By the time my son was four years old, he knew what growing was. He remembered being younger and he knew he would grow up to be an adult, and later grow old. He knew that 70 was old, and 100 was very old. He also knew that one does not grow indefinitely, one cannot be 1000 years old. But the concept of death was unknown to him, as is usually the case since the second half of the 20th century, as premature death is no longer a common occurrence. And I had no urge to expose him to this concept.
One day I played with him in the park, and when we were about to leave he noticed an inscribed tablet by the entrance. He asked me what it was, and I told him that the park had been dedicated to a famous poet. I told him my grandmother had known him when she was young. He asked me if we can meet him and I told him inadvertently that he was gone. His reaction clearly indicated that he had been puzzled about this subject for a long time and that my answer hit the right spot. He asked me: "so after someone becomes really old, he simply disappears?" I tried to change the subject, but his train of thought was already underway. "And after you die, are you then reborn?", he asked. Trying to keep this as open-ended as possible, especially since bringing up the subject was an accident in the first place, I told him that the Hindus believe in reincarnation. He asked me whether this belief was true, and I told him that nobody knows. I found it astonishing that he came up with this idea by himself.
Ever since that conversation, he seems to be preoccupied with death. He finds an opportunity to bring up the subject almost every day. He wants to know what may cause death. He tries to understand what death really is. The other day I showed him a book about dinosaurs, and one of the pictures in the book had a predator dinosaur by his slain prey. After we reached the end of the book, he wanted to flip back to that page: "the picture I want to see is not interesting, but I want to see it" he explained, apologetically, and gaped at the picture, trying to understand what he was seeing. This, of course, also introduced a new notion, that of killing.
Interestingly, while obviously curious about death, at the same time he seems indifferent to this possibility, he does not seem to be alarmed by it, nor does he think of it as a sad thing, more as an inevitability. While his point of view is immature and naive, one must appreciate that it is also innocent and unbiased. Is death a sad thing, apart from the loss it involves? Why does our heart miss a beat when we hear about the death of a distant relative which we haven't been in touch with for a long time? Why do we fear our own death, surely we won't feel any loss? At what stage do we adopt our understanding of death, and why?
