. Ants aren’t sophisticated but ant colonies can be surprisingly complex. Maybe it’s the same with our cells.

People care about thought crimes, but not thought virtues. People often judge themselves and others unnecessarily harshly for having impure thoughts, but never praise others for wanting to do good things but not doing them/not being able to. Doesn't seem very fair to me, it sucks how easy it is to latch on to bad thoughts and ideas, even when never acted upon. It's a thing I've struggled with ever since I started being more self aware of my flaws, and this thought makes it a little easier to not give so much weight to my shitty thoughts

The "Dark Forest" hypothesis of the universe. It's not at all new, but it's new to me. I find it pretty interesting. Though my personal 2-cent take on the Fermi paradox is quite different.

“If God is all-good, he can’t be all-powerful, and if he’s all-powerful, he can’t be all-good.”

I know this is just a retread of a philosophical idea that’s been around for centuries (if not millennia), but something about the way it’s phrased really grabbed my attention and made me seriously consider it.

The closest comparison I can think of is hearing a song that’s just okay, but years later hearing a cover that’s simply incredible.

You don’t have a soul, Doctor. You are a soul. You have a body, temporarily.

Reading that quote made me reflect on the distinctions between body, soul, and consciousness in a new way.

It's from the book A Canticle For Leibowitz for anyone curious.

first thing that came up for me is The Egg.

For me, it's an "anecdotal" or "more relatable" golden rule so it's nothing really new. The interesting part was how it ties cosmic beings and rebirth cycles.

Neutral Monism. Particularly applied to whether an AI that acts sufficiently human would necessarily experience consciousness.

You can add onto that Virtue Ethics, applied to the question of whether an AI which acts human but is not conscious ought to be treated as if it were conscious anyway — because to do otherwise would damage one’s moral character.

Learning about Daoism has been pretty cool though I can only really read the Dao De Jing because there are no temples near me. Buddhism is way more wind spread and easily accessible comparatively speaking. It is also how Lao Tzu and Siddhartha Gautama come to many similar conclusions about suffering and leading a good life.

Here's the bigger picture - or the self-actualization I have reached - you & I are the universe, on a journey that spans billions of years, we have come alive just for a few decades at most, in a way for the universe to experience itself, & experience we do, but we lack awareness of who we are (one / the universe), what we have (here & now), & what we truly yearn (experience the universe / connect with each other). Everything else is Leela, the most engaging movie or play you ever saw. It is so gripping, we can't look away, but it's just a show!

I was very intrigued by a follow-up to the recent numberphile video about divergent series. It was a return to the idea that the sum of the integers greater than zero can be assigned the value -1/12. There were some places this could be used, but as far as I know it was viewed as shaky math by a lot of experts.

As far as I recall the story goes something like this: now, using a new technique Terrence Tao found, a team was seemingly able to "fix" previous infinities in quantum field theory - there's a certain way to make at least some divergent series work out to being a real number, and the presenter proposed that this can be explained as the universe "protecting us" from the infinities inherent in the math.

It made me think about other places infinities show up in modern physics (namely, singularities in general relativity) and whether a technique something like this could "solve" them without a whole new framework like string theory is.

Organic compute: growing digital technology

Moore’s law and exponential technological progress viewed from the wider frame of biological evolution, and “the singularity,” are pretty compelling and likely upon first hearing them. They’re many nutters around it but Kurzweil earlier books on it are quite sound.

I was revisiting one of those old childhood truths recently about the philosophy of common sense. Someone had asked a question twice about what people gravitate to when it comes to trust, and the answers reinforced a fear I've often had. There are lessons that might make you appreciate humanity, and then there are those which make me not want to be a normal human being because of seemingly intrinsic behavioral entailments.

Dialetheism is the view that some contradictions (i.e. p and not-p) are true. The argument for this is based on the liar's paradox:

This sentence is false.

If you follow the logic through, you get the conclusion that it is both true and false. It requires some changes to Frege-Russell-style classical logic to be coherent, but it allows one to solve almost all paradoxes in one philosophical move. For example, you can have naive set comprehension principles

The ancient Hindu texts known as The Vedas possess elements common to both quantum physics and the concept of Synchronicity.
