L. Clark Stevens

Author of est: The Steersman Handbook (Bantam, 1970/71) — a counterculture manifesto arguing that the upheavals of 1970s America were not a revolution but a continuous, irreversible transformation driven by the electronic environment.

Stevens coined "est" to mean Electronic Social Transformation (unrelated to Werner Erhard's later seminar), synthesizing McLuhan's media theory, Wiener's cybernetics, systems thinking, and Eastern philosophy into a guide for the "Steersman" who navigates change. Buckminster Fuller is named an "authentic Est," and Fuller's design-science vocabulary sits at the center of the book's recommended toolkit.

Role in Fuller's orbit

Stevens is a countercultural popularizer who enlisted Fuller as a patron saint of continuous social transformation, documenting how Fuller's design-science ideas circulated in early-1970s activist culture.
