To think is to imagine a possibility between one possible world and another.
I used to think of thinking as something elevated. As clarity. As a movement toward truth. But more and more, it feels like the opposite. Thinking doesn't lift me out of life—it pulls me slightly away from it. This exercise has usually done extraordinary things for us. It gave us tools before we had hands steady enough to make them. It gave us language, mathematics, cities. But it also gave us the ability to suffer in advance. To feel the weight of futures that haven't arrived.
Our minds didn't evolve to see the world clearly. They evolved to predict it just well enough. Every moment is a an update to our models: past experience meeting incoming information, probabilities shifting. Early on, imagination was protection. If you could picture a lion behind the bush—even when there wasn't one—you survived longer. A false alarm was safer than a missed threat. But the same mechanism that once saved us also learned how to scare us. The mind got very good at inventing dangers, because we don't live in those worlds anymore, and can surely afford fewer predictions of danger. Our brains just like our bodies do not know what to do anymore with the version of life we live now. So we go to the gym and play games to keep our bodies and minds from decomposing. And so most of what we think is just our brains using heavy duy tools on really negligible inputs. Anxiety is now a mental illness, which would have truly been a weapon of survival in the environemnts we were built to live in.
As our simulations grew more complex, they began to detach from their source. We didn't just imagine animals—we imagined failure, exile, meaning. We built systems on top of systems: gods, nations, philosophies, spreadsheets. At some point, we started living inside the model. And as the Roman sotic philosopher, Seneca had said, "We suffer more often in imagination than in reality."
