This chapter establishes the core conceptual building blocks for the Nature-Technology spectrum by providing rigorous, reductivist definitions of nature and technology. First, nature is defined by its independence from human activity (“absence of human intervention”), which is defended as a continuum rather than a binary distinction. The chapter resolves the conceptual overlap between “naturalness"” and “wild(ness)” by advocating for their simplification into a single category. Second, technology is formally defined as a Tripartite Analysis: Intentional Functional Artifact. The chapter concludes by noting the structural analogy between this definition of technology and the classical Platonic definition of knowledge. Just like in the knowledge case, the tripartite definition of technology suffers from what we can call “techno-Gettier cases.”
