ARS bridges
- Karl Popper’s falsifiability principle
- Ulrich Oevermann’s objective hermeneutics

This trilogy is not for everyone …
- no explosions or chase scenes
- no heroes or villains
- no confirmation of your worldview
A philosophical thought experiment disguised as a technical thriller —
about posthumanism, algorithms, and the future of democracy.
If you expect entertainment, you will be disappointed.
If you expect to think, you will be challenged.
