A nice metaphysical thesis 🔮 A thing that's hard to confirm or deny. Ideally, something beyond human perception while very related to existence.
Why it's important: Logical, practical, down-to-earth theses are easy to oppose during the argumentation. And they're boring because there's no drama or uncertainty.
Examples:
Abrahamic religions: There's a life after death, and you must behave to earn a good post-death existence.
Eco-activists: climate change will destroy humanity by 2050.
