About the Third Brain Guild
The short version
We are a community of practice for people building their second and third brains, and for everyone curious about owning the way they think, learn, and work with their tools.
A community of practice has three parts. It helps to name them, because they are the bones of this place.
- The domain is what we care about together. Ours is the Third Brain: information autonomy, data sovereignty, and owning your own mind and tools. Personal knowledge management and beyond.
- The community is the people. Ours is the Guild: peers and practitioners, masters of a craft, not students of a single guru. Everyone here is a king in their own corner.
- The practice is what we actually do. Ours is building: second brains, third brains, live systems for thinking, the methods, and the honest story of how we figured it out.
The mythic name carries the feeling. The community-of-practice frame carries the seriousness. We keep both.
The three brains
Your first brain is biological. It is brilliant and it forgets.
Your second brain is digital. It is the notes, files, links, and systems you build so you stop losing what matters. Tiago Forte gave a lot of people the language for this, and it changed how we work.
Your third brain is collective. It is what happens when a group of practitioners think together, build in the open, and pool what they learn. No single one of us holds it. It only exists in the between. That is the brain this Guild is here to grow.
What we believe
Information autonomy. You should own your information, your tools, and the way you think with them. Not rent them, not surrender them to a black box.
Many lenses, one room. There is no One True System here. Aslander, Forte, Milo, Allen, Chou, Luhmann, the 10K HP way, and whatever you brought with you, all of it lives here next to each other. You choose your teachers. We learn across the differences instead of arguing about which one wins. See 11 The Disciplines — Many Lenses, One Room.
Every language welcome. Most of the Guild runs in English, simply so we can all find each other. But you are welcome in any language. The way a concept lives differently from one tongue to the next, the local texture of it, is not noise to clean up. It is often where the real understanding hides. We treat that as a gift to the room.
Learn in public. We work on our own systems, we work together, and we share what we discover openly. The commons is readable by anyone, on purpose. This is the open, generous front of the Guild.
A connector, not a distributor. This community is held, not owned. My job, and increasingly the job of everyone who steps up, is to connect the right people for the right conversations, then get out of the way. We do not hoard knowledge. We pass it on.
Sovereign by design. A Guild about owning your tools cannot live on someone else’s silo. We are hosted in Europe, on European infrastructure, and you can verify every piece of that yourself. See 06 Sovereign by Design.
Where this came from
This did not appear from nowhere. A great deal of the thinking here grew out of the work Martijn Aslander has been doing over the last few years, through Digital Fitness and the PKM Summit, and the people, events, and ideas that gathered around all of that. Many of us first met while trying to build our own Live Lens Systems. The Guild is the coalition that formed out of it, a catalysing of people, events, and thoughts into one shared place.
That history shows. Some voices are simply more present here than others, and Martijn’s is one of them. That is lineage, not hierarchy. It is the soil this grew in, not a ranking of who is right.
And we think there is more possible than LLS alone. There are a lot of people out there who could contribute to this, and help develop it into something none of us can fully see yet. That open horizon is the invitation. We are early, and we are building it with you, not for you.
If this sounds like your kind of room, read 03 Who This Is For and Who Is Welcomed, then come say hello.
