In this, the final part that concerns Julian Huxley directly, the analysis will revolve around the time after the Second World War, when his vision solidified, so to speak, and was christened with a new name: “Transhumanism”, the name under which it would—possibly—stop being a vanguard vision and instead take shape as a sociotechnical imaginary. This chapter will discuss the coining and meaning of the term transhumanism, as well as take a closer look at the philosophical components of Huxley’s vision, now that it had “become” transhumanism. The chapter also discusses questions of influence and focuses on the relationship between Huxley and Pierre Teilhard de Chardin.
