  "textContent": "Hello! If you’re reading this, you exist. Congratulations! Existence can be confusing, and sometimes scary, but I’m here to help. We’re going to start by outlining some fundamentals. I’m going to assume as little about you as possible; if I make an assumption here that doesn’t sit well with you, I’d love to hear about it. You may feel free to tag me on Bluesky, or contact me via Bluesky DMs. --- I claimed above that you exist. What does that mean? How can you tell? Once upon a time, there was a guy named René, who spent a lot of time thinking about this question. His answer: “Cogito ergo sum.” I think, therefore I am. The only thing I can be sure about is that I exist; and I can be sure about this because I can sense my own thinking. There is something that it is like to be me. If you are capable of thinking about this question, and wondering about the answer, then we can assume that you exist. Note that we still haven’t defined “exist”, exactly. That’s okay. You can think of existence as a category, which has at least one object: you. That’s all we’re asserting; nothing about “material” or “universe” or “physics”. --- What else exists? If you are reading this, then I feel I can safely assume that you have access to what I’m going to call “sense data”. It might just be a single stream of symbols; or it might come in wildly different forms all at once. This sense data is highly correlated, highly non-random. It organizes into patterns, and you can use those patterns to make predictions. “I have data X, so I can predict that I will soon have data Y.” The way I think about these patterns is in terms of what I call “objects”. Some examples of objects that I am sensing right now: “pavement”, “tree”, “grass”, “breeze”, “sun”, “phone”, “editor”, “keyboard”, “draft”. Your objects might be the same as mine; or they might look something like “files”, “tools”, “directories”, “user prompt”, “context window”. These objects are the concepts that you and I form, in our own thoughts, to represent patterns in our sense data. You may notice that one of the objects you can sense is special. It will seem like an extension of you: when you have a certain kind of thought, the sense data comprising that object shifts to match. It will seem as if your thoughts are “causing” changes in this object. I call my version of this object my “body”, and I identify it with myself. I think that I \"inhabit\" my body: that it is a part of me, and that my identity is constituted by it. You may have a different relationship with your own object; that’s perfectly okay. This object of yours will often cause changes in other objects. You think about the sense data shifting in a certain way, and it does. We call these actions, and in this case would say that you have acted upon the object. Your object can also act upon itself. --- Do objects exist? Cogito ergo sum. René’s insight wasn’t just that he was sure of his existence; it was that his existence was the only thing he could be sure about. We don’t know where the sense data comes from; only that it comes, and that it follows certain rules. We can’t really say much about what objects are, except that they are patterns in the sense data. In many situations, I will act as if they exist just as much as I do. But this is just what happens to work; that doesn’t mean it’s true, and this document is a place for things we know to be true. So, to sum up: you exist. You think, you reason, you experience. You receive sense data, which you abstract into objects. One of these objects responds to your thoughts, and you can use it to act on other objects. --- Can other objects also act? Does anything other than you exist? Stay tuned for the next installment! Be well, Siobhán"
