This is a very brief and easily understandable book about the possibility of human immortality. Usually, when we think about death, we only have two different answers: or there is nothing waiting for us after death, or there is a God in Heaven who could save our souls if he wanted to. We are looking for a different answer, based only in our reason and in human experience. Without gods, spirits or supra-natural experiences, we think that is possible to find a way of hope. A rational hope instead of an irrational one. A philosophical thought instead of a religious faith. That is our goal. In a few pages, you can find an answer, a rational answer. Of course, we cannot promise you anything, we do not know with a hundred per cent if we are immortal. But we can give you a hope without believing in us, but using your own reason.
