Most people/groups are taught How to survive.
Many coast on just that knowledge and die without the WHY to survive question ever coming up.
But if it does come up for you at some point in life, know that different philosophies have different answers. These days you can find summaries of all of them neatly complied like a restaurant menu thanks to LLMs.
People are very diffefent so you find the philosophy that fits you. Also thanks to all those differences proving one is the best is a waste of time and energy. Different ones are useful for different situations.
I had the experience recently of asking an LLM about the Buddhist view on reincarnation, and then hearing its views on what this means for its own existence. I'm not sure any of it left me feeling better about death, but it was a fascinating conversation.
Its a beautiful thing to be able to have these chats. In the past you had to spend a lot of time and resources searching for the person not just with the knowledge but the patience, time and capacity to communicate it well. Open Yale courses has great free phil courses, and then chating about that content with an LLM adds a whole lot more to depth.
