one philosopher has once said that to be sad about the fact of not being alive after death is as stupid as being sad about the fact of not having been alive before our birth. i don’t agree with that. we live with our past, also with the past before us. we can learn about the past and it affects our present condition. but we cannot know about the future. the sadness of possible death is from being left out, from lack of knowledge about the future, while the past of the universe is within us, inside our bodies, represented as life.
