The branch of thought that asks what meaning, responsibility, or even identity can exist in a reality where every possibility is actualized somewhere. If every choice you could make is made by some version of you, are you responsible for any of them? If there's a branch where you're a saint and a branch where you're a sinner, which one is the "real" you? And if infinite versions of you exist across the probability dimension, is death just a local phenomenon, with other branches where you're still alive, possibly reading this definition and wondering the same thing? Spacetime-probability philosophy doesn't provide answers, but it does provide an excellent excuse for every bad decision: "Somewhere, a version of me didn't do this, so statistically, I'm only half responsible."
Spacetime-Probability Philosophy Example: "After a particularly bad breakup, he sat in deep spacetime-probability philosophy. 'Somewhere,' he thought, 'in another probability branch, we're still together, happy, maybe even watching a movie. And somewhere else, we never even met. And somewhere else, I'm the one who left first. So which version is the real me? Which version is the real her? And why does the version that's currently crying on the couch feel so much more real than all the others?' He then realized that philosophy, while profound, did not help with the crying."
