What is the absolutely smallest (nontrivial) philosophy? Perhaps something built upon **nothingness** — the mathematical empty set symbolized by *φ* or {}, from which all numbers are derived? Alternatively, a system starting with **everything**, the entire spacetime universe(s)? Or derived from a single pointlike **here-and-now**, this very instant? Could it be raw-existentialist, like theologian Paul Tillich's "Eternal Now" or John Robinson's "being-itself"?

Zen again, maybe not!
