Invitation to dance — a conversation with Heinz von Foerster

[opening paragraph]: I met with Heinz von Foerster, Chairperson of the ASC Board of Trustees, last month at his home nestled in the Santa Cruz Mountains. Seated with the 88-year-old physicist — his frail body somehow persistent, eyes flashing with intellectual vigor — what emerged was a clear commitment to a set of guiding principles. Famed as a robust raconteur, von Foerster explicated his dedication to the path that has led him, with characteristic dignity, to these penultimate days he enjoys at Rattlesnake Hill in coastal California.
