““The biological imperative to live—indeed, live forever—was burned into our brains, into our emotional self-model, over the course of millennia. But our brand-new cognitive self-models tell us that all attempts to realize this imperative will ultimately be futile. Mortality, for us, is not only an objective fact but a subjective chasm, an open wound in our phenomenal self-model. We have a deep, inbuilt existential conflict, and we seem to be the first creatures on this planet to experience it consciously.””
