I listened to this audiobook several years ago when I was a lib; this book was written by an Israli Zionist scum. However, I was thinking about the notion of "leaving something behind" the other day

I was thinking about the notion of the meaning of life, and leaving something behind and all that jazz. I remembered this excerpt, and I was wondering if you think there is any merit on it.

People who doubt that some kind of soul or spirit really survives their death therefore strive to leave behind something a bit more tangible. That ‘something tangible’ could take one of two forms: cultural or biological. I might leave behind a poem, say, or some of my precious genes. My life has meaning because people will still read my poem a hundred years from now, or because my kids and grandchildren will still be around. And what is the meaning of their lives? Well, that’s their problem, not mine. The meaning of life is thus a bit like playing with a live hand grenade. Once you pass it on to somebody else, you are safe.

Alas, this modest hope of just ‘leaving something behind’ is rarely fulfilled. Most organisms that ever existed became extinct without leaving any genetic inheritance. Almost all the dinosaurs, for example. Or a Neanderthal family which became extinct as Sapiens took over. Or my grandmother’s Polish clan. In 1934 my grandma Fanny emigrated to Jerusalem with her parents and two sisters, but most of their relatives stayed behind in the Polish towns of Chmielnik and Częstochowa. A few years later the Nazis came along and wiped them out to the very last child.

Attempts at leaving behind some cultural legacy are seldom more successful. Nothing has remained of my grandmother’s Polish clan except a few faded faces in the family album, and at the age of ninety-six, even my grandmother cannot match names to the faces. To the best of my knowledge, they haven’t left behind any cultural creation – not a poem, nor a diary, nor even a grocery list.

If we cannot leave something tangible behind – such as a gene or a poem – perhaps it is enough if we just make the world a little better? You can help somebody, and that somebody will subsequently help somebody else, and you thereby contribute to the overall improvement of the world, and constitute a small link in the great chain of kindness. Maybe you serve as a mentor for a difficult but brilliant child, who goes on to be a doctor who saves the lives of hundreds? Maybe you help an old lady cross the street, and brighten up an hour of her life? Though it has its merits, the great chain of kindness is a bit like the great chain of turtles – it is far from clear where its meaning comes from. A wise old man was asked what he learned about the meaning of life. ‘Well,’ he answered, ‘I have learned that I am here on earth in order to help other people. What I still haven’t figured out is why the other people are here.’
